Gold Cyanidation Tests

d. Cyanidation: Before starting the cyanidation tests is important find out the lim

e necessary for the right pH. This can be done agitating the ore several minutes with lime until obtain a stable pH in the pulp.

Cyanidation test are done to different mesh size of grind and controlling the cyanidation time. It is very important control the free cyanide and pH. All the results obtained on recoveries and the time will give a recovery curve for a particular mesh size. Its comparison will be used for the analysis of the best conditions of cyanidation. It is important control the oxygen present in the slurry. This is a variable overlooked many times but is important for the cyanidation process because the rate of cyanidation can be modified.

e. Combining several processes.

It is important relate tests in order to define designs. Concentrates from flotation and gravimetry can be leaching and obtain a final recovery. Also, can be combined gravimetry with flotation, especially if there is free gold in a size that will not float. The possible combinations are a lot but with the results obtained in the first steps will be eliminated some combinations.
