Processing Materials: Gold mining gravity separation is the most effective and economical method which used for recovering coarse-grained single gold in advance by using jig, chute and shakers, so as to facilitate subsequent flotation or cyanidation operation. It is mainly suitable for sorting placer gold. The particle size of placer gold is generally greater than 16t/m3 with large density difference with gangue.
Common Characteristics of Gold Mining Gravity Separation
(1) There must be a density difference between gold ore particles
(2) The separation process is carried out in the moving medium
(3) Under the combined action of gravity, fluid power, and other mechanical forces, the gold ore particles are loose and stratified according to the density
(4) The layered materials can be separated under the action of moving medium, and obtain different final products.
Working Principle of Gold Mining Gravity Separation
(1) The sedimentation principle of particles and particle clusters (heavy medium)
(2) The principle of particle clusters stratified by density (jigging)
(3) The principle of particle clusters stratification in the revolving flow (cyclone)
(4) The separation principle of particle group in inclined plane flow (spiral chute)
(5) Stokes formula
