Abstract
About 60 per cent of magnesite ores of Haicheng Magnesium Mine, due to their low grade, are not currently commercially exploitable. In this paper, the flotabilities of the main component minerals of the ores were studied in detail with ether amine as collector. Based on. these, a new technique of reverse-direct flotation with single etheramine as collector for the beneficiation of the ores was developed. It gave highly satisfactory results. On the basis of the calculation by means of CNDO/2 method, of the studies of the solution chemistry of magnesite and of the adsorption tests and Zeta-potential measurements, the key mechanism in the new technique about activating effect of Ca2+ on the flotation of magnesite was suggested.
