The cyanide leaching of tellurides has a history of controversy, with some researchers maintaining that successful gold extraction could be achieved provided that certain conditions were met. Operationally, plant leaching proved to be not as successful as in the laboratory and certainly was not as robust as the leaching of free gold.

2015-8-24 To make gold soluble sodium cyanide (NaCN) is added and the cyanide ion forms a complex ion with the gold. This complex ion, [Au(CN)2]-, is readily soluble. Issues of gold extraction using cyanide: Cyanide is toxic to animal and plant life and may cause death if exposed to high enough doses. Free cyanide is cyanide ion (CN-) and hydrogen ...

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. The pad collects the now metal-impregnated solution which is stripped of gold and resprayed on the heap until the ore

2016-6-14 Figure 1.2 Schematic diagram showing gold extraction The ore is then combined with either sodium cyanide or calcium cyanide. Oxygen must be bubbled up through the pulp for the dissolution of the gold to occur. The cyanide anions release the gold’s cations, oxidizing the gold and making a soluble aurocyanide metallic complex, NaAu (CN)2.

2021-5-27 Cyanide gold processes can be divided into stirring cyanide and percolation cyanide. Stirring cyanide is used to process tailings or complement full mud cyanidation after gravity, mercury mixing and flotation of gold concentrates. Percolation cyanide is used to treat flotation tailings and heap leaching of low-grade gold ore.

2018-10-19 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. MacArthur, and William Forrest.

2020-5-16Here I present an Process EXAMPLE of Gold Extraction Cyanide in which the cyanidation feed consists of a pyrite concentrate floated after the selective flotation of a copper-gold concentrate. The pyrite concentrate is reground to 90 minus 325 mesh and aerated in a high-lime solution prior to cyanidation. It contains 99 sulphides of which 10 to 20 percent is pyrrhotite and 0.3 to 0.7
