Leaching Low-Grade Gold Ores | SpringerLink
Multistage agitation leaching followed by elaborate solids-liquid separation is required to recover most of the gold (up to approximately 95%) in solution, in a reasonably short time (see Chapter 4). Large tonnage of a relatively high-gold-content ore is a prerequisite for the substantial capital and operating costs required for milling.
