A method for co-leaching high-silicon zinc roasted ore with high-sulfur zinc oxide powder

ActiveCN116732337Bavoid enteringIncrease initial ferric iron contentProcess efficiency improvementSULFUR/ZINC OXIDESlag
This invention relates to a method for the combined leaching of high-silicon zinc roasted ore and high-sulfur zinc oxide powder, belonging to the field of hydrometallurgical technology. The high-sulfur zinc oxide powder is leached neutrally to obtain zinc oxide leaching residue and zinc powder leaching solution. The zinc powder leaching solution is then mixed with high-silicon zinc roasted ore slurry for controlled silica leaching of the high-silicon zinc roasted ore to obtain zinc ore leaching residue and zinc ore leaching solution. The zinc powder leaching residue and zinc ore leaching residue are mixed and then subjected to low-acid leaching to obtain low-leaching residue and low-leaching solution. The low-leaching residue is then subjected to hot acid leaching to obtain hot-leaching residue and hot-leaching solution. The hot-acid residue is then subjected to high-acid leaching to obtain lead-silver slag product and high-leaching solution. The hot-leaching solution is neutralized and reduced by high-sulfur zinc oxide powder to obtain neutralized solution and neutralized residue. The neutralized solution is then subjected to mineralization and iron precipitation to obtain hematite product and iron-removed solution. This invention can effectively control the leaching of silicon in the high-silicon zinc roasted ore leaching process, and simultaneously realize the oxidative leaching of sulfides in zinc oxide powder and the reductive leaching of zinc ferrite in zinc roasted ore, thus simplifying the leaching process of zinc roasted ore and zinc oxide powder.
