The present invention adopts ammonium salt solution as leach, and adopts the liquid-phase oxidation activating agent formed from surfactant sodium ligno-sulfonate or sodium dodecyl sulfonate, liquir phase oxidation catalyst Cu(2+) and sulfur-extracting agent tetrachloroethylene to implement quick leaching process of sulkfide mineral in gas-liquid-solid three-phase reactor, all the sulfurs contained sulfide in mineral powder can be converted into elementary sulfur and sulfuric acid radical, the contained zinc, copper, nickel, cobalt, lead, cadmium and silver can be changed into soluble salt, and fed into leach or remained in the leaching out slag.

本发明涉及的有色金属硫化矿的铵盐液相氧化直接浸出方法，其特征在于：采用铵盐溶液作浸出剂，采用由表面活化剂木质磺酸钠或十二烷基磺酸钠，液相氧化催化剂Cu2+、萃硫剂四氯乙烯组成的液相氧化活化剂，在气液固三相反应器内，实现硫化矿的快速浸出过程，矿粉中各种硫化物所含的硫转变为单质硫和硫酸根，所含的锌、铜、镍、钴、铅、镉、银等变成可溶性盐类进入浸出液中或留在浸出渣中，消除传统流程中二氧化硫，硫化氢，氮氧化物及含砷含汞含铅等有毒烟气的排放。
