Gold and Copper Processing Methods for . - Wikinvest

Gold is extracted from naturally-oxidized ores by either heap leaching or milling, depending on the amount of gold contained in the ore, the amenability of the ore to treatment and related capital and operating costs. Higher grade oxide ores are generally processed through mills, where the ore is ground into a fine powder.
