Rock Gold Processing: On the other hand, processing rock gold begins with physically breaking down the ore by crushing it, sometimes in several steps, to get it ready for separating. Just like with alluvial gold, after we prepare it at the start, the ore taken from quartz veins or other hard rock spots goes through:

Gold deposits are formed via a very wide variety of geological processes. Deposits are classified as primary, alluvial or placerdeposits, or residual or laterite deposits. Often a deposit will contain a mixture of all three types of ore. Figure 1. High-grade (bonanza) gold ore, brecciated quartz-adularia rhyolite.
