Gravity Separation Of Nickel Laterite Ore

To prepare nickel laterite ore for selective reduction of its nonferrous metal oxides, it is comminuted preferably to 85 minus 200 mesh and is mixed with comminuted preferably 100 minus 65 mesh high volatile, high ash waste coal and a non-gaseous sulfur materialarbon content of the coal is 50 to 150 of the amount of carbon needed for stoichiometric complete reduction of nonferrous.
