Abstract
FIELD: extraction of noble metals. SUBSTANCE: cinder melting of gravitational concentrate roasting is %: SiO26-33; NaO 27-32; FeO27-32; FeO 3-4, and AlO- the rest at the following ratio of components, wt.-%: cinder 29-32; soda 46-60; quartz 11-22. Reducing agent is above 100% of charge mass 1.0-1.6, and reducing agent consumption is maintained at the level 50-80% of stoichiometry of reduction reaction of FeOto FeO with solid carbon. Method involving the use of collectorless melting of gold-arsenic concentrate and scarification of basic hematite part containing in cinder of gravitational concentrate, decreased reducing agent consumption (up to 50-80% of stoichiometry) ensures to exclude litharge consumption and increase noble metals part in the gold-silver alloy. EFFECT: enhanced degree of noble metals concentration in alloy. 4 tbl
