2.1 Microwave pre- treatment of refractory gold ores . Most of refractory gold occurs within sulphide minerals such as FeS 2 and FeAsS and are treated by roasting, pressure leaching or bacterial leaching to render the gold amenable to recovery by subsequent treatment techniques (Haque, 1987).
They promote: i) the oxidation of the sulphide matrix, rendering gold more accessible to the leaching solution; ii) gold stabilisation, a result of the formation of gold-rich complexes and/or colloids; and iii) gold solubilisation by enhancing the permeability of ore bodies (Amachi, 2008; Brehm et al., 2005; Burford et al., 2003; Hilson and ...
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.

Following crushing through a jaw crusher, the ore is fed into the semi autogenous grinding (SAG) mill along with water and steel balls. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself.
Calaverite is a telluride mineral that's really special because it's packed with gold. It's not just a rock with a little bit of gold; it has a lot of it, making it pretty unique. In calaverite, gold isn't just a tiny part – it makes up about 42% of the mineral. This means that calaverite is almost half made of pure gold.
