锌渣

The preparation of Ni-Zn ferrite from sodium jarosite residue was studied.

摘 要：对黄钠铁矾渣制备复合镍锌铁氧体进行研究。

Sludge of Pan Steel were firstly disposed by mineral seperation and then the mill tailings of sludge were reduced by pyrometallurgy process to reclaim zinc, and iron in the slag tails were reclaimed by magnetic seperation.

采用选-冶流程处理攀钢瓦斯泥，经选矿后的瓦斯泥尾矿采用火法冶炼回收其中的锌，火法处理后的尾渣经磁选回收铁。

This paper describes experimental process and results for recovering zinc from flue dust and analyses the technical features and economic superiority of chlorine removal from copper residue .

介绍了烟尘中锌的回收试验过程及结果，分析了铜渣除氯的技术特点和经济优

And reduce the dissoluble zinc in the slag.

降低矾渣中可溶性的锌。

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。

By various means of analysis and test,several layers of sticking kiln crust in zinc leached residue volatility kiln were made clear for their chemical compositions,phase components,and physicochemical properties,such as smelting point,viscosity,etc.

采用多种分析检测手段对锌浸出渣挥发窑内挂结的几层窑皮进行测试和化验，确定了其化学成分、物相组成、熔点和黏度等物理化学性质；深入分析了各层窑皮的挂结机理。

The result shows that sulphur in the raw material is fixed in the slag in the form of sodium sulphide during smelting, main metals of lead and antimony and precious metals are concentrated in the metallic phase while zinc, indium and other associated metals existing in the slag.

在熔炼时原料中的硫元素全部以硫化钠的形式被固定在熔炼渣中，铅锑主金属及贵金属进入金属相，锌、铟等伴生金属元素进入渣相。

Studies have shown: The smeltery of Zhuzhou has a long way to go compared with famous zinc enterprises of foreign countries in the sulfur dioxide , gas of the greenhouse and heavy metal discharged.Zhuzhou smeltery should reduce the sulfur dioxide discharging density , raise the energy utilization ratio as the focal point of cleaner production and pollution control.

研究发现：株冶在二氧化硫、温室气体及重金属排放上，与国外著名锌企业差距明显，株冶应以浸出渣处理工序的低浓度二氧化硫排放与能源利用作为进一步清洁生产与污染治理的重点。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
