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.
A manganese ore project of Xinhai, its main ore is Rhodochrosite and Ca rhodochrosite, then Calcite. Gangue including quartz, chalcedony, carbonaceous and clay, etc. Xinhai contracts the whole designation of the mineral production line, and adopts the process of rough separate the high-intensity magnetic ore and concentrate the medium intensity magnetic ore, which guarantee the ore grade can reach 38%, and the recovery rate reach 74%.
Xinhai can provide the whole EPC service of mineral design and research, equipment manufacture, installation and commissioning, personnel training according to the property of the raw ore. Xinhai has already achieved many designation and reformation of the manganese ore project, a project of aboard is a great success. That raw ore including high phosphorus, high silicon, and low iron lean manganese carbonate, 20% manganese ore contained.Rhodochrosite is the main manganese ore, apatite is the main harmful element, quartz, and clay is the main gangue minerals. The magnetic separation production line of the manganese ore reach desired effects, and the concentration grade reach 35%, and the recovery rate reach 76%.
