摘要： The process comprises the following stages: a) leaching; b) solid-liquid separation; c) neutralization of the aqueous solution; d) solid-liquid separation of the zinc-rich solution; e) zinc extraction; f) purification of the organic solvent from the extraction stage; g) stripping the ionic zinc loaded in the organic solvent; h) recovering the zinc contained in the aqueous acid solution from the stripping. The following barriers to impurities have been established: gentle leaching; alkaline pulp treatment; treatment of a small stream of aqueous solution, collected before and/or after the zinc extraction at step e); high selectivity of the dissolved zinc extraction; treatment of the zinc loaded in the organic solvent; cleaning treatment of the zinc-laden organic solvent, with an ultra-pure acid solution; partial bleeding and treatment of the stripped organic solvent; bleed of small stream of the final product producing loop, which will be recycled to the organic loop.
