The ongoing depletion of gold and silver-containing ore deposits demands a shift towards the processing of more complex sources. Leaching of gold or silver from these sources, which are named refractory and are typically low-grade, can be complicated due to one or more of the following effects: (1) kinetic or thermodynamic impediments on cyanide diffusion or on the …

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.

The size analysis of a gold bearing ore crushed in a jaw crusher indicated that 80% passed through a 3000 micron sieve. Further size reduction was completed in a 1.0 xx1.5m wet ball mill rotating at 78 % of the critical speed to liberate the gold. Determine the maximum size of the balls at the ommencement of grinding. Data: S.G. of the ore =3.86.
