前言某难选锡中矿高温氯化挥发工艺,采用湿法收尘回收多种有价金属。收尘沉淀主要含锡、铅,其余金属如砷、锌、铟、铋、镉等均进入收尘溶液中。为了分离提取上述金属,近年来作了大量的研究工作。用铁盐法从收尘溶液中沉淀出的砷化 Foreword An intractable tin mine high temperature chlorinated volatile technology, the use of wet dust recovery of a variety of valuable metals. Dust precipitation mainly contains tin, lead, other metals such as arsenic, zinc, indium, bismuth, cadmium, etc. into the dust collection solution. In order to separate and extract the above metals, a great deal of research work has been done in recent years. Iron arsenide precipitated from dusting solution by iron salt method
