Abstract

The constitution of the ternary mattes CU₂S-FeS-PbS has never been completely investigated. Fulton and Goodner 1) have investigated the binary mattes CU₂S-FeS, CU₂S-PbS, PbSFeS and have shown that the three binaries show eutectics. There has been no attempt however to draw the complete ternary diagram. The following work is intended to be a contribution toward the completion of this diagram by first of all pointing out those mattes which separate on melting into two layers, and second by determining the specific gravities of mattes of different compositions.
