Determine Total Cyanide in Solution
· Experience has shown that the length of time required for complete dissolution of the gold varies depending on the type of cyanidation circuit in use. Thus the solution for mills where the whole ore is cyanided will normally dissolve the goldleaf in from 0,5 to hr, while solutions from mills where a concentrate is cyanided will require from 1 hr up to as long as 1215 hr.

How is Sodium Cyanide Consumed during Gold Cyanidation ...
· Sodium cyanide is the most commonly used leaching chemical in gold extraction process. According to theoretical calculation, leaching 1 gram of gold only requires grams of sodium cyanide. However, in most gold cyanidation plants, the consumption of cyanide is high, which is 50100 times higher than the theoretical calculation.
