原始语种摘要: Abstract(#br)Selective separation of pyrite from base minerals is very important and challenging. This research investigates the combined inhibitory effect of two novel reagents on flotation behaviors of pyrite and galena under the low alkaline conditions. The depression and adsorption mechanism of calcium hypochlorite [Ca(ClO) 2 ] and dextrin (DX) on pyrite and galena were systematically studied via the microflotation experiments, reagent adsorption measurements and X-ray photoelectron spectroscopy. Flotation results showed that the combined effect of Ca(ClO) 2 and DX depressed the flotation of pyrite more strongly than that of their individual effect. An improved recovery difference of more than 60% between the galena and pyrite was achieved at pH 10 while using Ca(ClO) 2 and DX as...
