Hematite ore selected from the group selected from devices belonging miners process technologies, and in particular relates to a mineral breaker screening, grinding and classification, dephosphorization agent float mineral processing, high grade ore hematite is selected from phosphorus miners arts, new The hematite beneficiation process is characterized in that the high-phosphorus hematite ore is crushed and sieved , and the dephosphorization agent is applied after grinding and classification, and the purpose of dephosphorization and desiliconization is achieved through two-stage flotation , and then the spiral chute is used in combination. slag and shaking for roughing, selected scavenger, to improve quality and reduce iron elemental phosphorus, to obtain a content of silicon will meet the requirements of the smelting process into the furnace ore flotation three-step flotation tailings was added after the magnetic separator obtained by the above process and boron iron ore concentrate hematite two products reselection process, more or intensity magnetic separation and flotation beneficiation process and use, and there have been a weak magnetic roasting Magnetic separation process. First be mined ore jaw crusher preliminary crushing, after crushing to a reasonable degree of fineness via the hoisting machine, the vibrating feeder evenly into the ball mill, crushing the ore, milling by a ball mill. The ore fines ground by the ball mill enter the next process: classification. The spiral classifier cleans and classifies the ore mixture by the principle that the specific gravity of the solid particles is different and the rate of precipitation in the liquid is different. The mineral particles are fed into the flotation machine, and different drugs are added according to different mineral characteristics, so that the desired minerals are separated from other substances. The mined ore is firstly crushed by a jaw crusher, and after being crushed to a reasonable fineness, it is uniformly fed into the ball mill through a hoist and a vibrating feeder, and the ore is pulverized and ground by a ball mill. The ore fines ground by the ball mill enter the next process: classification. The spiral classifier cleans and classifies the ore mixture by the principle that the specific gravity of the solid particles is different and the rate of precipitation in the liquid is different. The mineral particles are fed into the flotation machine, and different drugs are added according to different mineral characteristics, so that the desired minerals are separated from other substances.
