Abstract

FIELD: metallurgy.
SUBSTANCE: method involves processing of base material during heating in water vapour atmosphere and further leaching of precious metals from processing product in solutions of reagents. Besides, processing of base material is performed in water vapour atmosphere, which is mixed with oxygen at the temperature of 300-500°C at oxygen content in gas mixture within 10-20%. Waste gases released during the processing are brought into contact with the solution that is combined with a leaching solution.
EFFECT: decrease of temperature and reduction of costs at preparation of refractory ores and concentrates to leaching.
