Cyanide Use in Gold Mining Earthworks

How is cyanide used in mining? A sodium cyanide solution is commonly used to leach gold from ore. There are two types of leaching: Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold from the ore into the solution as it trickles through the heap.

Cyanide Process Gold Cyanidation Process Gold

Cyanide process is also called as Macarthur-forest Process. It is the process of extracting gold or silver from the ores by dissolving in a dilute solution of potassium cyanide or sodium cyanide. This process was introduced in the year 1887 by the Scottish chemists naming Robert W. Forrest, John S.

Cyanide hazards to plants and animals from gold

Cyanide extraction of gold through milling of high-grade ores and heap leaching of low-grade ores requires cycling of millions of liters of alkaline water containing high concentrations of potentially toxic sodium cyanide (NaCN), free cyanide, and metal-cyanide complexes. Some milling operations result in tailings ponds of 150 ha and larger.

Cyanide and removal options from effluents in gold

2013-9-1  The SO 2 /Air process offers an effective means to treat gold mill effluents and to produce effluents containing concentrations of less than 0.5 mg/L for total cyanide and for each of the metals commonly found in gold mill effluents (e.g., copper, iron, nickel and zinc). The process can be applied to either aqueous reclaim water or directly to the tailings slurry.
