presented lower extraction values. Key words: reductive leaching; zinc ferrite; zinc; indium; sphalerite concentrate 1 Introduction Indium is an important metal used in electrical industries extensively [1,2]. It is mostly associated with zinc ores, and has therefore been recovered as a by-product of zinc metal processing operations. The modern extractive metallurgy of zinc is dominated......
高品质锌粉具有规则的球形形貌,杂质含量低(＜50×10-6),总锌和金属锌含量高,分别≥99.5%和≥98%.精馏温度,液态锌的蒸发温度以及冷凝器的温度等工艺参效是影响高品质超细活性锌粉质量的主要因素. 关键词:金属材料; 高品质超细锌粉; 精馏-冷凝; 电炉粗锌; 高效复合冷凝; metal material; high quality super fine zinc dust; distilLation-condensation; electric furnace crude zinc; efficient multiple condensation; [全文内容正在添加中] ......
