Mincon Employs Pelletizer to Beneficiate Beryllium Ore

Today's largest producer of domestic beryllium oxide, Mineral Concentrates & Chemical Co., Inc., has recently disclosed the basic outline of its unique process of beneficiating beryllium ores to high purity BeO. This process, known as the Mincon process, is a thermic-flotation scheme which has reportedly resulted in a recovery ratio exceeding 90% and in allowing up-grading of beryllium concentrates to as high as 33%. Mincon borrowed a step from the iron ore industry by introducing a pelletizing and sintering stage in their flow sheet at the company's mill at Loveland, Colo. This mill, now operating at full-capacity with three-shifts a day, is still undergoing some minor changes and adjustments in the equipment and chemical reagents.
