METHOD FOR EXTRACTING OF NOBLE METALS FROM NOBLE METAL-CONTAINING MATERIAL Russian patent published in 2004 - IPC

Abstract RU 2224033 C1

FIELD: extraction of noble metals from sludge, used catalysts, ore etc. SUBSTANCE: method involves treating basic material with reactant solution while exposing to microwave field and transferring metals in solution. Treatment of basic material is performed with the use of acid and/or oxidizer used as reactant for producing of suspension from basic material and reactant solution. Power generated in unit of volume of suspension is maintained in the range of 100-10,000 kW/cu.m. Radiation is provided until suspension reaches boiling temperature. EFFECT: increased extent of noble metal extraction owing to availability of known range of required power. 3 cl, 13 ex
