Bulk (Copper-Moly) Flotation . Both the copper and moly sulfide ores together (bulk) float in rougher flotation cells, then cleaner column cells, and often scavenger cells. These groups of flotation cells work together to give a high total yield of the bulk ore, which is sent on to be thickened. Tailings (Gangue) Thickening / Dewatering
Mineral processing - Mineral processing - Dewatering: Concentrates and tailings produced by the methods outlined above must be dewatered in order to convert the pulps to a transportable state. In addition, the water can be recycled into the existing water circuits of the processing plant, greatly reducing the demand for expensive fresh water. Filtration is the separation of a suspension into a ...

The ore, ranging from 60-65% silica, with pyrite, arsenopyrite, and calcite with 3 to 4% copper.
Table 1: Grade/recovery performance of a hypothetical copper ore flotation process. Product % Weight % Cu Assay Feed 100 2.09 Concentrate 10 20.0 Tailings 90 0.1 (a) From Table 1, the Ratio of Concentration can be calculated as F/C = 100/10 = 10. If only assays are available, the ratio of concentration equals (20 – 0.1)/(2.09 – 0.1) = 10 ...
Fig. 4. Copper extractions from the copper smelter slag and the copper smelter slag flotation tailings as a function of time at different initial ferric iron concentrations By comparing Figure 2 and 4, it can be seen that both the copper extractions and the copper dissolution curves were similar in sulphuric acid alone and in the presence

Aqueous slurries' dewatering using gravity-driven thickeners is an essential unit operation in mineral processing. Thickener feed dilution is often used for enhanced flocculation and sediment compressibility. This work investigated the effect of feed dilution on thickener performance for copper flotation tailings.
The proposed process includes crushing and grinding of the mineral, bulk copper-molybdenum rougher and cleaner flotation, regrinding, copper-molybdenum separation, molybdenum flotation, and dewatering of copper and molybdenum concentrates. The flotation tailings would be thickened to 72% solids before placement in a tailings storage facility.
