Process for reducing consumption of hydrochloric acid during chlorination distillation of germanium-containing raw material

一种降低含锗原料氯化蒸馏时盐酸消耗的工艺方法

Abstract

本发明涉及湿法冶金技术领域,具体地说是一种采用氯化镁-盐酸蒸馏法来回收含锗原料中锗的方法。本发明公开了一种降低含锗原料氯化蒸馏时盐酸消耗的工艺方法,其特征在于对含锗原料进行预处理后,用氯化镁代替部分工业盐酸与含锗原料反应,并循环利用部分蒸馏残液进行蒸馏,采用了上述两种措施后即可以大大降低各种锗原料在氯化蒸馏时盐酸的消耗量和中和废液的生石灰的消耗量,又不影响锗的回收,从而达到降低生产成本的目的。
The invention relates to the technical field of hydrometallurgy, in particular to a method for recycling germanium from a germanium-containing raw material through the magnesium chloride-hydrochloric acid distillation method. The invention discloses a process for reducing the consumption of hydrochloric acid during the chlorination distillation of the germanium-containing raw material. The process is characterized in that after the germanium-containing raw material is pretreated, magnesium chloride is used to replace a part of industrial hydrochloric acid to react with the germanium-containing raw material, and a part of distillation residual liquid is recycled to distill. By adopting the two measures, the consumption of hydrochloric acid during the chlorination distillation of each germanium raw material can be greatly reduced and the consumption of quick lime for neutralizing the waste liquid can be greatly reduced. Therefore, the aim of reducing the production cost can be achieved.
