Although the iron concentrate reached the target design of 1.864 million tons, the grade of raw ore was dropped to 35%, which was much lower than the original design. Therefore, the mine owner entrusted Xinhai to finish the later iron ore dressing process, and achieve the initially expected effect.
Artus Corp.s steel separator discs are precision manufactured to your exacting specifications, including taper and thickness. Made from the finest steel to a maximum hardness of 58/60 Rockwell C , steel separator discs from Artus guarantee you longlasting, dependable performance at competitive prices.
This mine processed by Xinhai iron ore mining team began to strengthen the plan of research schedule for its development to get the pellets with 63.8% iron and 7.5% SiO2 as well as the iron concentration with SiO2 7.0% to 7.5% from the magnetite ore with with 22% magnetite in the iron ore mine which is very satisfactory at that time.
Process Introduction There are a lot of iron ore in nature, which containes highly quantities of hematite or magnetite.The mainly iron ore beneficiation method is magnetic separation and flotation separation,so the mainly used iron ore equipments are flotation machine, magnetic separatior,efficient thickener,press filter,slurry pump,feeder, agitation tank and belt conveyor etc.
In order to take advantage of the mineral resources, the iron ore reverse mining or beneficiation process came into being. This essay will focus on the iron ore reverse flotation. Flotation technology is very common in the iron ore beneficiation. The conventional mining or beneficiation process has a poor effect on the removing the impurity ...
It usually achieves the classifying efficiency by adjusting the operation factors. Xinhai is a professional manufacturer of iron ore cyclones. According to the features of the iron ore cyclones, it adopts the super wear resistant rubber Xinhai as the cyclones lining to prolong the service life of the iron ore cyclones.
Inside the ball mill, the crushed iron ore will grind the ore to about 0.2 mm with 3 inch steel balls. 3.This iron ore slurry is pumped to the agitation tank. This iron ore slurry is finally pumped to the flotation machine with the fine sulfide ore going to froth flotation cells for recovery of iron.
The iron ore resources are featured with more lean ore, less rich ore, more associated ore and complex ore composition. There are a variety of iron ores in nature, mainly including magnetite, haematite, limonite, siderite, so the beneficiation of iron ore needs a suitable process to improve the economic benefit.
