The gold processing industry is a large consumer of lime reagents in various forms. Its role in gold processing is mainly as a pH control agent for optimal cyanidation leaching of gold, as well as a neutralization agent in refractory gold processing via acidic oxidation routes. There are, however, a range of conditions upstream of cyanidation ...

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption …
Gold ore processing plants are common including washing & screening, crushing & grinding, beneficiation, concentrating, drying or smelting. 1. Washing & screening: It is mainly to remove the mud in the placer gold ore, or to make the particle size meet the requirements of the sorting operation. 2. Crushing & grinding: The content of gold in the ...
Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This …
