| Abstract: | An experimental study has been made of the system Pb-Sn-Sb-S and of its sections Pb-Sn-S and PbS-Sb2S3 In aqueous solutions of HCl, NH4Cl and NaOH at T = 300–400°C and total pressure = PH2O= 1000 atm. All lead and antimony sulfosalts known in nature have been synthesized and also the following sulfostannates: teal lite, franckeite, and cylindrite. The phase relations In a part of the system Pb-Sn-Sb-3 are discussed and an attempt is made to use the experimental data for interpretation of the conditions of deposition of “Bolivian” type ores containing sulfosalts and sulfostannates. —Authors. |
