Gravity Beneficiation Concentration Iron Ore Extraction and beneficiation of ores and minerals5451424 gravity concentration although gravity concentration was once widely used in the beneficiation of iron ores, less than 1 percent of total domestic iron ore was beneficiated using this method by the early 1990s see table 1-4 Read More
As the particles are exposed to gravitational energy whilst in suspension within the water, those with a higher specific gravity (density) settle faster than those with a lower count, resulting in a concentration of material with higher density at the bottom, on the jig bed The particles are now concentrated according to density and can be .
Concentration in this typical case starts at about 10 mesh and continues on into the minus 200 mesh fin Gravity concentration starting as coarse as possible is very important in the recovery of a mixed ore of rutile and ilmenite, for a granular slime free product is much more amenable to subsequent magnetic and electrostatic separation
