自1904年兴起泡沫浮选,特别是1924年以来,发现黄原酸盐可以浮选有色金属硫化矿,浮选工艺取得很大进展,现已成为选矿技术中最重要的方法之一。随着浮选工业的发展,浮选药剂的消耗量也逐年增长,美国各浮选厂1975年各种药剂的消耗量达80万吨,价值8768万美元,其选矿药剂消耗情况与价值如表。由表可知耗量最大的为调整剂,其次是捕收剂,抑制剂为第三位。
Froth flotation began in 1904, and especially since 1924, it has been found that xanthogenate can flotate non-ferrous sulphide ore. The flotation process has made great progress and has become one of the most important methods in mineral processing. With the development of the flotation industry, the consumption of flotation reagents has also increased year by year. The flotation plants in the United States consumed 800,000 tons of all kinds of pharmaceutical products in 1975, worth USD 87.68 million. The consumption and value of their beneficiation reagents are as follows . From the table shows that the largest consumption of the regulator, followed by collectors, inhibitors for the third place.
