Abstract
The quality of steel produced from scrap can be adversely affected because of the buildup of tramp elements in recycled scrap. The tramp element of greatest concern is copper because of its effect on steel quality, even in small percentage quantities. In this study, possibility of removal of copper from ferrous scrap by using $Cl_2$ gas is experimentally examined in a small size experimental apparatus. Synthetic ferrous scraps containing copper were reacted with $Cl_2$ gas in various atmosphere. The copper was chloridized and evaporated, whereas iron was oxidized and was not reacted with Cl2 and oxygen mixture gas.
