    摘要: A process for controlling the water balance and the concentration of impurities in an electrolytic zinc plant circuit with which is operated at least one selective zinc precipitation (SZP) process plant which comprises one or more of the steps(a) a two-stage SZP process plant in which a compound containing calcium carbonate is used in the first-stage to precipitate portion of the zinc in incoming solution, and a compound R containing zinc oxide, preferably calcined zinc sulphide concentrate, is used to precipitate most of the remaining zinc;(b) displacement of the zinc depleted solution associated with solids leaving the SZP process plant by solution drawn from the electrolytic zinc plant circuit, and(c) use of a compound R with a particular average particle size.
