第一节锂矿床简述锂在地壳中的分布很广,其克拉克值为5×10~(-3),从上述含量看,锂并不稀有。目前,我们已知的锂矿物大约有150种左右,其中含量大于2％的有30多种,在这30多种锂矿物中,具有工业价值的主要有锂辉石、锂云母和盐湖卤水锂矿,其次是透锂长石、锂磷铝石、锂绿泥石、磷铁锂矿和磷锰矿等。另外在部分花岗伟晶岩矿床中,还有一种“腐锂辉石”的矿物,这种矿物与锂辉石的颜色、光泽、结晶形态等特征极为相似,但氧化锂含量极低,一般仅有0.1～1.5％。锂辉石和锂云母常赋存于钠锂型花岗伟晶岩矿
Section I Lithium Deposit Description Lithium is widely distributed in the crust, the Clarke value of 5 × 10 ~ (-3), from the above content, lithium is not rare. At present, there are about 150 kinds of lithium minerals known to us, of which more than 30 are contained in more than 2%. Among these 30 kinds of lithium minerals, there are mainly industrial value spodumene, lepidolite and salt lake brine lithium Ore, followed by lithium feldspar, lithium apatite, lithium chlorite, lithium iron phosphate and phosphorus manganese ore and so on. In addition, part of the granitic pegmatite deposits, there is a “tumbleite spodumene” minerals, spodumene this mineral and spinel color, luster, crystal morphology and other characteristics are very similar, but very low levels of lithium oxide, the general Only 0.1 ~ 1.5%. Spodumene and lithium mica are commonly found in sodium-type granite pegmatite ore
