whole ore leaching impractical or uneconomic. The ultra-fine gold particles associated with sulfide minerals are often too small to recover by gravity and very expensive to liberate by grinding. Typically, sulfide-associated gold is recovered by froth flotation. A typical sulfide-associated gold flowsheet is presented below in Figure 2:
Relatively fine grinding media initially led to reduced particle size reduction but, for prolonged grinding, enabled attainment of a smaller product size. This is thought to be due to the smaller interstitial space between media particles, which are generally much larger than the size of product particles.
