D.R.I. Fines. Direct-reduced iron (DRI), also called sponge iron is produced from the direct reduction of iron ore (in the form of lumps, pellets or fines) to iron by a reducing gas produced from natural gas or coal. Few ores are suitable for direct reduction. Reduced iron derives its name from the chemical change that iron ore undergoes when it is heated in a furnace at high temperatures inTailings Mineral Industry SolutionMagnetite iron ore particles are separated by the magnetite separator from the gangue (waste material) minerals in the cobber magnetic separators. This material flows to the ball mill for further size reduction. Material from the ball mill flows to the cleaner magnetic separators.HPGR High Pressure Grinding RollsJul 13, 2016· A Cerro Verde expansion used a similar flowsheet as the 2006-commissioned circuit to triple circuit capacity.
