从锌浸出渣中浮选银基础条件研究

摘要

This paper researches the flotation characters of acidic leaching residues in conventional zinc leac-hing process in zinc hydrometallurgy , then it discusses and provides the main conditions for recovering sil-ver from conventional zinc leaching residues by flotation . It considers that this process has the obvious ad-vantage , w hich uses acidic conventional zinc leaching residues as the original pulp to recover silver by flota-tion . By this flotation process , higher silver recovery rate , greater production rate and higher concentrate grade can be arrived , and the gold can be enriched to recover at the same time .%研究了湿法炼锌常规浸出工艺下酸性浸出渣的浮选性质，提出并讨论了从锌常规浸出渣中浮选回收银的关键条件，认为锌常规浸出的酸浸矿浆直接作为原矿浆用于浮选回收银的工艺路线优势明显，银浮选回收可以达到较好的回收率、产率和精矿品位指标，并能在浮选中同时有效富集回收金。
