This …
— The beneficiation studies of Suresh et al. (1981), concludes that low grade chromite ore of 16–25% Cr 2 O 3, of Sitampundi area of India, cannot be upgraded by using tabling and flotation techniques, to meet the metallurgical grade due to the intimate association of iron in the lattice of chromite.
method of transportation is an iron ore slurry pipeline. 4.1.2 Iron Ore Beneficiation Iron ore occurs naturally in a variety of forms, from sand-like iron fines to solid rock masses. Crude ore, or ore mined in the natural state, seldom occurs in a pure state and requires some form of beneficiation. Crude ore is commonly mixed with other ...
— Second priority is given to beneficiation methods for the reduction of iron content (e.g. goethite), which mainly causes settling issues and higher ore consumption in alumina plants. Any reduction in boehmite and organic contents of bauxite are always welcome in a low temperature alumina refinery.
— Magnetic separation is a beneficiation method that uses the magnetic difference between minerals in a non-uniform magnetic field to separate different minerals. Magnetic separation is the most commonly used beneficiation method for ferrous metal ore such as iron ore.
