The Mining Process Newmont Corporation About Us

There are two types of mine designs for mineral mining: surface (open pit) and underground. Surface. Surface mines are generally preferred if the ore body is relatively shallow and uniform, and are made by digging into the Earth’s surface one layer at a time.

Basics of an open pit mine

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.

Mineral Processing Part 1 Geology for Investors

Nov 13, 2020· Introduction. The area has been explored, the deposit has been modeled, and the ore has been extracted: now what?It’s time for mineral processing. Mineral processing is the first thing that happens to ore and mineral-bearing rock after they leave the mine or quarry.. There are four steps in mineral processing: sampling/analysis, comminution, separation/concentration, and dewatering.
