Title
The Effects of Ni , Co and Fe on the Gold and platinum Distribution between matte and Speiss in Cu - As - S System
박현순 H . S . Park
Abstract
Quaternary systems Cu-As-Ni (Co, Fe)-S with Au or Pt were studied at 1200℃ for Au and Pt distribution between matte and speiss. 1) Au or Pt exists almost in speiss. The content of Au or Pt in speiss is increased with the Cu content (except Cu content as Cu₂S) in speiss. 2) Pt distribution in the quatenary systems has similar trend to that of Au. The ratio of distribution coefficient of Au or Pt (K_(Au) or K_(Pt)), which is defined as the ratio of weight percentage of the noble metals in matte to that in speiss, can be expressed as follow: K_(Pt):K_(Au):K_(Ag)=1:10:50. 3) The effect of Ni on Au solubility in speiss is not same as that of Co or Fe, because Ni forms solid solution with Au in all composition range.
