方铅矿表面亲水性及浮选抑制机理研究进展OA

Galena is the important lead sulfide mineral with good floatability,often associated with other metal sul-fide ores with similar floatability,leading to flotation separation difficulties.The intrinsic principles of crystal struc-ture and lattice defects,semiconductor properties,surface oxidation,pulp pH,pulp potential and other factors affect-ing the hydrophilicity of galena are introduced,and the flotation inhibition mechanisms of inorganic inhibitors,organic inhibitors,combined inhibitors and other inhibitors are summarized.The development of non-toxic,environmentally friendly and efficient single selective inhibitors and combination inhibitors is the important research direction of galena flotation separation.
