提出了一种通过熔析精炼方法从金属杂质(例如铁)中纯化锌熔体的提取剂选择方法.采用一个提取阶段的周期性过程公式计算锌熔体精炼的有效性,并研究所选添加剂从铁杂质中提纯锌熔体的提取能力.实验结果表明,从铁杂质中纯化非合金锌,可以采用硅作为提取剂,且提取效率最高;精炼锌合金可以采用铝和锰作为提取剂.“,”This paper proposes the methodology of the selection of extracting additives for purification of zinc melts from metal impurities (for example from iron) by the liquation refining method,introduces the calculations of the effectiveness of zinc melts liquation refining with an assessment of possibility using a formula of extracting periodic process for one stage of extraction,and underscores the investigation into the extracting ability of the chosen additives for purification of zinc melts from iron impurity.The experimental results show that the highest efficiency of the purification of unalloyed zinc from iron impurity was achieved by using silicon as an extraction additive.It was recommended to use aluminum and manganese as extracting additives for zinc alloys refining.
