对硫酸锌生产中新问题的探讨

Discussion on the New Problems in Production of Zinc Sulfate

针对硫酸锌生产中出现的压滤困难、锌粉用量大、双氧水用量大及排放严重超标、回收率大大降低等问题,进行了一些有建设性地探讨,指出其根源很可能是氧化锌产品中人为地加入了硫化锌矿石粉。

To solve the problems in production of zinc sulfate, which including pressure filtration difficulties, too large amount of zinc, too large amount of hydrogen peroxide, emission seriously exceeding the standard and greatly reduced percent recovery, etc., made some constructive discussion, point out that the cause of the problems likely is zinc sulfide ore powder artificially being added into the zinc oxide product.
