Flotation of nickel-copper sulphide ore : optimisation of process …
Froth flotation is widely used for concentration of base metal sulphide minerals in complex ores. One of the major challenges faced by flotation of these ores is the ever varying grade and mineralogy. This therefore calls for a continual characterisation and optimisation of flotation parameters such that concentrator performance as a whole is always maintained. In this …

How to Process Copper Lead Zinc Ore with Gold and Silver by Flotation
A further separation of the lead-copper into their respective products by flotation is often economically advantageous if the crude ore contains 0.8% copper (16 pounds per ton) or more. In the case of this study, it is assumed that a separate lead-copper circuit is not warranted. The flotation section consists of two 10-cell "Sub-A ...
