Abstract

Abstract

Experiments on the extraction of sulphur from the sulphides and oxysulphides such as MgS, CaS, BaS, RE₂S₃ and RE₂O₂S by hydrogen reduction have been carried out at 600~900℃ by means of hydrogen reduction-polarogra-phic analysis method. The reduction degree of various sulphides by H₂ at 800℃ is in the order of decreasing as follows:FeS>MgS ≥ RE₂S₃>RE₂O₂S ≥ CaS=BaS.
