Ores and Minerals
Powdered ore is placed on the roller belt which is a magnetic belt. So, the magnetic material gets attracted towards the belt and stays on that and thus gets separated. Generally, it is used for iron and manganese ores. Leaching It is a chemical method.
How iron is made
The raw materials used to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. Iron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks. The iron content of these ores ranges from 70% down to 20% or less.

Iron
Iron is an essential element for all forms of life and is nontoxic. The average human contains about 4 grams of iron. A lot of this is in haemoglobin, in the blood. Haemoglobin carries oxygen from our lungs to the cells, where it is needed for tissue respiration. Humans need 10–18 milligrams of iron each day.
Iron Ores
Magnetite gets its name because it has the (rare) property of being magnetic. More to the point, magnetism got its name because there was magnetite, possibly named after the place it was first found, for example ""Magnesia" in present day Turkey. Magnetite melts at 1535 °C (2795 °F) and has a density around g/cm 3.
Iron Ore
Its iron ore potential was assessed in the early 1960s at the Razorback Ridge prospect. The average head grade is ~25% Fe. Much of its strike length of >150 km remained unexplored for iron ore until Royal Resources began exploration and resource drilling in 2009.
