METHOD TO EXTRACT SILVER FROM SOLUTIONS WITH HEAVY METALS CATIONS Russian patent published in 1995 - IPC

Abstract RU 2044077 C1

FIELD: geological microbiology. SUBSTANCE: wastes of antibiotics production and yeast are introduced in solution that has heavy metals cations, in ratio of 1 g of biomass per 25-200 ml of solution under solution temperature of 4-50 C. Then desired product is extracted under pH 0.6-2.6 during 0.5 3 hours. EFFECT: increase efficiency of the method.
