The rock from the crushing plant needs to be reduced typically from the range 1–10 mm down to 0.05–0.1 mm in order for the flotation to work efficiently. For this size reduction, from 1 to 10 mm, down to the range 0.05–0.1 mm, wet tumbling mills are often used, in combination with hydrocyclones for size classification.
The complete plant consists of the below machines: vibrating feeder, jaw crusher, belt conveyor, cone crusher, double roller crusher, vibrating screen, dry magnetic separators, and ball mill. Raw ore information as below: Iron rock ore, magnetite Fe3 O4. Rock after crushing to 5mm for release inside the iron.

Hematite and magnetite are the most prominent iron ores. Most of the high-grade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− 31.5 + 6.3 mm) and fines (approximately − 6.3 mm) products.
iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive magnetic properties.
