Nickel Ore Lab Beneficiation and Equipment
In this process, chemicals (reagents) are added to the ground ore slurry to selectively adhere to nickel minerals, causing them to float to the surface. Process Steps: Addition of Reagents: Add collectors, frothers, and modifiers to the slurry. Agitation: The slurry is agitated, creating bubbles that capture the nickel minerals.

What Is The Difference Between Clarifier And Classifier
Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). Rise rate parametrizes the area required to recover the design flow or solids loading, the design dry tonnage.

Rake Classifier
rake classifier mechanism. The rake classifier (Figure 9.18(a)) uses rakes actuated by an eccentric motion, which causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated. The settled material is thus slowly moved up the incline to the discharge.
