Manganese ore belongs to the weak magnetic minerals, which can be recovered by high-intensity magnetic separator. Xinhai applies the magnetic process to separate manganese ore, including two stages, rough separate the high-intensity magnetic ore and concentrate the medium intensity magnetic ore, thus improve the manganese grade by 4% to 10%.
The magnetic separation process of manganese ore can be applied to separate high phosphate ore, high-silicon ore and low bixbyite ore.
Rough separate the high-intensity magnetic ore
Xinhai adopts special high-intensity ;magnetic separator of manganese ore to remove impurities preliminary, then uses spiral classifier to classify rougher concentrate, rougher tailings directly discharge ;into the tailings thickener at last.
The underflow of the classifier been delivered into the magnetic separator to concentration, and the overflow been dewatered at the thickener.
The concentration overflow discharged into the backwater system, the concentration underflow converged with the concentration becoming the concentrates.
