The company's main business: silver electrolysis unit, gold electrolysis unit, nitrogen oxide waste gas treatment system equipment, platinum, palladium and rhodium refining and purification production and other common equipment

A method for extracting lead and silver from zinc oxide leaching residue by wet process. The method includes: using NaCl-CaCl2 solution as the leaching agent, leaching the zinc oxide leaching residue with chloride salt to achieve the separation of silver, lead, sulfur and sulfate radicals. ; Use zinc flakes as the reducing agent and replace the primary leaching solution with zinc flakes, which solves the problem of zinc wrapping with lead sponge, and can obtain lead sponge containing lead ≥85% and silver content ≥450g/t.

It has changed the traditional process of sending zinc oxide leaching slag as an auxiliary material to the pyrotechnic lead smelting system to recover lead, silver and other valuable metals. It has solved the technical problem that zinc oxide leaching slag is difficult to be processed directly by wet process, and has a high metal recovery rate. , low production cost, low labor intensity, good operating conditions, no environmental pollution and other advantages.
