Gold Ore Crusher Machine. Gold ore is extracted from some mines as part of the process of mining and refining other metals like copper. During those operations, gold is refined to an acceptable purity as part of the gold production process. In order to extract gold, the first important step is to process the ores using gold ore processing plant.
The CIL process is viable if there is sufficient gold content, carbonates/clays in the ore which will "rob" some gold in solution, and it leaches in 813 hours. A Stainless Steel Cathode from the electrowinning cell in the gold room. Notice the gold that has plated onto the surface of the stainless steel mesh.
