COPPER Copper production

Copper production About 80 % of primary copper production comes from low-grade or poor sulfide or After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods Generally, copper extraction follows the sequence (see Figure below): 1 Beneficiation by froth flotation of ore to give copper concentrate...

Uranium processing

Uranium milling After mining, uranium ore is transported to a nearby mill for processing The first step is to crush the ore and mix it with water so that it can move through a series of mill circuits After crushing, the ore is treated with acid in large tanks, to separate the uranium from other minerals in the rock The uranium is now part of a liquid solution, which is then separated from ....
