Abstract
The occurrence states of copper and iron in smelting copper slag are explained,the effect factors of copper and iron recovery from smelting copper slag are analyzed.Experiment was made on a technological process of flotation and magnetic separation to comprehensively recover copper and iron in the smelting slag from a copper company,and good separation indexes were achieved.By a closed circuit consisting of one roughing,two scavenging and re-concentration,at the grinding fineness of-0.037 mm fractions taking up 95.27%,a copper concentrate grading 46.36% at a recovery 83.63% was obtained.An iron concentrate grading 51.81% at a recovery of 30.88% was obtained by means of regrinding and adding dispersant.
