Gold Tailings Reprocessing Technology - xinhaiepc

In general, the gold recovery method of gold tailings is mainly the all-slime cyanidation CIP method. It is the recovery of residual gold particles from tailings by using the property of gold soluble in cyanide. The gold recovery for large capacity and low-grade gold tailings is common heap leaching.

Recovering Cyanide From Gold Plant Tailings

An important consideration when evaluating process options for the treatment of the gold or silver plant tailings for cyanide recovery, is whether to treat the tailings directly as a slurry, or to first separate the solids and liquids and treat only the liquid phase. In making this decision, the following factors must be taken into consideration:• The cost of solid/liquid separation. If the solids and liquids have already been separated (in Merrill Crowe or heap leaching, for example) this is not a factor. If they have not been separated, the cost of solid/liquid separation must be included as part of the cost to recover cyanide,

Economical dewatering of tailings for mine backfill with ...

The treatment of tailings and paste from ore processing filtration and dewatering is becoming increasingly important. Firstly, the recovery of water from the process reduces the input of an important resource – water. This can make the difference between ‘yes, we can operate’ or ‘no, we cannot’. Secondly, the filtered tailings can be dry-stacked, which is safer, cheaper, and environmentally more acceptable. Thirdly, especially with
