Surfaces of metal sulfides react readily with selected constituents of environment. Two types of reaction products may form: (1) primary, chemisorbed and hydrophobic surface products or primary hydrophilic surface products, and (2) secondary reaction products -- produced during continued oxidation-reduction processes. For flotation, the chemisorbed surface product and the secondary reaction products, elemental sulfur or metal xanthates, must provide sufficient hydrophobicity of the surface to ensure particle-bubble attachment.
