我国西北产于基性超基性岩中的铬矿大都或多或少伴生有铂族元素,有的达到了综合回收的要求。如藏北超基性岩带中某铬矿含铂族元素达0.908克/吨。搞清矿石中铂族元素能否综合回收利用,对综合评价矿床的工业价值,对资源的综合利用均具有一定的意义。为此,本文从矿石的工艺要求角度,介绍某铬矿中铂族元素的赋存状态。
Most of the chrome ore produced in the basic ultrabasic rocks in the northwestern China is mostly associated with platinum group elements, some of them meet the requirements of comprehensive recovery. For example, a chromite in the ultrabasic belt in northern Tibet contains 0.908g / t of platinum group elements. To find out whether the comprehensive recovery and utilization of platinum group elements in ore is of great significance to the comprehensive evaluation of the industrial value of the deposit and to the comprehensive utilization of resources. Therefore, this paper describes the occurrence of platinum group elements in a chromium ore from the perspective of technological requirements of ore.
