METHOD OF EXTRACTING METALS FROM SECONDARY RAW MATERIALS AND OTHER MATERIALS WITH ORGANIC COMPONENTS Russian patent published in 2019 - IPC C22B7/00 C22B1/216 C22B15/06

Abstract RU 2689828 C2

FIELD: technological processes.

SUBSTANCE: invention relates to extraction of metals, for example, noble metals or copper, from secondary raw material and other materials with organic components. Secondary raw material is prepared by removing organic components therefrom. Extraction is carried out at least two-sidedly for extraction of at least one first metal and one second metal. After the first stage of the process gas is treated to reduce content of combustible gases and hazardous substances. Ratio of organic components of the secondary raw material ranges from 5 % to 60 %, and a high rate of conversion of substances is achieved.

EFFECT: method increases amount of processed material with reduced content of hazardous substances in off-gas.
