Jan 13, 2013· Leaching of copper malachite in sulfuric acid after it has been crashed to about 5mm. The leaching started with a manual agitation process in a square vessel, however that proved somewhat cumbersome.
Leaching is the first prerequisite of any hydrometallurgical process. Solutions containing ammonia may allow for selective leaching of the copper from the ore. In this study, the leaching kinetics of malachite, which is an oxidized copper ore, in ammonium nitrate solutions was examined.

Malachite: Malachite mineral information and data. Malachite is a green, very common secondary copper mineral with a widely variable habit. Typically it is found as crystalline aggregates or crusts, often banded in appearance, like agates. It is also often found as botryoidal clusters of radiating crystals, and as mammillary aggregates as well.

In the operations, leaching of the ore, stripping of HCN and absorption of the HCN, countercurrent techniques, long known to the mining industry, are usually but not necessarily used. In the leaching operation a shorttime, under an hour, is adequate for solution of copper by the cyanide.
There have been examples where froth flotation was used to concentrate malachite. In general froth flotation is not used to concentrate copper oxide ores, as the cost of leaching is cheap when compared to the cost of grinding . Read More; Mining Heap Leach Mining Copper SX/EW Mining Process SENET

method is leaching, which involves a chemical reaction between copper oxide and a leaching medium. Leaching can be divided into two types, namely, acid leaching and ammonia leaching [7,8], named after the leaching agent employed.
In the present work, a chemical process was developed to produce copper sulfate pentahydrate from the malachite ore. We demonstrated that it is possible to recover the copper incorporated in the malachite with a dissolution percentage 99%.
