Mexico 1,000t/d Iron Ore Processing Plant

Crushing and Grinding: The raw ore is crushed in a jaw crusher and a cone crusher to a particle size below 2 cm. It is then fed through a buffer hopper and a feeder into a ball mill, where it is ground to the target qualified particle size of -60 mesh (adjustable according to actual needs).

Screening and Grading: The ground material undergoes preliminary grading on a drum screen and is then pumped by a slurry pump to a cyclone. The cyclone separates coarse particles larger than 60 mesh (adjustable) and returns them to the ball mill through a return pipe for further grinding.

Magnetic Separation: Fine material below 60 mesh enters a drum magnetic separator (magnetic field strength of 2000 GS), which primarily removes all mechanical iron and some magnetic iron components. The product then enters a vertical ring high-gradient magnetic separator (electromagnetic, magnetic field strength of 10,000 GS) to further remove hematite (Fe2O3), effectively improving the iron grade.

Dehydration: The concentrate after magnetic separation enters a dosing concentrator for concentration, followed by a vacuum disc filter to reduce the concentrate moisture.

Collection: The dewatered concentrate is transported via a belt conveyor to the refined product area for storage. The entire production line is equipped with a high-efficiency thickener that collects and treats water used in various systems, enabling tailings sedimentation and clean water reuse, thus enabling water recycling.

Tailings Treatment: The tailings produced by sedimentation are conveyed by a slurry pump to a plate and frame filter press for separation of the tailings and water. The dewatered tailings are transported to a stockpile, and the filtrate is returned to the water system for reuse.
