Optimizing throughput for a SAG mill is a complex process that is limited by multiple, traditionally hard to measure, variables. Historically, critical process variables relating to liner wear and ore variation have not been well accounted for using traditional instrumentation, and optimization systems were

Surface mining technology success

Feb 23, 2021At our mine, we sometimes cut up to 1,800 tons of coal per hour with one surface miner." In addition, eliminating the need for drilling and blasting and instead using surface mining technology results in a number of other benefits. First of all, it increases the safety of open-cast mining by eliminating the need to store and handle explosives.

Study of geological materials with Raman Spectroscopy

Natural rocks composing the Earth are complex. They consist of an aggregate of one or more minerals. Each mineral can be defined by its chemical composition and its crystalline structure and sometimes can also contain fluid inclusions. Geologists need a powerful characterization technique to get detailed information on the rock formation history. Raman spectroscopy is extremely information

42% of global coal power plants run at a loss, finds world

Nov 30, 2021New wind and solar will be cheaper than 96% of existing coal power by 2021. LONDON, November 30 – Two-fifths of the world's coal power stations are already running at a loss, finds Carbon Tracker in a unique study released today which challenges the need for new coal generation and shows that it makes economic sense to close plants in line with the Paris Climate Agreement.

Apr 02, 2021The transition may also have gender-differentiated impacts: men represent the largest share of the workforce of most negatively affected industries (e.g. coal-mining) while the growth of the renewable power generation sector, which exhibits a relatively more gender-balanced workforce, suggests that employment may increase in the

Study Engineering

Aug 04, 2021Mining refers to the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, vein or coal seam. Students who specialise in this area will develop a sound understanding of civil and mining engineering concepts and design, construct and manage mining projects for large multinational mining companies.

Video: Coal waste as a remedy for coal mine and water

Jul 22, 2021When extracted during coal mining and crushed into a powder, organic nano humus can be used to remove heavy metals from wastewater and as a soil amendment for land reclamation purposes. Tests with high concentrations of the waste material demonstrated 90% removal of cadmium after 15 minutes and 93% removal after 24 hours. The nano humus could also replace straw and

Poland Grapples With Coal Transition as It Holds on to

Sep 03, 2021While coal currently makes up nearly 80 percent of Poland's source of energy, the industry employs around 80,000, down from the nearly 400,000 in the early 1990s. Still, there is reluctance to publicly denounce coal to avoid angering the country's politically aligned coal mining

Particle Analysis in Mining and Minerals

Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.
