Sulfide ores undergo a five-step process: 1) the ore is crushed into a fine sand to loosen the copper minerals; 2) it is froth floated, where the sand is mixed with water and chemicals to make the copper particles water repellent; 3) air is passed through the mixture, allowing the copper minerals to attach to bubbles and float to the surface; 4 ...

The mined copper ore is initially crushed by the jaw crusher, and after being crushed to a reasonable fineness, it is uniformly fed into the wet ball mill by the elevator and the miner, and the ore is crushed and ground by the wet ball mill. The fine copper ore ground by the ball mill enters the next process: classification.

The smelting and converting of copper sulfide concentrates result in a "blister" copper that contains 97 to 99 percent of the silver present in the original concentrate. Upon electrolytic refining of the copper, insoluble impurities, called slimes, gradually accumulate at the bottom of the refining tank. These contain the silver originally ...

The social impacts of lithium mining depend on how mining companies behave and how governments regulate them. Ideally, communities that host lithium mining would share in the economic benefits, and not be left on their own to deal with cleanup and the loss of local resources—though this is far from always the case.

Cobalt is mined across the world and the vast majority is produced as a by-product from large scale copper and nickel mines. The process of cobalt mining involves many steps, including locating suitable deposits and extracting the ore before refining it into a usable form. Cobalt is only extracted alone in Morocco and some Canadian arsenide ores.

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.

The molten matte is then taken through a converter furnace where it is heated further and air is blown through the molten material to oxidize the remaining sulfur and iron. This process results in blister copper which is about 98-99% pure. Pyro-refining entails further heating to eliminate other impurities to get metallic copper with higher purity.
