Gold Mining Process Development – Denver Mineral Engineers

The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation.

gold ore dressing equipment,gold mine,removal rate of the ...

During the impurity removal process of gold ore dressing equipment, the faster the lime water is added, the lower the recovery rate of the gold mine. Generally, control the lime water speed at the beginning of 3-5ml/min, and finally 1-2ml/min, this effect It is best to add about 80ml of lime water and 24 grams of industrial lime to neutralize to PH=6.7. The neutralization time is about 35 minutes.
