摘　　要：采用盐酸作为浸取试剂,从金矿尾渣中浸取出砷。考察了盐酸的用量、浸取时间、液固比、以及温度条件对砷浸出率的影响,通过正交试验找出砷浸出的最佳工艺条件,对于1g尾渣,盐酸的用量为0.8mL、振荡浸取时间17min、液固比20:1、以及温度为25℃。所用试剂廉价易得,设备简单,操作方便,实现了金矿尾渣中砷的高效浸取。In this paper, leaching of arsenic form gold tailing by HCl was studied. The influence of amount of hydrochloric acid, reaction time, liquid-solid ratio and temperature was investigated. Then using the orthogonal test confirm the preferable turn project.For 1 g gold tailing,under the condition of hydrochloric acid 3mL,reaction time 17min, liquid-solid ratio 20：1 and 25℃ .With easy to get low-cost reagents,cheap simple equipment and easy operation,has realized the As high-leaching.
