Flsmidth has secured a dkk350 million order to supply key mineral processing equipment, including flotation technology, screens and cyclones, for a new concentrator at a polyus gold mine. the flsmidth order, which covers the entire process flowsheet, features a ball mill, flotation technology, thickening, gravity gold concentrators, cil (carbon.

Thus, the process relies on the buoyancy induced by adding air to a suspension of flocculated water, which drives the floc–bubble aggregates to the top of the daf reactor towards the flotation layer, while the clarified water is withdrawn at the bottom of the daf reactor (bratby amp; marais 1977; lazaridis et al. 1992).

Ff cc tt, and multiplying (f c t) by t gives us: ft ct tt, so subtracting this equation from the previous eliminates t and gives: f(f t) c(c t), and rearranging produces the equation for the ratio of concentration: fc (c – t)(f – t).

Flotation cell is widely used for separating nonferrous metal, black metal, noble metal, nonmetal mineral, raw body and materials of chemical industry, which are subject to coarse separation, swept separation, fine separation and flotation, so the useful ore are is a high technological enterprise that integrated research , manufacture, sales and service .

Flotation has the capacity to recover at different mineral species at different stages in the process. in this way we can beneficiate complex mixtures of ores, to produce a range of different mineral products. to illustrate the power of the flotation process, consider this sample of low grade copper rock.
