七、有色金属和贵金属部分富集难选原料的化学冶金方法 D. N. Abishev (苏联哈萨克科学院化学冶金研究所) 根据对难选矿石中较有用成分物理化学性质的理论研究和试验,制定出含黄铁矿的多金属物料、含铜和含钼的矿石及中间产品的热磁分选法;混合和氧化的有色金属矿的热液和电化硫化法;石英优先分选法和疏水性矿物的球团法。这些方法都是基于把矿物直接转变,形成不同性质的新合成相,如此
Chemical and Metallurgical Methods for Enriching Hard to Choose Raw Materials by Nonferrous Metals and Precious Metals DN Abishev (Institute of Chemical Metallurgy, Kazakh Academy of Sciences, U.S.) Based on theoretical and experimental studies on physicochemical properties of more useful components in refractory ores, Polymetallic materials for mines, thermal and magnetic separation processes for ores and intermediates containing copper and molybdenum; hydrothermal and electrochemical sulfidation processes for mixed and oxidized non-ferrous metal ores; quartz priority sorting and hydrophobic mineral pellets law. These methods are based on the direct transformation of minerals to form new synthetic phases of different properties, and so on
