In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the goldbearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore ...

Gold ore extracted from mines in the earth contains a significant amount of impurities, including traces of other metals. In order to separate the gold from other metals, chemicals such as cyanide solution or mercury are introduced to the gold. This process causes the gold to coagulate, and form nuggets and clumps of gold.

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 page offers a comparative review of gold recovery ...
