Ore processing comprises the following steps: The first step is about crushing as well as grinding the gold ore. Experts add process water to make a slurry (a semi-liquid mixture). Then, experts add lime to the ore, whereas they mix cyanide solution with the slurry to filter the precious metals into the solution.

Galena Lead Ore Processing. Galena is kind of lead mineral with big density 7.4-7.6g/cm3 and gangue density of 2.2-3g/cm3. Its big embedded granule and density difference makes gravity a great beneficiation method to gain high grade galena concentrate. For gravity separation of galena, the separator involved is mainly jigger.
