Experimental formation of Pb, Sn, Ge and Sb sulfides, selenides and chlorides in the presence of sal ammoniac: A contribution to the understanding of the mineral formation processes in coal wastes self-ignition

International Journal of Coal Geology, 2017
Abstract The formation of sulfides, selenides and chlorides was experimentally studied at 800 or 900 °C in the presence of sal ammoniac in sealed silica glass tubes. Synthetic PbS, PbSe, SnS, GeS, SnGeS2, PbSnS3, SnS, Sb2S3, and natural uraninite were used as substrates.
