Gold appears in the effluent soon after the first trace of cyanide is noted. Thiocyanates, the main source of cyanide loss, are stable compounds, but although they build up in solutions, they do not affect extraction. Low alkalinity is favored, a pH of 9.6 to 10.2 giving the best extraction. A cyanide of 49 per cent NaCN equivalent is used.

Dump leaching is an industrial process to extract precious metals and copper from ores.. Dump leaching is similar to heap leaching, however in the case of dump leaching ore is taken directly from the mine and stacked on the leach pad without crushing where, in the case of gold and silver, the dump is irrigated with a dilute cyanide solution that percolates through the ore to dissolve gold and

Artisanal and Small-Scale Gold Mining Without Mercury. In many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant

The H2O2 kills the cyanide slowly (and heats the solution at the same time) and the solution is only used for one batch of parts. I would guess you would generate about 4 gallon of cyanide waste solution per 20kg of material. That includes the spent make up solution plus rinses. Gold in NaCN/H2O2 will zinc out fairly easily.

The cyanide solution strength is also important in leaching gold, with the typical range of solution being in the 0.02% -0.05% NaCN. The gold particle size has a tremendous effect on the time required for dissolution in a cyanide solution. Generally, the finer the gold, the quicker it will dissolve. A 45 micron particle of gold would dissolve

Sodium cyanide is the most commonly used leaching chemical in gold extraction process. According to theoretical calculation, leaching 1 gram of gold only requires 0.5 grams of sodium cyanide. However, in most gold cyanidation plants, the consumption of cyanide is high, which is 50-100 times higher than the theoretical calculation.
