Magnetic separation - Wikipedia

Weak magnetic separation. Weak magnetic separation is used to create cleaner iron-rich products that can be reused. These products have low levels of impurities and a high iron load. This technique is used as a recycling technology. It is coupled with steelmaking slag fines as well as a selection of particle size screening. Equipments

Slag - Wikipedia

Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.
