采用单因素试验法研究了从镀锌灰中热酸浸出锌及黄钾铁矾法除铁。试验结果表明：在硫酸初始质量浓度为150 g／L、浸出温度90℃、浸出时间3 h、液固体积质量比6∶1条件下，锌浸出率在97％以上；用黄钾铁矾法除铁，在温度90℃、反应时间3 h条件下，铁去除率在98％以上。
採用單因素試驗法研究瞭從鍍鋅灰中熱痠浸齣鋅及黃鉀鐵礬法除鐵。試驗結果錶明：在硫痠初始質量濃度為150 g／L、浸齣溫度90℃、浸齣時間3 h、液固體積質量比6∶1條件下，鋅浸齣率在97％以上；用黃鉀鐵礬法除鐵，在溫度90℃、反應時間3 h條件下，鐵去除率在98％以上。
채용단인소시험법연구료종도자회중열산침출자급황갑철반법제철。시험결과표명：재류산초시질량농도위150 g／L、침출온도90℃、침출시간3 h、액고체적질량비6∶1조건하，자침출솔재97％이상；용황갑철반법제철，재온도90℃、반응시간3 h조건하，철거제솔재98％이상。
By single factor experiments ,leaching of zinc using hot acid from zinc ash and removal of iron from the leaching solution by jarosite process were researched .The results show that the optimum conditions for leaching zinc are determined as follow s initial acid concentration of 150 g/L ,leaching temperature of 90 ℃ ,ratio between liquid volume and solid mass of 6∶1 .At the optimum conditions , the leaching rate of zinc is more than 97% .Removal of iron is over 98% under the conditions of temperature of 90 ℃ ,reaction time of 3 h .
