明代宋应星《天工开物》中有一段关于炼锌技术的记载,原料是炉甘石(菱锌矿,主要成分为碳酸锌ZnCO_3),燃料是煤饼,用泥罐外加热的方式进行冶炼,这是研究明代炼锌技术最重要、最基本的资料。但有的问题宋应星交代得不太清楚,因此引起现在人们对这一炼锌法工艺原理的意见分歧:有人认为是蒸馏法,也有人认为是迥流法。两说相同处是:都认为炉甘石受热后先分解成氧化锌(ZnO)和二氧化碳 In the Ming Dynasty, Song Yingxing “Heavenly Creations” contains a section on the technology of zinc refining. The raw material is calamine (calamine, the main component is zinc carbonate ZnCO_3), the fuel is briquette, and smelting , This is the study of the Ming Dynasty zinc smelting technology the most important and basic information. However, some problems Song Yingxing confused to explain, so now people are divided on the principle of this smelting process differences: Some people think that distillation, and some people think it is a different method. Two said the same place is: all think calamine heated first decomposed into zinc oxide (ZnO) and carbon dioxide
