Abstract: Using chemical analysis, X-ray diffraction analysis, large polarizing microscope identification and other analysis and detection methods,A systematic process mineralogy study of a copper mine in Myanmar, The chemical composition and mineral group of the ore were found out,The structural structure, imbedding relationship and occurrence state of ore, According to the sulfide of copper in ore、The copper oxide is related to the content of secondary minerals in the oxidation zone of the copper deposit. The ore should be copper oxideStone to provide basic data and theoretical basis for beneficiation process.
