Study on Process Mineralogy of Comprehensive Tailings in Nanfen Concentrator
In order to realize the recovery and utilization of comprehensive tailings and provide refer-ence for reasonable selection of beneficiation process and parameters,the comprehensive tailings are taken as the research object,and the mineralogical characteristics of tailings are studied by MLA mineral automat-ic analysis system.The results show that the total iron grade of the comprehensive tailings is 9.64%,and the iron mainly exists in the form of hematite and limonite,with a distribution rate of 63.49%.Secondly,iron ex-ists in the form of magnetite with a distribution rate of 12.20%.The main gangue minerals are quartz,magne-sium iron amphibole,chlorite and tremolite,and the content of other minerals is low.The content of -75 μm of magnetite and hematite accounted for 85.71%,and the degree of monomer dissociation was 63.88%.Among them,a small amount of quartz is wrapped by the magnetic and hematite of the monomer,and the wrapped magnetic and hematite are mainly wrapped by minerals such as quartz.The rich coenobium con-tains more quartz and a small amount of siderite.
