Treatment of Gold Tailings in High Rate Thickeners

Degradation of cyanide occurs in the tailings water discharge to slimes dams. The degree of degradation or cyanide loss in the water recovered depends on a number of factors, but is usually assumed to be about 90%. The most important mechanisms of CN loss are through HCN losses and oxidation by oxygen in the air, which also assists in the hydrolysis of CN. These mechanisms are supported by the ...

Prospecting Gold Tailing Piles with a Metal Detector

This is not theory, this is a fact. Some seriously nice nuggets are being found every year in these old dredge tailings.
