Abstract
The distribution of chalcogens and noble metals during the processing of roasting dust from JSC Kola MMC is studied and it is found that these elements are present in all products of the process. Methods are proposed to obtain selenium–tellurium- and silver-containing concentrates, and also a concentrate of noble metals. Conditions are determined for the integrated processing of the dust and selenium dump waste product to obtain products that comply with the process operating procedure.
