Ore Sorting Pre-Concentration - 911 Metallurgist

2016-7-12  Ore Sorting helps the economics of mining when ore becomes diluted by country rock because of narrow slopes or because of weak wall rock, or when it naturally contains barren material which is distinguishable from the ore, sorting and rejecting the worthless rock may be economical. This is done in a casual manner at some small mines and on a large scale at others, as was the case at

Integrated mining, pre-concentration and waste

The integration of automated ore pre-concentration and waste disposal functions into the hard rock metal mining system, prior to treatment by conventional grinding and flotation, is proposed as a novel interpretation of Mine-Mill Integration for improving the economics and environmental impact of exploiting deep, low-grade or otherwise marginal mineral deposits. The proposed approach seeks to ...

Reading: Mining and Mineral Use Geology

Underground mining is used to recover ores that are deeper into Earth’s surface. Miners blast and tunnel into rock to gain access to the ores. How underground mining is approached – from above, below, or sideways – depends on the placement of the ore body, its depth, concentration of ore, and the strength of the surrounding rock.
