摘　　要：通过系统分析冶金烧结机头除尘灰的成分、物化性质等，结合磁选-浮选-重选选铁工艺，研究制定了浮选-重选循环水提取氯化钾的工艺流程，提取的氯化钾纯度达到93％以上，回收率达到80％左右，处理5万t烧结除尘灰，可以提取6000t左右的氯化钾。A technological process for extracting potassium chloride by flotation-reclassifying circulating water was investigated and worked out, via systematically analyzing the components and physico-chemical properties of dust collected from metallurgical sintering machine feed end, in the light of magnetic dress- ing-flotation-reclassifying iron dressing technique, with the rate of purity of extracted potassium chloride reaching above 93%, the rate of recovery being around 80%. Potassium chloride, more or less 6,000t can be extracted from 50,000-t sintering dust collected.
