For this,experimental study was made on a new process of potential-controlled preferential flotation in a sequency of copper,lead and zinc,which used LP-01 as collector for copper mineral,DDTC as collector for lead mineral,copper sulfate and butyl...

为此，以LP-01为铜矿物的捕收剂、乙硫氮为铅矿物的捕收剂、硫酸铜和丁黄药为锌矿物的活化剂和捕收剂、石灰为矿浆电位调整剂，并在选铜、铅时配合使用铅矿物的组合抑制剂ZnSO4+YN，对该多金属复杂硫化矿进行了电位调控铜、铅、锌依次优先浮选新工艺试验研究，获得了含铜21.74%、铜回收率62.31%的铜精矿，含铅61.23%、铅回收率55.07%的铅精矿和含锌56.43%、锌回收率90.02%的锌精矿。

Process of flotation of acture ore is the following: firstly, adding Na_2CO_3, ZnSO_4, CSU-1 to the pulp while grinding, and thus in this condition of low Eh, marmatite is inhibited; Secondly, adding CSU-1 to the pulp out of grinding machine, then amesonite and iron sulfur mineral can be flotated using diethyldithiocarbamate as collector; High quality lead and antimony concentrate can be got by adding CSU-1 and calcareousness; Lastly, marmatite is flotated by adding calcareousness, CuSO_4, xanthe, and D-250 to get zinc concentrate.

小型试验研究表明，首先在脱硫粗选作业只加入适量的Na_2CO_3、ZnSOO_4、和CSU-1至磨矿机，利用磨矿机的研磨和磨机中的低电位环境，使铁闪锌矿受到抑制，而最容易浮的脆硫锑铅矿和黄铁矿、磁黄铁矿等硫化矿物则依然具有可浮性；在磨机出来的矿浆中分别加入CSU-1进一步抑制易浮的铁闪锌矿，然后加入乙硫氮将脆硫锑铅矿和硫化铁矿快速浮净，加入石灰和CSU-1，浮选分离出高质量的铅锑精矿；接着添加石灰、CuSO_4、黄药及2~#油选别铁闪锌矿。

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。
