A new technique for removing copper from iron-based scrap has been proposed. When iron-based scraps containing copper were placed in atmosphere controlled by oxygen-chloring gas mixtures, copper was chloridized to evaporate, whereas iron was oxidized to remain in the form of solid. The evaporation rate of copper chlorides was determined by the transport of chlorides across the boundary layr. Thermodynamic and kinetic consideration gave the optimal condition for removing copper, that is, the temperature of 1100K and the gas composition of O2-10%C12.

已经提出了一种从基于铁的废料中去除铜的新技术。当将含有铜的铁碎屑放入由氧气载体混合物控制的大气中时，将铜氯化以蒸发，而铁被氧化以保持固体形式。氯化铜的蒸发速率是通过氯化物跨边界层的转运确定的。热力学和动力学考虑给出了去除铜的最佳条件，即1100K的温度和O2-10％C12的气体组成。
