本报告叙述了萤石和方解石的分选作用的试验结果。试验以纯矿物在小型浮选机中进行。首先研究了油酸对纯营石、纯方解石、以及纯萤石和纯方解石混合物的作用,然后研究了克勃拉哥对上述物料的作用,特别注意了温度的影响。为了验证纯矿物的研究结果,又曾以各种不同类型的萤石矿石进行了可选性的试验,结果证明用克勃拉哥及矿浆加温的办法可大大提高萤石品位及采收率,并且发现了在浮选前可以用加药干磨及热处理的办法而得到比普通的泾法磨矿还要好的浮选结果。
This report describes the test results of the sorting of fluorite and calcite. The experiment was conducted with pure mineral in a small flotation machine. Firstly, the effect of oleic acid on pure campanite, pure calcite and the mixture of pure fluorite and pure calcite was studied. Then, the effect of Clorogol on the above materials was studied, with special attention paid to the influence of temperature. In order to verify the results of pure minerals, but also with a variety of different types of fluorite ore carried out optional tests, the results show that with Kobarago and pulp heating method can greatly improve the fluorite grade and recovery , And found that before the flotation can be used dry powder processing and heat treatment approach to get even better than the ordinary Jing law flotation results.
