波兰硫化铅锌矿(含有一定量的氧化矿)是用重选和选择性浮选来处理的,从重选回路中产出的尾矿被用作混凝土的石料,迄今为此,浮选尾矿还未利用,系统的调查研究发现:方铅矿过磨而与此同时闪锌矿欠磨。由于矿物不同的特性,使之具有相反的指标。已发现采用下列措施可以改进选别指标:放粗浮选给矿磨矿粒度(方铅矿不过磨)、锌浮选尾矿进行分级、对粗粒部分再磨,对磨后矿物进行铅和锌的扫选、扫选精矿返回原流程。这样可降低铅和锌的损失,扫选尾矿有望作为钙镁肥料出售。
Polish lead sulphide ore (containing a certain amount of oxide ore) is treated with re-election and selective flotation. The tailings produced from the re-election circuit are used as concrete stones. To date, flotation tailings Not yet used, the systematic investigation found that: Galena over grinding at the same time sphalerite under wear. Due to the different characteristics of minerals, it has the opposite index. It has been found that the following measures can be used to improve the sorting index: coarse grading flotation ore size (grit but not mill), zinc flotation tailings grading, regrinding of the coarse fraction, grinding of minerals after lead and Zinc sweep, sweep the concentrate returned to the original process. This will reduce the loss of lead and zinc, scavenging tailings is expected to be sold as calcium and magnesium fertilizer.
