高含冰碛物铜钼矿的矿物学特征及富集工艺研究
Study on mineralogical characteristics and enrichment process of copper-molybdenum ore with high moraine content
摘要
Abstract
The resource potential of copper-molybdenum ore rich in moraine in high altitude area is huge,but its complex mineral composition and high mud content increase the difficulty of mineral processing.In this paper,Pulang Copper Mine is taken as the research object.By analyzing the mineralogical characteristics of the ore,the flotation process parameters and reagent system are optimized to achieve efficient enrichment of high-slim copper-molybdenum ore.The study of process mineralogy shows that the main metal minerals in the ore are chalcopyrite and molybdenite,and the gangue minerals are mainly quartz,plagioclase,K-feldspar,muscovite and biotite.The content of easily mudding minerals is high,which leads to serious mudding in the grinding process.Based on the analysis of process mineralogy,the effects of grinding fineness,pH,inhibitor and collector dosage on flotation effect were investigated by flotation test.The optimum process conditions are as follows:grinding fineness of-0.074 mm accounted for 65%,pH=8,CMC dosage of 300 g/t,combined collector(YK-9016+YK-111)dosage of 60 g/t,and HCCL dosage of 50 g/t.Under these conditions,the copper-molybdenum mixed concentrate obtained by closed-circuit flotation test has a copper grade of 22.15%,a copper recovery of 81.38%,a molybdenum grade of 1.060%,and a molybdenum reco-very of 70.10%.This study reveals the relationship between the mineralogical characteristics and flotation behavior of copper-molybdenum ore with high moraine content,and proposes a targeted process optimization scheme,which can provide reference for the development and utilization of similar resources in high altitude areas.关键词
