摘要
通过光学显微镜、X射线衍射、X射线荧光光谱、EDS能谱以及化学分析,对辽宁省大石桥市某菱镁矿选矿厂浮选精矿进行了工艺矿物学研究。结果表明,该菱镁矿主要杂质矿物为磷灰石、石英等,钙杂质主要赋存在含钙菱镁矿和磷灰石中,铁杂质主要赋存在菱镁矿晶格中。
The process mineralogy of flotation concentrates in a magnesite concentrator in Dashiqiao,Liaoning Province was studied by optical microscopy, X-ray fluorescence spectroscopy, X-ray diffraction,energy spectrum and chemical analyses. The results showed that the main impurities of the magnesite were apatite, dolomite, quartz, etc. Calcium was found in Ca-bearing magnesite and apatite. In addition, a significant portion of iron may be present in the magnesite crystal lattice.
