Basic Principle
SLon vertical ring and pulsating high gradient magnetic separator (SLon VPHGMS) utilizes the combined forces of magnetic field, pulsating fluid force and gravity to continuously beneficiate weakly magnetic fine minerals. It is equipped with a unique pulsating mechanism possessing advantages of large beneficiation ratio and high recovery rate, and a matrix of vertical rings that are not easily clogged.
Application Areas
- Weakly magnetic minerals beneficiation, such as: hematite, limonite, ilmenite, wolframite, tantalum, niobium ore and so on.
- Removal of iron from and purification of non-metallic minerals, such as: quartz, feldspar, nepheline, fluorite, sillimanite, spodumene, kaolin and so on.
Features
- Vertically rotating rings and recoiling concentrates. Congestion of magnetic media equipped on both flat ring intensity magnetic separators and flat ring high gradient magnetic separators has been an unresolved technical problem in the world for decades. SLon magnetic separators are equipped with vertical rotation rings. For each set of magnetic medium, the separator washes mineral concentrates in the direction opposite to ore-feeding direction. Coarse particles without having to pass through magnetic media can be washed from the heap, so as to effectively prevente from magnetic media blockage.
- A pulsating mechanism for the slurry to drive the slurry and result in pulsating fluids. Under the action of pulsating fluid force, mineral particles in the slurry are always in a loose state so as to improve the quality of the magnetic concentrates.
- Flat ring high gradient magnetic separator imposes a stringent requirement for the ore sizes. With a unique magnetic system structure and optimum combination of magnetic media, SLon VPHGMS can deal with ore sizes up to 2.0 mm. This simplifies site grading operations and is with a wider range of adaptability

Taihe Iron Mine of Chongqing Iron and Steel, originally had a system of spiral chute and shaking bed for the rougher of ilmenite before flotation for the cleaner, in a process of recovery of ilmenite from the weakly magnetic tailings, but the recovery rate of titanium was very low, with only 10% of TiO2 recovery. In 2000, the Mine was installed with 4 sets of SLon magnetic separators which were combined with the original flotation process to form a new operation process of differential magnetic separation, re-grinding coarse ore, magnetic separation and flotation beneficiation, effectively recovering ilmenite with different ore sizes. The new process reached a comprehensive recovery of TiO2 increased to 47% while ensuring the titanium concentrate grade ≥ 47%. Currently, the Taihe Mine's production capacity of titanium concentrate has increased to 70,000 tons per year, from around 2,000 tons before transformation.

Heishan Iron Mine of Chengde Iron and Steel has a deposit of typically mixing magnetite with ilmenite. The tailings produced from beneficiation of magnetite contained 8 ~ 9% of TiO2. Several attempts were initaited to recover ilmenite in the past, but all could only produced a small amount of low-grade titanium concentrates, with disposing off most of the tailings. In 2004 Heishan Mine utilised 3 sets of SLon-1750 magnetic separators to successfully resolve the technical problems of beneficiation of its ilmenite. It had been to achieve the design goal of an annual output of 30,000 tons of TiO2 grade ≥ 46.5%, which can be used as the feedstock to produce high quality titanium dioxide.

Beneficiation of Manganese Ore
Most of China's manganese ores are low grade, so domestic manganese ore market can not meet its demand. A large number of manganese concentrates are imported from abroad every year. How to develop the use of domestic low grade manganese resources is in a top priority. Extensive research, testing and production applications in recent years have fully proved SLon magnetic separator can beneficiate effectively low grade manganese ore, showing the equipment has a good prospect in the manganese ore industry.
