摘要
针对中越边境某氧化镍矿石中同时存在有结晶程度差或非晶质矿物、结晶粒度细的矿物、化学组成多变的矿物,利用常规方法无法准确定量。文章提出利用选矿技术选别,将这些矿物分组后,通过镜下鉴定、化学多项分析、X射线衍射分析、电子探针微区分析等手段进行矿物定量。实践证明,这种方法的矿物定量结果准确,可操作性强。
Simultaneously exists in view of the Chinese and Vietnamese frontier some nickel oxide ore has the degree of crystallinity difference or the noncrystal mineral, the crystal granularity thin mineral, the chemical composition changeable mineral, There mineral composition in ore is unable the accurate quota using the conventional method. The article proposed the use dressing technology classification, after these mineral grouping, appraises, chemistry many analyses, X beam diffraction analysis, through the mirror under methods and so on electron probe micro area analysis carries on the mineral quota. The practice proved that, this method mineral quota result is accurate, feasibility.
