The results show that the total zinc amount entering into the blast furnace is nearly balanced with the overflowing amount of zink in stable operation conditions; the main factor which effects on Zn load of blast furnace is the Zn content of sinter ore ,it can reach to 50% of the total content,the Zn content of the BF is carried out by sluage ,it brings out 70% of total expenditure.

结果表明：在高炉正常的冶炼条件下，进出高炉的锌的总量基本上保持平衡；入炉原燃料中，以烧结矿带入的锌最多，可以达到50%以上，而在锌的支出方面则主要通过污泥，几乎可达到支出总量的70%左右。

Enterprise development directions: one, to play a factory in the Zinc and Zinc Products zinc series of advantages to develop products; II, with enterprises as the hot-dip galvanizing industry supply fluxing agents and the advantages of providing technical services development and hot-dip galvanizing and surface works chemical products.

企业发展方向：一、发挥工厂在锌产品和锌盐方面优势开发锌系列产品；二、以企业为热镀锌行业供应助镀剂和提供技术服务的优势开发与热镀锌及表面工程相关的化工产品。

The results show that the dissolution process of prefabricating alloy can be divided into two periods when the temperature of zinc melt is below the melting point of aluminum.Firstly,zinc melts infiltrates into the prefabricating alloy and then Zn-Al-TiC alloy forms in the surface layer of the prefabricating alloy.Secondly,the Zn-Al-TiC alloy of this alloy surface layer begins to dissolve to the zinc melt.

结果表明：当锌熔体温度低于铝熔点时，预制合金的溶解可分为两个阶段：第一阶段为液态锌向预制合金中浸渗，并在预制合金表层内形成Zn-Al-TiC合金；第二阶段为预制合金表层内的Zn-Al-TiC合金开始溶解并进入锌熔体。

Due to the sulphidizing amine flotation of zinc oxideminerals being sensitive to the slimes and soluble salts, the problems of lowseparation indexes, complicated flotation circuit and reagent types, high consumptionand cost are still not solved in spite of lots of research and practice on the flotation ofzinc oxide ores.

由于氧化锌矿的胺法浮选对矿泥和可溶盐较为敏感，因此，尽管国内外对氧化锌矿的浮选工艺作了大量的研究和实践，仍然未能解决氧化锌矿的选别指标低、工艺流程及药剂品种复杂、成本高等问题。

Process and mechanism of electrodeposited Zn-Fe-Si02 composite coatings were studied, including some contents as follow: Potential-pH plots of Zn-H2O and Fe-H2O systems were drawn, and the thermomechanical analysis was made. Results showed that the region of zinc and iron's codeposition was wide, which provided theoretic basis for electrodepositing Zn-Fe alloy. But the balance potential of zinc was greatly different from iron's, so in order to make zinc and iron codepositing, some complexant must be added into electroplating solution.

本文研究了电沉积Zn-Fe-SiO_2复合镀层的工艺和机理，主要包括以下几个方面：绘制了Zn-H-2O系和Pe-H_2O系的电位-pH图，并对其进行了热力学分析，结果表明，锌和铁发生共沉积的区域很大，这就对电沉积Zn-Fe合金的可能性提供了理论依据，但是锌和铁的平衡电位差别较大，所以，必须在镀液中添入一定量的配合剂才能使锌铁产生共沉积。

Accordingly,the ammonium sulphide method followed by combined process of magnetic separation-flotation was adopted in this experiment and the zinc concentrates with grade of 36 86%and 36 51%and recoveries of 54 51%and 48 96%were obtained respectively.

试验采用了硫化胺法和磁—浮联合流程浮选氧化锌，可获得锌品位分别为 36 86%和 36 51 %、回收率为54 51 %和 48 96%的锌精矿。
