2013-12-24 · Mechanized mining operation along with its multiple advantages brought drastic changes in the ROM iron quality by increasing the fines and dirt. Surface property- based separation processes such as froth flotation and agglomeration are very selective in rejecting well-liber-ated mineral matters. However, efficiency of these proc-esses gets reduced if the feed contains disproportionate amount of composite particles. Surface based separation processes are very intricate, needs close attention and careful operation where as the conventional gravity- based separation
