БЛАГОРОДНЫЕ МЕТАЛЛЫ В СОЛЯХ ВЕРХНЕКАМСКОГО МЕСТОРОЖДЕНИЯ

Abstract

There was carried out, during the last decade, considerable volume of investigations studying contents, distribution and forms of occurrence of gold, silver and PGM in salts of Verkhnekamskoye potassium salt deposit. Contents of the precious metals were determined within insoluble residue of salt samples from productive layers and its remnants after chloroform and alcohol-benzene extracts. Thus, it has been revealed that the basic forms of Au, Pt and Pd occurrence are connected with various organic compounds. It was detected also that after separation of insoluble residue from the salt matrix, with time, the transformation of structure and composition of the residue took place, and it is represented in blocking of organic compounds of those precious metals.
