Pomortseva O. Technology of recovery of platinum group metals from industrial wastes

Industrial wastes containing platinum, their composition. The creation of the flexible technological scheme which gives the opportunity to carry on the extraction of platinum metals from various raw materials. The complex of techniques of physico-chemical analysis and the ways of planning the experiments. The limiting stage of the whole process and the mechanism of platinoids solubility are determined. Precipitation stage with metallic aluminium is suggested. The possibility of the division of the process for separate stages is proved. The principle flexible technological scheme is proposed on this base. The research and industrial trials are accomplished. The field of application - enterprises of chemical industry.
