CPT Inc. has developed a flotation process for the production of Direct Reduction (DR) as well as Blast Furnace (BF) grade concentrates utilising column flotation technology. This process has been adopted by several major iron ore producers and current aggregate production is approximately 50 MTPY of DR grade concentrates.
