Warman® AHF froth pump case study | Weir Group

More Case Studies. When South African phosphate producer Foskor needed to pump viscous non-Newtonian thickener underflow slurry, the Weir Minerals team was up to the challenge. Since the 1980s Foskor had used Envirotech® B-frame slurry pumps, but now required a specialised solution better suited to extremely viscous materials. After achieving success with Warman® AHF froth and paste pumps …

is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the .

 · c the pulp containing the minerals is then pumped to a flotation plant where the minerals of economic importance are separated by means of three metallurgical processes, namely, a froth flotation process, a magnetic concentration step and a gravity separation process d the product from these processes are various concentrates.

Certain sections are used for wet grinding marginal ore to below 0.3mm, followed by a copper flotation process similar to that used for the underground ore. Concentrate is pumped to the dewatering plant, while magnetite is removed from the tailings before thickening and pumping final product to Foskor for phosphate flotation.
