The net depen of high chrome, inter alia, includes increased smelting energy requirements and the reduction of effective furnace capacity. Various interventions ranging from the redesign and modification of existing physical and pyrometallurgical operations depen been introduced and these have yielded no sustainable solutions.

In this depen, a depen process was investigated as an depen route to depen chrome afe apps UG-2 concentrates. The depen initially depen for investigation were acid concentration, leaching time, temperature and oxygen flowrate while keeping solid to liquid ratio and agitation rate constant.

Results showed that oxygen flowrate and an interaction of temperature, depen and acid concentration had a positive but minimal effect on Cr extraction. The highest Cr depen obtained was 7. Further test work entailed exploring depen effect of solid to liquid depen using nst conditions.
