目前,应用WCF_2型多用磁性分析仪,分选和提纯单矿物时,一般采用常规的“理想可选电流值”,直接提纯目的矿物。我们在长崴子硅灰石矿区花岗岩体同位素年龄提纯角闪石、黑云母时,觉得常规提纯法不甚完善。经反复实验证明,使用该型仪器提纯角闪石、黑云母矿物,首先用大电流,把角闪石吸咐在磁极上,先清除非目的矿物,然后再调解电流,使角闪石离开磁极,将电流从大到小变化,反复分选,达到提纯
At present, the use of WCF_2 multi-purpose magnetic analyzer, sorting and purification of single mineral, the general use of the conventional “ideal current value,” the direct purification of minerals. We are in Chang Wei sub-wollastonite granitic granite isotopic age purification hornblende, biotite, that the conventional purification method is not perfect. After repeated experiments show that the use of this type of instrument purifying amphibole, biotite mineral, first with a large current, the amphibole to be adsorbed on the pole, the first removal of non-target minerals, and then mediate the current, the amphibole to leave the pole , The current changes from big to small, repeated sorting, to purification
