天然的非金属矿石往往含有不同成分的杂质,影响了产品的利用和纯度。非金属矿的提纯,是满足工业部门需要的一个重要环节。下面就有关非金属矿的提供技术列例介绍如下。1 非金属矿的提纯1.1 粘土矿物的提纯 粘土原矿中常含有绢云母、高岭石、腊石等粘土矿物,另外,还往往含有硫化铁、闪锌矿、硫化钼等硫化矿物。除去这些硫化物精制粘土矿物的方法很多,如多油式、泡沫式等浮选法,还有
Natural non-metallic ores often contain impurities of different composition, affecting the product utilization and purity. The purification of non-metallic minerals is an important part of meeting the needs of the industrial sector. The following is a list of technologies for providing non-metallic ores. A non-metallic mineral purification 1.1 clay mineral purification Clay ore often contain sericite, kaolinite, wax stone and other clay minerals, in addition, often contain iron sulfide, sphalerite, molybdenum sulfide and other sulfide minerals. There are many ways to remove these sulfide refined clay minerals, such as multi-oil type, foam type flotation method, and
