巴西帕尔梅鲁波里斯矿冶金研究中心对矿区开采的重有色金属铜、铅、锌硫化矿的浮选进行了研究。研究选用的浮选剂为：戊基黄原酸钾（捕收剂），松木油（发泡剂），硫化铜（混合活化剂），硅酸钠（硅抑制剂），氢氧化钠（用来调整PH值）。当浮选液的PH值为10，浮选液按吨矿加人 The Palmeropolis Mining and Metallurgy Research Center in Brazil studied the flotation of heavy non-ferrous copper, lead and zinc sulphide ore mined in mining areas. The choice of flotation reagents for research: pentyl potassium xanthate (collector), pine oil (blowing agent), copper sulfide (mixed activator), sodium silicate (silicon inhibitor), sodium hydroxide To adjust the PH value). When the PH value of the flotation fluid is 10, the flotation fluid added by tons of ore
