【摘要】 本论文采用沉降率法、正浮选法。在p H相同的条件下,加入C8-C18系列直链脂肪酸纳捕收剂与碳酸钙分别进行沉降实验和浮选实验,结果表明沉降率越低,浮选指数K越大,捕收剂与矿浆中碳酸钙结合能力越强,浮选效果越好,这对于下一步的脂肪酸浮选药剂改性实验具有一定的指导意义。更多还原

【Abstract】 The forward flotation and the sedimentation rate methods were used in this article. The experiment was in the same p H value conditions. The results show that the lower the settlement rate is,the larger the flotation index becomes,and the firmer the binding ability which is shown between the collectors and calcium carbonate,the better flotation effect is. This will have the certain instructive significance for the next step of fatty acid flotation agent modified experiment.更多还原
