Gravity Concentration an overview ScienceDirect Topics. For low gravity solids with a specific gravity of 2.6 and a barite specific gravity of 4.2, the equation to determine the low gravity concentration V lg is V l g 6.25 2.0 V S 7.5 MW where V lg is the volume percent of total suspended solids, and MW is the mud weight in ppg.

Mar 21, 2021 Particles are classifi ed based on their specific density difference in gravity concentration. 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.
Stage 2 Milling--Grind particles to very small or powder.Usually use wet pan mill or ball mill. Stage 3 Gravity separation or Flotation separation. If it is oxide gold ore,use gravity separation method. if it is sulphide gold ore,use flotation separation method or CIP method.
