本文概述了催化氧化酶浸法处理硫化锌精矿的结果.采用催化氧化酸浸(100℃,400KPaA)-和氧化除铁-锌粉置换除铜镉-碳酸铵(或碳酸氢铵+氨水)沉淀碱式碳酸锌的全湿法新工艺可生产一级减式碳酸锌,催化氧化酸浸之锌浸出率为95%.所得产品经新技术──等离子热分解可获得超细活性氧化锌。也可将所得硫酸锌溶液净化后用于锌电积,获得符合标准要求的电积锌。
This article summarizes the results of catalytic oxidase digestion of zinc sulphide concentrate. A total wet process for the precipitation of basic zinc carbonate by copper-cadmium-ammonium carbonate (or ammonium bicarbonate + ammonia) by catalytic oxidation and acid leaching (100 ° C, 400 KPaA) and oxidation of iron- Zinc carbonate, zinc oxide acid leaching rate of 95%. The resulting product by the new technology ─ ─ plasma thermal decomposition of ultrafine active zinc oxide. The resulting zinc sulfate solution can also be purified for zinc electrowinning to obtain electrowinning zinc that meets the standard requirements.
