68 ADVANCES IN GOLD AND SILVER PROCESSING increased to 50 kg per tonne. Highly refractory ores might require over 100 kg per tonne to yield more than 83 per cent gold by cyanidation. Sawyer and Hendrix (1988) had investigated the effect of sodium hypochlorite on the gold extraction from a carbonaceous ore in Nevada by heap leaching.

Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.

[PDF]The Cyanide Handbook: Gold Ore Processing & Metal ...

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 ...
