非金属矿物原料在国民经济建设中、在现代技术中的需要量越来越大。为此需要加快矿产质量的评价及工艺流程试验步伐。而衡量非金属矿的质量、工艺流程的效果主要决定干非金属矿的含量,甚至是需要大量的单矿物或是纯度很高的矿物,以满足现代技术发展中的一些特殊要求。重液变温法可以高质量地短时间地完成分选和提纯任务。 Non-metallic mineral raw materials in the national economy, the growing demand in modern technology. To do this, we need to speed up the evaluation of mineral quality and the pace of process testing. The measure of the quality of non-metallic minerals, the effect of the process determines the main non-metallic mineral content, and even need a large number of single minerals or minerals of high purity to meet the special requirements of the development of modern technology. Heavy liquid temperature method can be high quality short time to complete the sorting and purification tasks.
