form of water-based slurry) is transported to the flotation circuit where the copper sulfide ore minerals are concentrated and separated from the nonmineralized material by a series of rougher (see fig. 3) and cleaner flotation cells, which produce successively higher grade concentrates. This flotation slurry, also

Titan Copper Flotation Circuit Titan, working closely with the customer's engineering firm, designed and fabricated a flotation circuit for treating copper. Scope of work included fabrication of ten 180 cu. ft. Titan open-flow flotation cells and twenty 100 cu. ft. Titan cell-to-cell flotation cells including support platforms and launders.
