【摘要】 以察尔汗盐湖产出的低品位钾光卤石为原料,测试了钾光卤石的化学组成和物相组成,采用GFR705浮选药剂,研究了浮选介质、矿浆质量分数、药剂加入量、浮选时间等工艺条件对脱除石膏杂质的影响,结果表明反浮选工艺可以将低品位钾光卤石中的石膏脱除85%以上,脱钙后光卤石中的K+品位提高了30.84%,以脱钙光卤石为原料可以制取纯度95%的氯化钾产品,该工艺具有较好的工业应用前景。更多还原

【Abstract】 The structure and composition of the low grade carnallite mineral harvested in Chaerhan Salt Lake was tested and impacts of flotation medium,slurry content,reagent adding amount,flotation time and other process conditions on gypsum impurities using GFR705 flotation reagent.The results showed that 85% gypsum in low grade carnallite could be removed and grade in decalcified carnallite could increase by 30.84% and a purity of 95% potash could be produced from decalcified carnallite as raw material using reverse flotation process.The flotation process has a broad prospect in industrial application.更多还原
