Copper Malachite

Copper mining usually adopts two methods: open-pit mining and underground mining. Open pit mining is carried out by stripping surface rocks and uncovering copper deposits; Underground mining refers to the mining method of excavating or excavating underground to obtain valuable minerals.

As early as 3000 BC, the ancient Egyptians began using copper. They melted the copper ore into copper ingots, which were used to make weapons and decorations. Subsequently, the mining of copper mines rapidly developed in Israel, Egypt, Rome, Greece, and ancient India, and it was also used to make copper utensils, pots and pans, and other items.

The first stage of any process within a metallurgical treatment circuit is accurate grinding or comminution, where the rock is crushed to produce small particles (<100 μm) consisting of individual mineral phases. These particles are then separated to remove gangue (rocks residues), thereafter followed by a process of physical liberation of the ore minerals from the rock. The process of liberation of copper ores depends upon whether they are oxide or sulfide ores. Subsequent steps depend on the nature of the ore containing the copper and what will be extracted. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plant. For sulfide ores, both secondary (supergene) and primary (hypogene), froth flotation is used to physically separate ore from gangue. For special native copper bearing ore bodies or sections of ore bodies rich in supergene native copper, this mineral can be recovered by a simple gravity circuit.
