我国昆阳群地层内常有铈铀钛铁矿产出。其产状有三种:第一种产于角闪斜长片麻岩高温热液铀矿化中,与晶质铀矿伴生;第二种产于古火山岩型铜铁矿床贫铁矿石内,伴生有磁铁矿、黄铁矿及黄铜矿;第三种产于煌斑岩及变质岩内,常呈粗晶产出。上述各铈铀钛铁矿的化学成分及物理性质都有所不同,并且具有不同程度的电磁性。我们采取以电磁选为主,其他分离为辅的方法,对铈铀钛铁矿进行了提纯。纯度可达97—98％。
The Kunyang Formation strata in our country often contain cerium and uranium ilmenite. There are three kinds of its occurrence: the first produced in the hornblende plagiogranite high temperature hydrothermal uranium mineralization associated with the crystalline uranium; the second produced in the ancient volcanic rock-type iron-copper ore-poor iron ore , Associated with magnetite, pyrite and chalcopyrite; the third species in lamprophyre and metamorphic rocks, often coarse grain output. The cerium uranium ilmenite chemical composition and physical properties are different, and have varying degrees of electromagnetic. We take to electromagnetic separation-based, other separation supplemented by the method of cerium uranium ilmenite was purified. Purity up to 97-98%.
