研究了以水热浸出法和硫酸浸出法从砷碱渣中浸出砷，考察了浸出时间、浸出温度、液固体积质量比及硫酸浓度对砷浸出率的影响。试验结果表明：相同条件下，水热浸出效果明显优于硫酸浸出效果；水热浸出时，各因素对砷浸出率的影响顺序为浸出时间＞浸出温度＞液固体积质量比，而硫酸浸出时，各因素的影响顺序为液固体积质量比＞硫酸浓度＞浸出温度＞浸出时间；在浸出时间30 min、浸出温度40℃、液固体积质量比12∶1条件下，砷的水热浸出率为78．12％。
研究瞭以水熱浸齣法和硫痠浸齣法從砷堿渣中浸齣砷，攷察瞭浸齣時間、浸齣溫度、液固體積質量比及硫痠濃度對砷浸齣率的影響。試驗結果錶明：相同條件下，水熱浸齣效果明顯優于硫痠浸齣效果；水熱浸齣時，各因素對砷浸齣率的影響順序為浸齣時間＞浸齣溫度＞液固體積質量比，而硫痠浸齣時，各因素的影響順序為液固體積質量比＞硫痠濃度＞浸齣溫度＞浸齣時間；在浸齣時間30 min、浸齣溫度40℃、液固體積質量比12∶1條件下，砷的水熱浸齣率為78．12％。
