    Processing. The processing of gold ore involves crushing, treatment with chemicals, melting (smelting) and further purification. It is then poured into moulds where it cools and hardens as gold bars called 'bullion', which make the gold easy to stack and transport. The first stage of processing gold ore is crushing.Blasting, crushing, and grinding are necessary to liberate the gold for recovery. Hard rock gold deposits have three sub classes free milling, sulfide associated and refractory. Free Milling Gold. Gold ore is considered free milling when it is easily liberated by grinding and separated from the other minerals.
