sulphide minerals roasting machinary

In situ roasting and leaching of sulfide minerals
There is provided a process for recovery of metal values from an ore body containing sulfide minerals. The ore body is fractured for increasing its permeability. The fractured ore body is then roasted in situ to increase the permeability and porosity of ore body to liquid leach solutions. The roasted sulfide minerals in the ore body are thereafter contacted with a leach solution to extract Get Price

Roasting of Sulfide Minerals
2016 2 10   Summary. In addition to common metals like copper, lead, zinc, and nickel, a number of other metals such as antimony, bismuth, cadmium, cobalt, mercury, and molybdenum occur as sulfide minerals. In the extraction of metals from sulfides, roasting is applied to achieve different objectives depending on the overall process flow sheet. Get Price
