摘要
以河南某钾长石为原料,采用重选结合磁选的方法进行除杂工艺研究,并利用提纯机针对细粒级含铁物料除杂,有效去除了长石矿物中的Fe_2O_3、TiO_2等有害杂质,最终精矿Fe_2O_3含量降到了0.106%,白度提高到了61.30%;并且通过该除杂工艺,将原矿中的Ta_2O_5和Nb_2O_5两种杂质去除并富集。不仅从根本上解决了杂质含量复杂的长石矿物除杂问题,为低品质钾长石的开发利用奠定良好的基础,还为微量有色元素的富集提供了新思路。
Use raw potassium feldspar from He＇nan province, through a combined technology of gravity separation and high intensity magnetic separation to study the method of purification, effectively removed the detrimental impurities like Fe_2O_3 and TiO_2 in raw feldspar. The content of Fe_2O_3 is reduced to 0.106% in the concentration, and its whiteness increased to 61.30%, Ta_2O_5 and Nb_2O_5 in raw material are concentrated and removed through this purifying technology. Not only solved the purification of multiple impurities in feldspar, this paper also sets foundation for the usage of low quality potassium feldspar and provides a new thought for the enrichment of nonferrous elements.
