High-intensity magnetic separators employ higher field strength up to 20,000 Gauss. This method is applied to separate weakly magnetic iron minerals such as hematite and goethite from the non-magnetic silica and alumina-bearing gangue materials. In many iron ore mines, wet high-intensity magnetic separation is being preferred in the ...

In India, the total resources of iron ore are estimates as 28.52 Billion Tonne and the distribution between hematite and magnetite have been estimated as 17.96 Billion Tonne and 10.55 Billion Tonne, respectively. However, inspite of available magnetite ore, the same have not been exploited due to its occurrence in eco-fragile / sensitive area and
