For example, complex gold in a sulphide complex of pyrite, must isolate a specific gravity of 19.3 for gold from 5.2 for pyrite. Using gravity to recover minerals in their coarsest fraction minimises over-grinding and prevents losses due to excessive comminution, and during multiple processing steps.

Mar 24, 2021 Deliver. Since the 1980s, the Gold Technology Group has run the Amira P420 series of Gold Processing Technology Projects. Initially, the projects were laboratory based and focused on understanding the fundamentals of leach and adsorption circuits. This knowledge was then applied practically in studies designed to optimise circuit performance.
Feb 29, 2016 The difference between the specific gravity of gold 19.0 and the low specific gravity of the gangue 2.7 makes gravity concentration the primary means of recovery free gold particles. In general, gravity separation has some advantages over flotation and leaching, it needs significant lower capital investment, less power and low handling costs.
