所谓水法冶金,就是把铁放在胆矾(即天然硫酸铜)溶液中,使胆矾中的铜离子被金属铁取代,而还原成为单质铜沉淀下来的一种产铜方法。这种方法,在我国首先发明并应用于生产实践中,是中国古代科技在化学方面的一项突出成就。水法冶金与火法冶金相比,有下列优点:第一,可以就地取材,普遍推广。在胆水多的地方,便可设置铜场,进行生产,而且设备简单,操作技术容易掌握,成本低廉。第二,可以在常温 The so-called hydrometallurgical, that is, the iron on the cholesta (that is, natural copper sulfate) solution, the cholesta in the copper ion is replaced by metallic iron, and reduced to a single element copper precipitation down a copper production method. This method, first invented and applied in production practice in our country, is a prominent achievement of ancient Chinese science and technology in chemistry. Hydrometallurgy and pyrometallurgical compared to the following advantages: First, you can draw on the spot, the general promotion. In places with a high concentration of chondroitin, a copper field can be set up for production, and the equipment is simple, the operation technique is easy to grasp, and the cost is low. Second, it can be at room temperature
