绪言新疆可可托海三号脉属伟晶花岗岩矿床,是我国生产锂辉石的主要矿山。矿石经过选矿后所得的锂辉石精矿主要用于生产锂盐。随着工业的发展,锂辉石的用途日益扩大。加之国内外市场对锂辉石品级的要求越来越严。为此我们根据锂精矿中Fe_2O_3的含量及其用途分为以下三级,见表1 Introduction Xinjiang Keke Tuohai No.3 vein is a pegmatite granite deposit, which is the main mine producing spodumene in China. After the ore beneficiation resulting spodumene concentrate is mainly used for the production of lithium salt. With the development of industry, the use of spodumene is expanding. Coupled with domestic and foreign markets on the requirements of spodumene more and more stringent. To this end we are divided into the following three levels according to the content of Fe 2 O 3 in lithium concentrate and its use, as shown in Table 1
