Whenever gold carriers are targeted, the benefits are generally higher, as is the cost of the gravity circuit. These applications include preconcentration (although this is more commonly achieved with flotation; see Chapter 20) and scavenging of gold carriers.A discussion on the use of gravity instead of flotation for preconcentration is included in …

Highlights Worldwide gold recovery on activated carbon grew from zero to almost 70% in twenty years from 1980. The stellar attributes of carbon gold plants led to complacency in the industry in designing and operating these plants. Most CIP and CIL plants are overdesigned and operated sub-optimally. Optimum design criteria and …

The roasting cost works out at approximately $1.22 per ton of concentrate, distributed as shown in Table 99. At MacLeod Cockshutt Gold Mines, Ltd., the cost of roasting in 1941- 1942 was 32 cents per ton milled or $1.25 per ton of ore roasted, while at Lake Shore mines for the same year the cost was about 80 cents per ton roasted.

However, many sites have pyrite and/or chalcopyrite. The gold is embedded in the ore in very fine particle sizes. That is not amenable to grinding using ball mills followed by gravity separation methods such as sluices or cyclonic concentrations. Consequently, there is a need for simple low-cost methods for leaching gold from sulfide-based ores.

Plants accumulating more than 1 mg kg −1 of gold are considered as hyperaccumulators; this limit is based on the normal gold concentration in plants of 0.01 mg kg −1 (Sheoran et al., 2013). Plants do not normally accumulate gold due to the low solubility of gold in most soils.

Generally base metal ore tailings have low concentration of gold. Tailings with less than 1 mg/kg gold are unlikely to have sufficient gold to justify economic phytoextraction. A higher gold grade of the tailings will yield a higher gold concentration in the plant thus allows for an economic recovery of the same (Wilson-Corral et al., 2011).
