江西有色冶炼加工厂的锌冶炼,过去按传统的湿法工艺(焙烧——中浸——净化——电积)生产金属锌,有渣含锌高、渣率大、回收率低的缺点,这也是现有生产单位所共同存在的问题。为了提高湿法炼锌工艺的主要技术经济指标,改革现有工艺,目前国内外一致认为,采用高温高酸强化浸出黄钾铁矾沉铁新工艺是一个有效的途径,现已有几种不同的工艺方案。浙江省冶金研究
In the past, zinc smelting in nonferrous smelting processing plants in Jiangxi Province used to produce metallic zinc according to the traditional wet process (roasting - immersion - purifying - electrowinning) with the disadvantages of high zinc content, large slag rate and low recovery rate, This is also a common problem existing in the production units. In order to improve the main technical and economic indexes of wet-process zinc smelting process and reform existing technology, at home and abroad, at present, it is unanimously agreed that it is an effective way to leach the new process of jarosite by high temperature and high acid. There are several different ways The process plan. Zhejiang Metallurgy Research
