How to Leach Gold Ore With Chlorination | Sciencing

Apr 25, 2017· Grind the ore so that all parts of the ore are open to the HCL mixture. Add your ore to a plastic-tub cement mixer along with 10 pounds of river rock and turn the mixer until the ore is 200 mesh or more. 200 mesh means there are at least 200 particles in one square inch of ore.

Mineral processing Wikipedia

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
