In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (ore concentrate) and a waste stream ().There are many different types of beneficiation, with each step furthering the concentration of the original ore.
Complementing the ALS Iron Ore Technical Centre investment is a 3,600m2 sample preparation facility located in the Perth suburb of Wangara. This high volume sample preparation facility supports the ALS Iron Ore Technical Centre analytical capacity, current and future, to remove bottle-necks associated with sample preparation.
Thankfully technology already exists for the purpose. This process of increasing the grade of iron ore by exclusively processing it by different physical and chemical methods is called 'Iron Ore Beneficiation'. Iron ore beneficiation uses the fact that the physical and chemical properties of the ore mineral and the impurities differ.
