The processing of platinum bearing Ni-Cu ores for the extraction of platinum group metals (PGMs) involves comminution, flotation, smelting, and converter treatment of the furnace matte. Leaching circuits are predominantly used for further processing to separate the base metals and PGMs contained in the converter matte. Nickel dissolution is primarily achieved in the first stage leach (high pressure or atmospheric leaching, or a combination of the two), which is followed by second stage high pressure sulphuric acid/oxygen leaching to dissolve copper and the remaining nickel. PGMs are recovered from the leaching residue in downstream processes, and their dissolution in the first two leaching stages must hence be limited. Studies have been conducted to investigate the leaching mechanisms and kinetics of base metals in different leaching environments.
