Whether it’s processing high volumes of iron ore, or removing micron-sized ferrous or paramagnetic contaminants from valuable minerals, Eriez offers a complete range of continuous and batch magnetic solutions for wet processing. In hard rock mining, specialized magnetic equipment improves ball mill efficiencies by removing worn steel media fragments or using them as a protective liner.

Similar to the equipment used in wet processes, Eriez uses drum, roll, pulley and filter type magnetic separators in varying degrees of intensity to process dry minerals. These processes require conveyors, feeders and belts to present the material to the magnetic separators in underbelt, overbelt or gravity-fed applications.
