J. Cent. South Univ. (2012) 19: 71-76 DOI: 10.1007/s11771-012-0974-9 Oxygen pressure acid leaching of Gacun complex Cu concentrates XU Bin(徐斌)1, 2, ZHONG Hong(钟宏)3, JIANG Tao(姜涛)1 1. School... with high contents of Pb, Zn, Ag, etc by oxygen pressure acid leaching was studied. It is unusual that tetrahedrite, whose treatment was rarely studied, is the primary copper mineral of the concentrates......
VACUUM-THERMAL ARSENIC EXTRACTION FROM GOLD-CONTAINING SULPHIDE CONCENTRATESIsakova R.A.,Chelokhsaev L.S.,Khrapunov B.E.,Spivak M.M.,Fedulov I.O.摘 要:<正> Arsenic is often occured in sulphide gold-containing ores and concentrates. The principal minerals of these materials are arsenopyrite (FeAsS), auripigment (As2S3), realgar(As2S2) and lollingite......
