High Carbon-Ferro-Chrome from Slag DISSERTATION Prepared by Refilwe Kopong (0400537k) Submitted to School of Chemical and Metallurgical Engineering, Faculty of Engineering and the Built Environment, University of the Witwatersrand, Johannesburg, South Africa Supervisor(s): Prof S. Ndlovu and Prof V. Sibanda June, 2015

The slag is separated into coarse and fine size fractions with the coarse (-25 +6ram) being treated in a two, stage air pulsed jig. This jig produces directly salable coarse alloy and a middlings fraction for recycle, with recoveries in excess of 95% of liberated metal being achievable. In other plants (-30 +3ram) is jigged in the coarse section.
