Specifications: Feed size is usually between1.16 mm and 74 μm (14 and 200 mesh), but with iron ore, up to 2.3 mm (8 mesh) material may be treated to make a rougher concentrate, provided a high pulp density is used. Solid content of approximately 15-35% solid concentration combined with wash water produces good results. REQUEST A QUOTE AND BROCHURE

In concentrator plants where the quality of ore is poor the magnetic and gravity separations are usually followed by a flotation process. It is very advantageous to bypass the flotation when the grade from magnetic separation is high enough. Additionally, the flotation process of quartz has different properties from other silicon-bearing minerals.
