MAGQUIP HEMASORT High-Gradient Magnetic Separator

Exclusive Magnetic Roll Technology for Dry Upgrading of Hematite, Manganese, and Iron Removal in Lithium Ores

The MAGQUIP HEMASORT is a next-generation high-gradient magnetic separator built around a proprietary magnetic roll assembly, designed specifically for the dry processing and upgrading of coarse-grained hematite and manganese ores — and the selective removal of iron-rich contaminants in hard rock lithium deposits.

Unlike conventional rare earth roll separators, the HEMASORT employs a uniquely engineered magnetic roll configuration. While not patented, the design is exclusive to MAGQUIP, and no other manufacturer currently uses or replicates the magnetic system or internal assembly developed for this unit. The result is a new level of performance in dry magnetic separation — with application results that competitors have yet to match.


Dry Separation Reinvented for Iron-Rich Ores

The HEMASORT was purpose-built for dry, high-throughput beneficiation of:

  • Lump hematite ore

  • Manganese ores 

  • Chromite ores (CHROMSORT variant)

  • Iron silicate gangue minerals in spodumene and lithium-bearing pegmatites

It enables operators to process ores without water, crushing, or flotation, making it ideal for remote, arid, or in-situ mining applications where conventional wet circuits are economically or environmentally unfeasible.


High-Capacity Roll Design

The unit features a high-gradient roll with a 1500 mm wide effective separation zone, fed via an integrated vibrating feeder and short conveyor system. This design allows for uniform distribution and high material throughput — especially important for the processing of coarse particles up to 50 mm.

Material is fed from the hopper and vibrating pan feeder at a controlled rate on to the short belt conveyor. The ore travels along the conveyor belt towards the large diameter rare earth magnetic roll, particles are then influenced by competing centrifugal and magnetic forces.

Hematite or any other weakly magnetic iron oxide particles are pinned to the roll and travel around the roll periphery held in by the magnetic force.

Non-magnetic particles not influenced by the magnetic forces are thrown from the belt on their normal trajectory at a position on the roll where the centrifugal force overcomes the magnetic forces.

The magnetic roll consists of a series of rare earth permanent magnet rings sandwiched between carbon steel disks with optimal magnet and pole thickness configuration based on large particle sizes and is driven directly by a shaft mount geared motor which also drives the speed adjustable (VSD) conveyor belt.

The MAGQUIP HEMASORT separator will separate and upgrade dry, coarse weakly magnetic and material such as hematite and chromite.

The HEMASORT / CHROMESORT can handle feed rates of up to 200 tph depending on layer depth and bulk density.
