摘要:
西藏甲玛矿区铜铅锌氧化矿资源储量大，但矿石复杂难选。为查明矿石特性，综合利用镜下观察、X射线粉末衍射分析、人工重砂分析、电子探针分析、矿物解离度分析等手段，对该矿石进行了详细的工艺矿物学研究。结果表明：矿石由硫化物、氧化物和硅酸盐等8类34种矿物组成，其中硅酸盐为72.31 %、碳酸盐为16.71 %、氧化物为7.40 %；铜、铅、锌矿物共生关系复杂，方铅矿多与黄铜矿、闪锌矿连生或包裹于闪锌矿中；铜矿物、锌矿物嵌布粒度细，且锌矿物易随?笪锔患焕谕⑶Α⑿糠掷搿Ｑ芯拷峁每笫厥展ひ昭≡裉峁┛笪镅б谰荨

Abstract:
The copper-lead-zinc oxide ore reserve is in large scale in Jiama Mining District,Tibet,but the ores are complex and refractory.In order to investigate the ore property,microscopic observation,X-ray powder diffraction analysis,artificial heavy concentrate analysis,electronic probe analysis and mineral dissociation degree analysis are comprehensively used and thorough study on the process mineralogy is carried out.The results show that the ore is composed of 8 kind of minerals,totaling 34 minerals,including sulfide,oxide and silicate.Among them,silicate content is 72.31 %,carbonate content is 16.71 %,oxide content is 7.40 %;copper,lead and zinc are in complicated intergrowth relation,and galena usually associates with chalcopyrite and blende or is included in blende;copper and zinc minerals are disseminated in fine grains,and the zinc minerals are easily enriched with copper minerals,which is detrimental to the separation of copper,lead and zinc.The research results provide mineralogical basis for the selection of extraction methods of the ores.
