酸浸酸浸acid leachingSUGnjln酸浸(a cid leaching)用无机酸的水溶液作浸出剂的矿物浸出工艺。它是化学选矿中最常用的浸出方法之一。硫酸、盐酸、硝酸、亚硫酸、氢氟酸及王水等均可作为浸出剂，其中应用最广的是硫酸。稀硫酸为弱氧化酸，可用于处理含大量还原性组分(如有机质、硫化物、氧化亚铁等)的矿物原料，硫酸价廉易得，设备防腐蚀间题较易解决，硫酸溶液具有较高的沸点，常压下可采用较高的浸出温度。热浓硫酸为强氧化剂，可将大部分硫化矿物转变为相应的硫酸盐。盐酸的反应能力比硫酸强，可浸出某些硫酸无法浸出的含氧酸盐矿物，但盐酸的价格较高，易挥发，劳动条件较差，设备的防腐蚀要求比硫酸高。硝酸为强氧化酸，价格较高，设备防腐蚀要求较高，一般不单独用作浸出剂，常用作氧化剂。中等强度的亚硫酸具有还原性，常用于浸出含氧化性组分的物料(如二氧化锰、锰结核等)，其浸出选择性较高。氢氟酸常用作钮妮矿物原料的浸出剂。王水主要用于浸出贵金属，使铂、把、金转入浸出液中，而锗、钉、俄、铱、银等则呈不溶物留在浸出渣中，然后用相应的方法将它们分离为单一产品。酸浸可分为简单酸浸、或化酸浸和还原酸浸三类。简单酸浸采用弱氧化酸作浸出剂，用以浸出某些硫化矿物、金属氧化物和某些含氧酸盐矿物。氧化酸浸则采用氧化酸或弱氧化酸加氧化剂作浸出剂，可浸出大部分金属硫化矿物和某些低价金属化合物。还原酸浸采用还原性酸性溶剂作浸出剂，浸出某些高价金属氧化物或氢氧化物。热浓硫酸浸出及热压氧酸浸出金属硫化矿物的过程属氧化酸浸。
