硫化锌精矿中铟的赋存及提取工艺概况

铟是我国的一种优势稀散金属,常与硫化锌多金属矿伴生,经过选矿后,铟主要富集于硫化锌精矿中.硫化锌精矿是提铟的最大原料来源,从硫化锌精矿中提取铟的研究一直是国内外冶金工作者关注的焦点之一.介绍了铟在硫化锌精矿中赋存的特点,结合铟在处理硫化锌精矿时的走向与行为规律,阐述了当前工业生产实践中所采用的铟的提取工艺和最新的研究动向,并指出了铟的传统提取工艺存在的弊端以及改进现有生产工艺或研究开发新的高效、清洁的提铟工艺的紧迫性与必要性.

A Review on the Occurrence Characteristics of Indium in Zinc Sulfide Concentrates and its Extraction Techniques

Indium is one of Chinag preponderant scattered metals. It is often associated with polymetallic zinc sulphide ores and mainly enriched into zinc sulfide concentrates after beneficiation. Thus, zinc sulfide concentrates become the main charge resources of indium. Study on extracting indium from zinc sulfide concentrates has attracted much attention home and abroad. The occurrence characteristics of indium in zinc sulfide concentrates is introduced, the behaviors of indium during the metallurgical processes of zinc sulfide concentrates disposal as well as the industrial practices and the latest research trends of indium extraction techniques are narrated. In addition, the defects of traditional indium extraction techniques together with the urgency and need for improving the existing techniques or developing new highly efficient and clean techniques are pointed out.
