Coal Mining and Processing
Surface mining. Surface mining is used to produce most of the coal in the U.S. because it is less expensive than underground mining. Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, giant machines remove the top-soil and layers of rock to expose large beds of coal.
Physical Processing: Innovations in Mineral Processing
It is estimated that there are about 2500 metal producing mines, 2500 industrial minerals operations, and almost 100,000 quarries producing aggregates for construction purposes that are of "industrial scale" (not small scale or artisanal mining) operations (Ericsson 2012).Open-pit mining accounts for about 83 % of the total industrial metal mining …

Essential Guide to Mineral Processing & Equipment
Mineral processing is a form of extractive metallurgy that separates valuable minerals from the ore into a concentrated, marketable product. Mineral processing is also known as mineral dressing. Mineral processing is conducted at the site of the mine and is a highly mechanical process, with oversight from a central control room.
