胆水炼铜,又称胆水法、水法炼铜,系指用铁等较活泼的贱金属从胆水(硫酸铜溶液)中置换出铜的炼铜方法,是中国古代在冶金技术方面一项重要发明。 秦汉之际开始盛行的炼丹术最早发现铁能够从硫酸铜溶液中置换出铜的化学反应,西汉《淮南万毕术》卷下就记载有“白青(即水胆矾)得铁则化为铜”。据北宋沈括《梦溪笔谈》引唐代《丹房镜原》(成书约在758～762年)的“信州铅山县有苦泉,流以为涧,挹其水熬之,则成胆矾,烹胆矾则成铜。熬胆矾铁釜,久之亦化为铜”记 Ganshiliang copper, also known as gall water law, water copper smelting, refers to the more lively base metals such as iron from gall water (copper sulfate solution) to replace the copper copper refining method is the ancient Chinese metallurgical technology An important invention. Alchemy began on the occasion of the Qin and Han dynasties found the earliest iron from copper sulfate solution can be replaced by the chemical reaction of copper, the Western Han Dynasty, “Huainan Wan Bi surgery” recorded under the “white blue copper”. According to the northern Song Shen Kuo “Meng Xi Bi Tan” lead the Tang Dynasty “Dan Fang Jing Yuan” (into the book about 758 ~ 762 years) “Shinshu Qianshan County have bitter spring, flow that Jian Jian, the water boil it, then into alum , Cookery alum is made of copper .Air alum iron kettle, a long time also into copper ”mind
