Gravity separation: This method utilizes the differences in density between nickel minerals and gangue minerals. Techniques such as jigging, shaking tables, or spirals are used to separate the heavy nickel-bearing particles from the lighter gangue material.

Unlike nickel sulphide ore, the distribution of nickel metal in nickel laterite is distributed uniformly and act as interstitial condition in molecular lattice of particles. It makes the concentration process of nickel through flotation and gravity separation can not be applied.

The method combines mechanical ore dressing and low-temperature selective reduction to separate nickel and molybdenum from nickel-molybdenum ore. The nickel-molybdenum ore contains about 2 percent of nickel and about 2 percent of molybdenum, and is a well-known refractory mineral. The invention can obtain two furnace charges by the enrichment and …
