Synthetic PbS, PbSe, SnS, GeS, SnGeS2, PbSnS3, SnS, Sb2S3, and natural uraninite were used as substrates. Depending on the chemical composition of the sulfide/selenide charge, compounds corresponding to cotunnite, galena, herzenbergite, berndtite, ottemannite, stibnite, panichiite, and unnamed SnGeS3, SnSb2S4 and Sn2Sb3S6 phases were identified in sublimates. Results of the experiments revealed that an addition of chlorine may contribute to the mobility of metals and metalloids in coal wastes self-burning processes.
