The iron ore produced from Iron Ore Mine is rich in iron content with low impurities. The iron ore is recovered in the form of lumps (40%) and fines (60%). The iron ore produced from the mine is transported to the crushing and dry screening at the crusher plant located for the final product recovery. The waste generated from the working pit is directly disposed to the dump areas located within the mining lease area. The crushed ore is passed through vibrato ring screens to yield three products namely +30 mm, -30 mm to +10 mm and -10 mm sizes.
Zenith is operating physical beneficiation plant comprising of one 150 tph capacity and one screen of 100 tph exclusively for dry of ore. The run-of-mine is subjected to gravity size separation at we pit for removal of fines and the oversize is transported to beneficiary plant for crushing. The crushed ore is passed through vibratory yield three products namely +35 mm; -35 to +10 mm and -10 mm +35 mm product is recycled to secondary crusher for -30 mm to +10 & – 10 mm. Thus only two final products are produced. The iron ore of greater than +10 mm (with greater than 64-67 content) as per consumers requirement is supplied to MMTC and -1 fines (> 64% Fe) to Cement plants.
Iron ore processing flow is the front physical manufacturing process in steeling making course. From the iron ore processing flow chart picture, we can see the iron ore process flow goes as follow:
Raw iron ore is exploded from the iron ore mines firstly. Then vibrating feeder will feed iron ores into the iron ore primary crusher crushing cavity, in which large size raw iron ore will be resized into iron ore sand. The iron ore sand is transmitted into secondary crushers by belt conveyors evenly and continuously. Then the out let of secondary crusher is carried into tertiary crusher, in which iron ore will be processed into powder size iron ore particles. Iron ore crushing process ended here.
When coarse iron ore powder fed into iron ore grinding mill, the iron ore grinding process starts. Zenith grinding production line processes iron ore into mm to μm degree powder which is quite fit for the next beneficiation process.
Iron ore beneficiation process is used increase the purity to 59% or more. Iron ore beneficiation process is important. It makes the calcine process easy with higher efficiency. The outlet of beneficiation process is fine ore.
After sintering with high temperature, iron pellet ore will be calcined in the blast furnace and finally processed into iron streel.
