摘要
吸附试验结果表明：硫酸铵活化孔雀石浮选，是通过提高吸附黄药能力来实现的在孔雀石－黄药浮选体系中加入硫酸铵，可大幅度提高黄药的吸附量和吸附速度，饱和吸附量提高了１倍，吸附速度常数由０５６提高到１０１６，可见硫酸铵对黄药在矿物表面的吸附起了“促进吸附”
The activating results of malachite by the use of ammonium shulplate,which can promote xanthate adsorption on malachite,are obtained In the system of malachite-xanthate,the amount of adsorption of xanthate on malachite increased greantly with the addition of ammonium sulphate,e g the amount of adsorption of xanthate doubled,the adsorption rate constant increased from 0 56 to 10 16, which showed the promoting effects of ammonium sulphate on xanthate adsored on the surface of minerals
