无捕收剂浮选的研究已延续了几十年,70年代以来,国外无捕收剂浮选的研究取得了进展,已有成功的应用于生产,提高了铜精矿品位和次生硫化铜的作业回收率,降低了伴生金属的损失。近两年来,国内黄开国,王淀佐等人对硫化铜矿(包括斑岩铜矿、矽卡岩铜矿和浸染型铜矿)无捕收剂浮选取得了与加捕收剂浮选相同指标。并在另一篇报导中列举获得的试验数据,准备进行工业试验。
Research on collectorless flotation has been carried out for several decades. Since the 1970s, there has been some progress in research on collectorless flotation abroad, which has been successfully applied to the production and improved the grade of copper concentrate and the secondary vulcanization Recovery of copper operations, reducing the associated metal loss. In the past two years, Huang Kai-guo and Wang Dian-zuo, both from China, have obtained the same indexes of collector flotation for copper sulfide ores (including porphyry copper ores, skarn copper ores and disseminated copper ores) . In a separate article cited in the experimental data obtained, ready for industrial tests.
