In magnetite-containing rock, there is another possibility of separating gangue and iron ore. As the name magnetite already suggests, this type of iron ore is a magnetic rock. This allows the ground ore to pass relatively easily through magnetic separators, where the ferrous rock is separated from the rest of the gangue (magnetic separation).

Magnetic Separation. Figure 3 shows the variation of iron purity and recovery in the magnetic concentrate obtained from magnetic separation at a different intensity, and it is observed that the iron grade falls and recovery increases with an increase in magnetic intensity. It can be attributed to the accumulation of quartz and alumina impurities adhered to the feebly magnetic hematite phase.

“When separating the iron ore from the waste becomes too difficult, mining companies will dispose of the tailings in a dam.” The chemical additive is added to slurry – a semi-liquid mixture that contains valuable iron particles suspended in water – and works by separating the iron ore from impurities in the slurry.
The abundant refractory titanomagnetite (TTM) provides a cheap alternative source of iron, but this ore contains impurities and is difficult to process to make suitable concentrates for the blast furnace. In this study, reduction roasting of a primary TTM concentrate followed by magnetic separation …
Nov 10, 2017 1. Introduction. Hematite (α-Fe 2 O 3) is widely distributed in various rocks and is one of the most common and abundant iron oxide minerals in soil (Zhang, 2007).However, it cannot be used in iron and steel industry without preliminary beneficiation due to its low grade. Many researchers have investigated the separation of iron minerals from gangue minerals by froth flotation process (Luo et ...
