Iron ore Processing technology

Iron ore Processing technology

Pure magnetite can be directly into the furnace iron making, but in the end still associated minerals are more simple, crushing and screening for magnetite some impurity content is high, the grinding magnetic separation concentrate to production, so the production process of iron ore processing mainly include: crushing, grinding, ore dressing three processes.

The first step: crushing and screening - closed-circuit three stage crushing

Iron ores silo by vibrating feeder evenly sent to large jaw crusher or mobile jaw crusher station are crushed; coarse crushed ore by screening the vibration sieve, by belt conveyor to the single cylinder hydraulic cone crusher in crushing; iron ore material crushed into the multi cylinder hydraulic cone type of crusher;

Processing Equipment

The second step: Milling

Will pass through the screening vibrating screen 0-12 mm powder evenly into the goal by grinding, sieving and spiral classifier, does not meet the requirements of being sent the ball mill to mill;

The third step: magnetic separation

Will meet the requirements of the iron ore dressing into the magnetic separator for high intensity magnetic separation, magnetic separation to remove debris;

The fourth step: drying

The resulting powder into the dryer drying can get iron concentrate.
