摘要
高岭土中的铁杂质严重影响高岭土产品品质,杂质中铁一般以磁铁矿、赤铁矿等弱磁性矿石为主.常规磁选机产生的场强不足,很难将高岭土中的弱磁性铁杂质分离出来.当采用磁场强度非常高的超导磁选机,能很好去除矿石中的各种弱磁性铁杂质,进而提高高岭土产品品质,提高企业的技术经济效益.试验研究表明,超导磁选高岭土中铁含量从1.04%降至0.53%,煅烧白度提高到85.6,可达到搪瓷工业TT-0级标准.
Iron impurities in kaolin seriously affect the quality of kaolin products, which are generally in form of weak magnetic ore, such as magnetite, hematite. The magnetic field intensity produced by conventional magnetic separators is insufficient, and it is difficult to separate the weak magnetic iron impurities from kaolin. When the magnetic intensity is very high, it can remove all kinds of weak magnetic iron impurities, and then improves the quality of kaolin products and the technical and economic benefits of enterprises. Experimental study shows that the iron content in the superconducting magnetic separation kaolin decreases from 1.04 % to 0.53 %, the calcination whiteness increases to 85.6, which meets the enamel industrial grade TT-0 standard.
