Chemical Separation For Gold
Gravity Separation: Highly Effective Tool for Gold-Bearing …
The gold-bearing ore chemical composition plays a key role in the gold recovery efficiency of cyanidation process impacting the slag's one [17,18,19]. The results obtained when the gravity separation was used might be explained by the fact that the specific gravity of grounded material depends on its chemical composition.
