Mineral Processing Introduction MetSolve Labs

Generally, mineral processing begins when an ore is delivered from a mine, to a processing facility. At this point, the ore is called run of mine material because there has been no treatment performed on it. There are three primary types of run of mine materials Run of mine consisting of useful materials.

Digging deeper Mining methods explained Anglo American

Large scale mechanised mining methods we use include long wall mining, where a long wall of coal is mined in a single slice, usually by a large machine. sub level caving, where levels of the ore are blasted by explosives; and ; block caving, where large areas of the ore body are blasted and then extracted with the assistance of gravity.
