Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
I know of a placer gold mine with an average grade is 0.3 ppm (0.3 gram/tonne) and the reserve is 30 million tons. The mine located in remote area and we do not have sufficient water although we send a sample for Knelson company but the max recovery was obtained 32%. I am looking for a new method
A motorized dry-washing machine is excellent for the production demands of a one or two-person operation. Under ideal conditions, it is able to process up to about a ton of raw material per hour, which is the equivalent of what a medium-sized wet sluicing operation can produce.

Table I and Table II illustrate the capital and operating cost breakdowns for a typical South African gold plant. These figures are not a standard but reflect the nature of the ore and the design basis for a …
Gold readily dissolves in these solvents because of the formation of complex ions that are very stable. Gold (Au) melts at a temperature of 1,064° C (1,947° F). Its relatively high density (19.3 grams per cubic centimetre) has made it amenable to recovery by placer mining and gravity concentration techniques.
Gold Washing and Gravity Circuit for Processing Placer Gold The handling of large quantities of gold-bearing gravels is of utmost importance for most successful placer operations. In addition to providing efficient washing and recovery methods, the placer plant should be constructed as a compact unit that can be readily moved.

Oct 20, 2014· Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.
