For galena mineral, after grinding in porcelain jar using porcelain ball and iron ball, the effects of grinding time, slimy pH and collector dosage on galena flotation recovery were investigated. The results show that the ceramic grinding medium is more conducive to galena flotation than iron grinding medium; high alkali environment is conducive to galena flotation; collector dosage is higher for flotation of galena: using iron medium grinding, grinding time, galena flotation recovery rate decreased, and grinding with ceramic media. With the ceramic grinding medium, grinding time has little influence oil galena flotation recovery; the iron, iron oxidation of ferric hydroxide medium covered on galena surface, change the galena surface, galena increased hydrophilicity, have a negative impact on the flotation of galena. ? 2019 Editorial Department of Multipurpose Utilization of Mineral Resources.
