Flotation separation of copper–molybdenum sulfides

2015-11-1  The yield of molybdenum-bearing copper concentrate was too low in each batch flotation to carry out the copper–molybdenum separation because of the low grade (0.90% Cu and 0.056% Mo) of the ore. Therefore, the molybdenum-bearing copper concentrates from different batches were blended together to obtain sufficient sample for copper–molybdenum separation.

FLOTATION

Flotation is a process in Liquid-Solid Separation technology whereby solids in suspension are recovered by their attachment to gas (usually air) bubbles, usually with objective of removing the solids from the liquid. The particles most effectively removed are in the size range from 10 to 200 μm. The particle-bubble aggregates that are formed have a density less than the suspension itself ...
