FIELD: metallurgy.
SUBSTANCE: invention relates to the development of a combined technology for the enrichment of oxidized lead-zinc ores based on sulfidizing roasting in an atmosphere of water vapor and can be used in the preparation of oxidized lead-zinc ores of various genesis for flotation. Processing of oxidized lead-zinc ores includes sulfidizing roasting of oxidized lead-zinc ores with a sulfidizer in a steam atmosphere. As a sulfidizer, lead-zinc sulfide ore, including refractory ore, from the same deposit is used.
EFFECT: method allows to increase the content of lead and zinc in the charge.
