  • How to Leach Gold Ore With Chlorination Sciencing

    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.
