changes in the metallurgical techniques for gold extraction since the introduction of the cyanide process (cyanide leaching or cyanidation) by McArthur and Forrester in 1887 [2]. A basic flowchart for the recovery of gold from its ore is provided in Figure 1. Figure 1 Basic flowchart for gold .
Introduction to Gold and Silver Leaching. The cyanide leaching process is the most important method ever developed for extracting gold from its ores. The early development of the process is attributed to a Scotchman, John Stewart Mac Arthur, in collaboration with the Forrest brothers. The method was introduced into South Africa in 1890.
Cyanide leaching: gold processing. ... Plants now also commonly inject oxygen into the leach tanks to help accelerate the leaching process. Since oxygen is a key component in the above reaction, it increases gold recovery for a given residence time in the leach tanks. ... South Africa is one of the worst polluters on the continent and the ...
CIL stands for carboninleach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks. CIL is slightly different from another gold extraction process called CIP or carboninpulp process.
Apr 25, 2018· Heap leaching is not that popular in South Africa because it is more applicable to shallow opencast mining, and South African gold mines are mostly underground operations.

installed in South Africa, Algeria, Italy, and Dubai. Additional modules Silver refinery Impure silver anodes are produced from the Minataur leach residue using a pyrometallurgical method and refined electrochemically to produce per cent pure silver. Any gold entrained in the feed is liberated by the process and returned to the gold refinery.
Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns.
