Experimental Study on Comprehensive Recovery of Copper and Sulfur in an Iron-copper Ore from Qinghai
摘要
Abstract
A refractory iron-copper ore in Qinghai Province, with characteristics of complex min-eral composition and complex dissemination, has a higher content of mafic silicate minerals, such as serpentine, olivine, and chlorite.According to easily slimezation characteristics of mafic silicate minerals, middlings on the first stage were separated further,greatly reducing the circulating load of middlings, weakening circulative accumulation of mud minerals and improving the separation in-dex.Comprehensive recovery of copper and sulfur was carried out using a "bulk flotation, copper-sulphur separation" process.A Copper concentrate with a Cu grade of 16.39%and a sulfur con-centrate with an S grade of 31.70%were obtained from the closed circuit test, in which the Cu re-covery was 73.04%and the sulfur recovery was 58.32%respectively.关键词
