Due to the different ore properties, the dosage range of flotation reagent is also different. Even for the same type of ore, there are also some differences in the formation of ore deposit, so the content of useful minerals and gangue vary, and the dosage of flotation reagent required in the flotation process
flotation. FLOTATION PROCESS Flotation is a method of separating an ore species froth another, based on its hydrophobic surface characteristics either natural or induced when present as a suspension in water with air bubble. Due to the affinity of the desired mineral to adhere to air bubbles it is floated out of the ore

Apr 11, 2019 Xanthate Application in Copper Froth Flotation. In the flotation process of copper ore, xanthate mainly reacts with Cu2. Therefore, when processing minerals containing more Cu2 on the surface, the effect of xanthate is stronger, and the order of its action is Cu2S CuS Cu5FeS4 CuFeS2. 4. Xanthate Application in Galena Froth Flotation.
Jun 05, 2019 Abstract Reagent dosage setting is closely related to the product quality and economic benefit of an iron ore flotation process. The strong nonlinearities, uncertainties and coupling of the flotation process make it difficult to set proper reagent dosage. In this paper, a reagent dosage intelligent optimal setting method based on case-based reasoning CBR is put forward.
May 01, 2014 The new process is environmentally friendly, as only well-known household reagents are used oleic acid or tall oil, dextrin, sodium hydroxide and magnesium chloride at pH 10.5. The Sydvaranger magnetite mine closed in 1996 due to low iron ore prices and was reopened in 2009.
