Metallurgist Roles in Mining Companies

Mining of metals and minerals is a growth industry, especially in Africa, providing job opportunities for metallurgists to work in various roles. Positions are well paid as metallurgists are required to have at least one degree from an accredited university or college. The preferred qualifications are a Bachelors Degree in Extractive Metallurgy or Metallurgical Engineering or BSc. in Chemical Engineering with a major in Mineral Processing. This is not a profession where candidates can learn the required skills on the job although experience can be gained throughout their career by expanding their exposure to different types of work on mines.

The type of work they do

The most common metallurgist roles include project management, consulting, technical or site management and research. For example, on a mine he/she would be expected to:

•    Design work programs and manage all metallurgical testing both in-house and with external service providers and laboratories

•    Work with the senior team to review and evaluate technical solutions

•    Liaise with geologists and other technical personnel to ensure the most suitable metallurgical solution is understood and employed

•    Constantly re-evaluate the metallurgical performance

At middle management level, as a project manager they would coordinate day-to-day mining activities, manage quality assurance and generally ensure a smooth operation. Mining companies look for a minimum of 5 years experience before they post these types of managers to remotely located mines. At the most senior level metallurgists can become mine managers which includes coordinating all operations, staffing, running the site itself, selecting the extraction process, and resolving operational and business issues.

Furthering a career

Metallurgists with further education and extensive experience in many technical processes become professional consultants or researchers either working directly for a large mining company or for a consulting firm contracted to it. Their role may be to advise clients on process engineering, to perform cost analyses or do budgeting. They may get involved in environmental impact assessments, HSEQ and social responsibility as well. The mining industry is constantly updating its methods of extraction and waste management in order to stay profitable and needs researchers to continue to explore new methods and processes. Pay levels vary depending on work experience, area of expertise and the location where they are posted.

Some of the personal attributes required to be successful in this field are to be an effective team player, have a high level of inter-personal communication skills and be able to express yourself in writing. A good knowledge of French is often asked for when an African posting is offered. Because of inhospitable locations and remoteness of mines, most of the postings attract single people or more mature staff who do not have school-going children.

Ancient Basic Tools to Green Light Laser: The Evolution of Mining

Mining is the process of extracting minerals and geological materials from the earth. Miners help recover many elements. These materials are rare as they are not grown, agriculturally processed or artificially created. Precious metals, coal, diamonds, and gold are just some of these materials. Mining also helps man to unearth non-renewable energy source like natural gas, petroleum, and even water. The job of miners can be difficult and risky. Thanks to efficient mining equipment, the task is a lot easier now.

People of the ancient time made use of the earth for many purposes. One way to make a living at the time is by mining. Equipment were not fully developed but people managed to unearth many precious stones and different kinds of metals. They use these minerals and elements in making basic tools for hunting and warfare. High quality flints found in masses of sedimentary rocks were in-demand in many parts of Europe. People used these flints as weapons during the Stone Age.

Ancient Egyptians were among the first to successfully get minerals from earth. Their advanced level of civilization made it possible for them to produce quality mining tools. They mined malachite and gold. Malachites are green stones used for pottery and as ornaments. The Egyptians started to quarry for other minerals not found in their soils. They head to Nubia, a part of Africa. There they used iron tools as mining equipment. That was the time when fire-setting was used to extract gold from ores. This method involves setting the rock containing the mineral against another rock, heat it and douse it with water. This was the most effective mining method that time.

The Romans also played an important part in the history of mining. They were the first to use large scale quarrying methods. An example of this is the application of volumes of water to operate simple machinery and remove debris. This is the birth of hydraulic mining.

The demand for metal increased dramatically in the 1300s. This was the time when swords, armors, and other weapons were in-demand. For this reason, miners looked for more sources of iron and silver. There was also an increase in the demand for coins that caused shortage of silver. Iron, on the other hand, was utilized in building constructions. With the high value of these materials, machineries and other mining equipment became in demand in the market.

These machines and equipment were the mothers of the present mining tools that we have today. Miners today use bulldozers, explosives and trucks. More advanced form of mining tools includes the use of green light laser serving as saw guides and machine alignment. With all these modern equipment, miners now have a safer and faster process to break down rocks and even carve out mountains. All these materials are produced and applied with the principles of engineering.

As of today, there are five major mining categories. They are coal, metal ore, non-metallic mineral mining, oil and gas extraction. Oil and gas extraction is among the biggest industries in the world today.

The Equipment Used in Mining

Bureau of Labor statistics reported that there are five major segments in the mining industry. They are gas and oil extracting, coal mining, non-metal mineral mining, metal ore mining and the supporting activities. In this matter, each segment might need different equipment. But, there are some types of mining equipment that are used by all segments of the mining industry.

Excavators

Excavators are types of equipment that are used by the miners to break and remove soil today. Traditionally, they used steam shovels and shovels to do the jobs. An excavator is a vehicle that moves with standard wheels or moves on tracks. There is a rotating platform and a bucket to its end for digging the soil.

Draglines

Draglines are very big earth moving machines that are used in mining industry. These machines are used to expose the underlying mineral deposits. These are also used to drag away the dirt. The Kentucky Coal Education said that draglines are one of the largest machine in the world. These can remove several hundred tons of the material in one pass.

Drills

Drills are very important for miners that extract natural gas and oil. Miners use these machines to reach underground deposits before they pipe the resources to the surface. Instead of being used in gas and oil mining, these machines are also used to mine coal and mineral.

Roof bolters

These machines are used to prevent underground collapses when the mining process is in progress. These are also used to support the tunnel roofs in mining location.

Continuous miners and longwall miners

These machines are usually used by subterranean coal miners. These machines are used to scrape coal from the coal beds. Meanwhile, the longwall miners are machines that are used to remove large, rectangular sections of coal instead of scraping coal from a bed.

Rock duster

These are pressurized pieces of equipment that are used in coal mining to spray inert mineral dust over the highly flammable coal dust. This inert dust will help prevent accidental explosions and fires.

Coal Seam Gas - Extraction and Processing

With rapidly depleting natural resources, people around the globe are looking for new sources of energy. Lots of people don't think much of it, but doing this is an excellent ecological move forward and may even be a lucrative endeavour. Australia has one the most significant deposits of a recently discovered gas known as coal seam gas. The deposit present in areas such as New South Wales is far more significant than the others since it contains little methane and much more carbon dioxide.

What is coal seam gas?

Coal bed methane is the more general term for this substance. It is a form of natural gas taken from substantial coal beds. The existence of this material usually spelled hazard for many sites. This stopped in recent decades, when specialists discovered its potential as an energy source. It's now among the most important sources of energy in a number of countries, particularly in North America. Extraction within australia is actually rapidly developing because of rich deposits in various parts of the country.

Extraction

The extraction procedure is reasonably challenging. It calls for heavy drilling, water pumping, and tubing. Though there are a variety of different processes, pipeline construction(an initial step) is perhaps one of the most important. The foundation of the course of action can spell a real difference between the failure or success of your undertaking.

Working with a Contractor

Pipeline construction and design is serious business. Seasoned contractors may be hard to get considering the fact that Australia's coal seam gas industry is still fairly young. You'll find only a limited number of completed and working projects across the country. There are several things to consider when getting a contractor for the project.

Find one with substantial experience within the industry sector. Some service providers have operations outside the country, especially in Canada And America. This is something you should look out for, as advancement of the gas originated there. Providers with completed projects in the said area can have the solutions required for any project to take off.

The construction process involves several basic steps. It is important the service provider you work with addresses all of your needs. Below are a few of the important supplementary services to look for.

- Pipeline design, production, and installation

- Custom ploughing (to achieve specialized trenching requirements)

- Protection and repair of pipelines with the use of various liners

- Pressure assessment and commissioning

These are only the fundamentals of pipeline construction. Sourcing coal seam gas involves many others. Do thorough research to ensure the service provider you employ is capable of completing all the necessary tasks. Other elements of the undertaking include engineering plus site preparation and rehabilitation. This industrial sector may be profitable if one makes all of the proper moves.

Avoid making uninformed decisions by doing as much research as you possibly can. Use the web to your advantage to look into a company's profile. Look for a portfolio of the projects they have completed in the past. You can gauge their trustworthiness based on their volume of clients. Check out the scope of their operations and the projects they finished.

You should also think about company policies concerning the quality of their work, safety and health, along with their policies concerning communities and the environment. These are seemingly minute but important details when searching for a contractor for pipeline construction projects.

Why common measures taken to prevent scraping aren't effective

Bots became more powerful in 2014. As the war continues, let’s take a closer look at why common strategies to prevent scraping didn’t pay off.

With the market for online businesses expanding rapidly, the development teams behind these online portals are under great amounts of pressure to keep up in the race. Scalability, availability and responsiveness are some of the commonly faced problems for a growing online business portal. As the value of content is increasing, content theft has become an increasing problem in the form of web scraping.

Competitors have learned to stay ahead of the race by using bots to scrape. While how these bots could be harmful is something worth talking about, it is not the main scope of this article. This article discusses some of the commonly used weapons to fight bots and brings to light their effectiveness in reality.

We come across many developers who claim to have taken measures to prevent their sites from being scraped. A common belief is that these below listed techniques reduce scraping activities significantly on a website. While some of these methods could actually work in concept, we were interested to explore how effective they were in practice.

Most Commonly used techniques to Prevent Scraping:

•    Setting up robots.txt – Surprisingly, this technique is used against malicious bots! Why this wouldn’t work is pretty straight forward – robots.txt is an agreement between websites and search engine bots to prevent search engine bots from accessing sensitive information. No malicious bot (or the scraper behind it) in it’s right mind would obey robots.txt. This is the most ineffective method to prevent scraping.

•    Filtering requests by User agent – The user agent string of a client is set by the client itself. One method is to obtain this from the HTTP header of a request. This way, a request can be filtered even before the content is served to the request. We observed that very few bots (approximately less than 10%), used the default user agent string which belonged to a scraping tool or was an empty string. Once their requests to the website were filtered based on the user agent, it didn’t take too long for scrapers to realize this and change their user agent to that of any well known browser. This method merely stops new bots written by inexperienced scrapers for a few hours.

•    Blacklisting the IP address – Seeking out to an IP blacklisting service is much easier than having to perform the hectic process of capturing more metrics from page requests and analyzing server logs. There are plenty of third party services which maintain a database of blacklisted IPs. In our hunt for a suitable blacklisting service, we found that using a third party DNSBL/RBL service was not effective as these services blacklisted only email spambot servers and were not effective in preventing scraping bots. Less than 2% of scraping bots were detected for one of our customer’s when we did a trial run.

•    Throwing CAPTCHA – A very well know practice to stop bots is to throw CAPTCHA on pages with sensitive content. Although effective against bots, CAPTCHA is thrown to all clients requesting the web page irrespective of whether it is a human or a bot. This method often antagonizes users and hence reduces traffic to the website. Some more insights to the new NO CAPTCHA Re-CAPTCHA by Google can be found in our previous blog post.

•    Honey pot or Honey trap – Honey pots are a brilliant trap mechanism to capture new bots (scrapers who are not well versed with structure of every page) on the website. But, this approach poses a lesser known threat of reducing the page rank on search engines. Here’s why – Search engine bots visit these links and might get trapped accidentally. Even if exceptions to the page were made by disallowing a set of known user agents, the links to the traps might be indexed by a search engine bot. These links are interpreted as dead, irrelevant or fake links by search engines. With more such traps, the ranking of the website decreases considerably. Furthermore, filtering requests based on user agent can exploited as discussed above. In short, honey pots are risky business which must be handled very carefully.

To summarize, these prevention strategies listed are either weak or require constant monitoring and regular maintenance to keep them effective. In practice bots are far more challenging than they actually seem to be.

What to expect in 2015?

With increasing need for scraping, the number of scraping tools and expert scrapers are also increasing which simply means bots are going to be an increasing problem. In fact, the usage of headless browsers i.e, browser like bots which are used to scrape are increasing and scrapers are no longer relying on wget, curl and html parsers. Preventing malicious bots from stealing content without actually disturbing the genuine traffic from humans and search engine bots is just going get harder. By the end of the year, we could infer from our database that almost half of an average website’s traffic is caused by bots. And a whopping 30-40% is caused by malicious bots. We believe this is only going to increase if we do not step up to take action!

p.s. If you think you are facing similar problems, why not request for more information? Also, if you do not have the time or bandwidth for taking such actions, scraping prevention and stopping malicious bots is something we provide as a service. How about a free trial?
