用红外光谱分析和电子能谱分析研究了Na_2S_2O_3和CuSO_4与黄铜矿的相互作用。结果表明,Na_2S_2O_3和CuSO_4反应产物呈化学吸附固着在黄铜矿表面,Na_2S_2O_3和CuSO_4可代替剧毒的氰化物作Mo及Cu-Mo矿石浮选时铜矿物的抑制剂。浮选研究表明,用这种抑制剂取得良好效果。
The interaction of chalcopyrite with Na_2S_2O_3 and CuSO_4 has been studied byanalyses of infra-red spectra and electron spectroscope. Experimental results showedthat the reaction product of Na_2S_2O_3 and CuSO_4 attaches to the surface over chal-copyrite grains by chemical adsorption. A severe toxic cyanide, therefore, maybe replaced by Na_2S_2O_3 and CuSO_4 in the flotation of Mo or Cu-Mo ore actingfavourably as depressor of Cu containing mineral.
