Flotation is the most widely used method for the concentration of finegrained minerals. It takes advantage of the different physicochemical surface properties of mineralsin particular, their wettability, which can be a natural property or one artificially changed by chemical reagents.

Treatment of Platinum Flotation Products Johnson Matthey

An additional flotation recovery of platinum metals from the final hydrochlorination cakes enables the production of sufficiently rich concentrates ( 500 g t 1) with the mass of the initial material decreasing by up to three times. The concentrates then be returned to the roasting stage of the flowsheet.

Further, because optimum moly flotation pH is at 78 while optimum copper selectivity is typically in the 911 pH range, use of a moly collector in bulk flotation can improve floatability. Some mines find that the moly collectors can have a negative impact on copper flotation so testing and evaluation must be conducted to find the optimum moly collector hydrocarbon and frother products.
