Gold processing involves the extraction of gold from its ore, which is typically found in rocks and minerals. The process begins with crushing the ore to release the gold particles, followed by grinding to further reduce the size. Various methods, such as cyanidation or gravity separation, are then used to separate the gold from other materials. After extraction, the gold is refined to remove impurities. This can be done through processes like electrolysis or smelting, which involve heating the gold to high temperatures. The final product is pure gold, ready for use in jewelry, electronics, and investment.
