Factors Affecting Exploitation of Mineral Resources around

Generally the higher grade ores are more economic to work, not only because they yield large amount of metal but also because their higher metal content makes them easier and cheaper to smelt. Minerals of high value such as gold, diamonds, copper, uranium, can often be mined at very high cost, because they are in great demand and fetch high prices.

Ore Dilution Recovery in Mining

5/4/2017· The stoping method may affect the percentage of ore minerals recovered in the ore dressing plant, especially where certain sulfide ores are concentrated by flotation. Thus, a stoping method that permits immediate removal of the ore after it is broken so as to preclude its partial oxidation before it goes to the mill may be desirable or necessary.
