GRAVITY CONCENTRATION OF GOLD FROM CYCLONE

2019-10-1 · In gold grinding circuits much of the free gold can lie in the finer size fractions and is amenable to concentration using enhanced gravity. Treating only a fraction of cyclone underflow means that much of the free gold will bypass the gravity concentration circuit and report straight to cyclone overflow. Treating even a

Gold gravity concentration by Knelson concentrator |

Gold has a specific gravity of 15.0 – 19.3, and a typical ore usually has a specific gravity of about 2.6 (e.g. quartz is 2.7, Pyrite 5.0, Magnetite 5.3 and Feldspar 2.6). Only free gold particles can be recovered by gravity concentration, particles should be liberated by crushing and grinding before gravity processing.

Minerals | Special Issue : Gravity Concentration

Gravity concentration is at present the main concentration process in the mineral industry in terms of tons processed. The size that can be processed ranges from very coarse materials, coarser than 100 mm, concentrated through heavy media vessels or ROM jigs, to very fine particles, about 10 microns, concentrated through centrifugal processes.
