South African yearly chromite production has been increasing at an average production of 1 500 000t in the past 5 years except in 2016 where there was a slight decrease of approximately 900 000t [5]. Conventional chromite processes achieve an average recovery of between 50 and 65%, which result in a mass yield of between 37 and 45%.
