Available world iron ore resources. Iron is the most abundant element on earth but not in the crust. [citation needed] The extent of the accessible iron ore reserves is not known, though Lester Brown of the Worldwatch Institute suggested in 2006 that iron ore could run out within 64 years (that is, by 2070), based on 2% growth in demand per year.
1. Single magnetic iron ore. The iron ore in the single magnetic iron ore is mostly magnetite. Because the magnetite ore is featured with simple composition, strong magnetism and easy to grind and separate, so the weak magnetic separation process is often used to deal with single magnetic iron ore.
Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
