摘要/Abstract

摘要： 从矿石的形成过程、晶体结构、浮选机理三方面对异极矿的性质进行了总结，考察了异极矿在形成过程中的影响因素及特点、晶体结构与矿石可浮性的关系，并着重介绍了异极矿与常用浮选药剂如黄药类、胺类、脂肪酸类、螯合剂类等的作用机理，分析了上述三方面特性之间的内在联系. 结果表明，异极矿在形成过程中常与粘土矿物混杂，使锌金属易损失在细泥中；Zn原子在晶格中的活性低，Zn2+迁移能力低，需预先硫化或延长硫化时间；螯合剂法有望为异极矿的浮选开辟新的方向，应进一步丰富螯合剂的选择、设计、合成相关理论体系，加大在降低药剂成本等方面的研究力度.

关键词: 异极矿, 形成机制, 晶体结构, 浮选机理

Abstract: Properties of hemimorphite were summarized from three aspects, the forming process, crystal structure and flotation mechanism of ore. The relationship between crystal structure and floatability was discussed, impact factors and characteristics of hemimorphite in forming process were also analyzed. The mechanisms between hemimorphite and commonly used reagents such as xanthate, amines, fatty acids, chelating agents etc. were also introduced, which reflects the inner connection of the characteristics of the three aspects mentioned above. The results showed that zinc is easily loss in fine slime because the hemimorphite is often mixed with clay minerals in the formation process. Pre-sulfidization or extended sulfuration time is needed for the activity of Zn atoms in crystal lattice and the migration ability of Zn2+ cations is low. Chelating agent method is expected to open up new directions for the flotation of hemimorphite. Moreover, theory system of selection, design and synthesis of chelating agents and research in reducing reagent cost should be enhanced.

Key words: hemimorphite, formation mechanism, crystal structure, flotation mechanism
