    The best result of the campaign was achieved with the first Hybrid Flotation test, which produced a sulfur content of 0.31 % associated with a 96 % Fe output. This result represents an overachievement of the targets for the test campaign. The second Hybrid Flotation test only reduced the sulfur content to 0.75 %

    Sep 01, 2011· Withflotationconcentrates containing less than 70% elementalsulfur, it is difficult to obtain a fluid melt in the subsequent melting and filtration steps. Theflotationconcentrate is dried to less than 15% moisture as high moisture concentrates may cause foaming in subsequent melting steps (Chalkley et al., 1993). 2.4

    2. FrothFlotation+ Concentrate Thiourea Leaching. For vein gold ore with high arsenic andsulfuror high carbon argillaceous, the gold sulfide concentrate can be obtained by the frothflotation, and then theflotationconcentrate can be recovered by the thiourea leaching process. Thiourea gold extraction is a kind of increasingly

    As an important indicator offlotationperformance, froth texture is believed to be related to operational condition insulphur flotation process. A novel fault detection method based on froth texture unit distribution (TUD) is proposed to recognize the fault condition of sulphurflotationin real time. The froth texture unit number is calculated based on texture spectrum, and the probability
