A concentrate which was under production at Dalseong mine, contains mainly cosalite (2PbS Bi₂S₃) bismuthinite (Bi₂S₃) and other minerals. This was roasted both in the tube furnace and reverberatory furnace. Pb in the roasted ore was then extracted with a hot aqeous solution of CaCl₂from which Pb was cooled to produce the white crystals of PbCl₂. The residue containing Bi, Au and Ag was smelted to produce crude bismuth in the crucible furnace. In the separation process, the recovery of Bi, Au, Ag was approximately 97% and the ratio of extraction of Pb in the ore was about 75%.
