Ferrous scrap was dissolved in waste HCl sal. (concn. 18%) at 30-95 degrees C and oxidized with gaseous Cl(2) to FeCl(3) to study the kinetics of both processes. The dissoln. was controlled mostly by diffusion of HCl to the scrap surface. The oxidn. rate of FeCl(2) with Cl(2) was high but no exact statements on the process kinetics could be made.
