Method and equipment for synergistically recovering valuable metals from lead-zinc smoke dust and urban mineral products

The invention provides a method and equipment for recovering valuable metals through synergistic reduction of lead-zinc smoke dust and urban mineral products. Comprising the following steps: preparing lead-zinc smoke dust, a zinc-lead oxide material and urban minerals into a block mass, mixing the block mass with a first reducing agent, and adding the mixture into smelting equipment to form a bed layer material; blowing a first oxygen-enriched gas into the bed material, and reducing to obtain a first zinc-containing gas, liquid lead metal and unreduced oxides and gangue; and then the first reducing agent, the second oxygen-enriched gas and the reaction flux drop into the bottom molten pool to form a to-be-reduced melt, a second reducing agent, the second oxygen-enriched gas and the reaction flux are blown into the to-be-reduced melt for reaction, reaction gas is obtained, and the first zinc-containing gas and the second zinc-containing gas are captured and recycled to obtain zinc metal. The method is easy to
