evaluation of processing options for the treatment of zinc sulphide .the operation can be extended by processing of zinc sulphide concentrates. Leach kinetics of zinc sulphides are substantially slower than oxides, preventing the processing of zinc sulphides in the existing process under current conditions, and Skorpion Zinc faces the challenge to identify a suitable zinc sulphide treatment.skorpion leaching process and its conditions,leaching of secondary zinc oxides using sulphuric acidOptimum processing conditions for these materials were also briefly investigated. Leaching test work showed that it would be possible to obtain recoveries in excess of 93% on the EAF dust, 96.9% from the zinc dross and 98% from the flue dust samples in the Skorpion process, using the normal process conditions of 50°C,.
