Outotec 3300m forced air tank flotation cells are currently utilized in the rougher flotation circuit at the Copperton concentrator. Higher overall recoveries have been observed on the newer Outotec tank cells compared to the original 85m3 self-aspirated flotation cells they replaced. However, coarse particle flotation response on these
ABSTRACT. The operational proof-of-concept for the flotation cell class of 500 m3 and larger is discussed in this paper. Two different sites are used as case studies and …
— The ore is mined from an open pit, crushed, and fed to ten ball mills. The concentrator is divided into two parallel comminution-flotation sections, so that five ball mills feed each flotation section. Both sections consist of three bulk copper and molybdenum rougher flotation lines, and the rougher concentrate is transferred to a regrinding stage.
— The antimonite ore has a strategic importance and is contained in group of non-ferrous metals. Sulfide and oxide components are used in non-metal sectors (paint, paper, plastic, etc.), while they ...
Since 2019 Concentrator advanced from Wemco flotation cells to tank flotation cells. The final milled product at 80% passing 0.15 mm is fed to the Tankcells Flotation Plant (TFP) with capacity of 1 745 t/hr, which is a counter-current circuit, where the copper is concentrated into the overflow of the rougher, cleaner and re-cleaner flotation stages.
