新疆可可托海矿是一个富含锂、铍、钽铌的多稀有金属伟晶岩矿床。主要金属矿物为锂辉石、绿柱石和钽铌铁矿等,脉石矿物主要是长石、石英、白云母、以及少量的角闪石、电气石、黑云母等。各种矿物的含量因矿带而异。就含锂矿石而言,选矿厂用重选法和浮选法分别回收了钽铌铁矿精矿和锂辉石精矿。其尾矿是比较纯的长石、石英和白云母混合精矿,其中长石、石英和白云母约占98％以上,还有少量锂辉石、电气石和角闪石等。这部分资源未被利用。为了逐步利用选矿厂尾矿,我们曾对锂辉石浮选尾矿
Xinjiang coco Tuohai mine is a multi-rare metal pegmatite deposit rich in lithium, beryllium, tantalum and niobium. The main metal minerals are spodumene, beryl and tantalum-niobium iron ore, gangue minerals are mainly feldspar, quartz, muscovite, and a small amount of amphibole, tourmaline, biotite and so on. The content of various minerals varies with the orebelt. For lithium-bearing ores, beneficiation plants recover tantalum-niobium iron ore concentrates and spodumene concentrates by gravity and flotation respectively. The tailings are relatively pure feldspar, quartz and muscovite mixed concentrate, of which feldspar, quartz and muscovite accounts for about 98%, as well as a small amount of spodumene, tourmaline and amphibole. This part of the resources is not used. In order to gradually use the tailings of the concentrator, we have flotation tailings for spodumene
