摘要：

The flotation of chalcopyrite particles was investigated using a modified Hallimond tube cell, in which the potential at the mineral-solution interface was controlled potentiostatically. Previous reports that this mineral displays natural flotability at oxidizing potentials and non-flotability at reducing potentials have been confirmed. Anodic oxidation of the mineral surface is responsible for the change from a hydrophilic to a hydrophobic condition. Linear potential sweep voltammetry has identified the products of the anodic reaction as CuS, Fe(OH)3 and S. The presence of sulphur on the mineral surface is considered to be the critical factor in rendering chalcopyrite flotable. © 1979.
