MINERAL SEPARATION
The Huate magsep plant at the Roy Hill iron ore operation in WA
layout is simple, occupying a small space, and can save more than 40 % of the project investment.
Also unveiled was Huate’ s CTF-1830 dry powder ore magnetic separator. Designed specifically for dry preconcentration of lowgrade magnetite( with moisture content < 3 % and particle size ≤ 16 mm), it is equipped with a high-performance NdFeB magnetic system and an adjustable drum speed( 1-20 m / s) to improve concentrate grade; it processes 330-400 t of dry ore per hour, reducing water usage and operational costs, making it an ideal choice for water-scarce mining areas.
A third major launch was the TCY- 1530 high-intensity magnetic titanium preconcentrator. Focusing on dry separation of low-grade ores( with particle size ≤ 3 mm), its 1,000mT magnetic field strength enables precise separation of magnetically differentiated minerals such as ilmenite and chromite; the non-metallic drum design reduces energy loss, and the ceramic surface protection extends equipment life; it processes 120-150 t / h, enhancing the efficiency of mineral concentration.
For export projects, a stand out example for Huate is with Australia’ s Roy Hill mine, part of Hancock Iron Ore, which has an annual production capacity of 55 Mt. Back in August 2018, Huate passed the owner’ s review with it says its strong technical strength and talent advantages. and eventually became the supplier of the magnetic separation equipment for the Ultrafine Iron Recovery Project at Roy Hill. The equipment for this project included 14 sets of LHGC-3000 vertical ring high gradient magnetic separators and 14 sets of CTB-1540 cylinder magnetic separators. The total value of the contract amounts to more than US $ 10 million. During the
project implementation process, Australian standards were used and all aspects of technical design, raw material procurement, processing and manufacturing, final assembly and commissioning, inspection and testing were strictly controlled to ensure the smooth implementation of the project.
South Africa’ s MAGQUIP’ s outside the box thinking
MAGQUIP, based in Roodepoort, South Africa says that not all suspension magnets perform the same- even if they look similar.“ The real difference lies in the magnetic circuit design. Our Tri-Pole permanent suspension & overband magnets use a three-pole magnetic configuration that distributes magnetic strength across the entire working face of the magnet. Unlike conventional single- or twin-pole designs- where magnetic pull can weaken at the centreline or outer edges- the Tri-Pole circuit creates a broader, deeper-reaching magnetic field”. Why does this matter in real-world conditions? The company says it brings a stronger centreline pull where material burden is deepest; improved recovery of smaller or irregular ferrous contaminants; more consistent performance at higher suspension heights, plus reduced drop-back at higher belt speeds. MAGQUIP:“ Magnetic field distribution is often more important than peak strength. A uniform field across the belt width improves capture efficiency under variable feed conditions.”
The company also recently announced the successful completion and commissioning of its HEMASORT Dry Magnetic Separator on a hard-rock lithium operation- a project that the OEM says marks a genuine first for the industry.“ Removing iron contamination in hardrock lithium is notoriously challenging, especially when balancing strict product specifications with demanding production tonnages. Our team delivered a solution that achieved both: meeting the client’ s grade requirements while keeping them firmly on target for throughput. Even more impressive is the pace of delivery. The entire plant was scoped, designed, and built in just five months- a remarkable turnaround that showcases what can be achieved through committed collaboration and focused engineering.” MAGQUIP worked closely with engineering group Lycopodium on the project in terms of the plant build.“ This installation is also the first of its kind- a dry magnetic upgrade system purpose-designed for iron removal in a hard-rock lithium process. No water. No added complexity. Just smart engineering and high-intensity magnetic performance doing exactly what it was designed to do.”
Finally, together with its partners at Gravitas Minerals, MAGQUIP has developed the SUPERMAG Wet Belt Separator – a cutting-edge solution for Wet High-Gradient Magnetic Separation requirements.“ This technology is designed for the concentration of valuable minerals and the removal of paramagnetic impurities from slurry streams. By passing a moving belt through a powerful permanent rare earth magnetic field, the SUPERMAG attracts fine and weakly magnetic particles – such as iron oxides – and carries them up the inclined belt, while non-magnetic materials are washed down the belt & discharged into a separate launder.”
Applications include silica / quartz / chrome beneficiation – improving quality by removing iron-bearing contaminants plus in hard-rock lithium flowsheets – an increasingly critical step in battery mineral processing flowsheets for wet processing.
