extraction of non magnetic iron ore

The invention discloses a simple method for extracting pentlandite monominerals. The method is characterized in that copper-nickel sulphide ore is used as a raw material, and a magnetic field of which the strength gradually increases is applied to the copper-nickel sulphide ore through a permanent magnet, so as to achieve stage-by-stage magnetic separation of the copper-nickel sulphide ore.

Digestion of Alumina from Non Magnetic Material Obtained

Recovery of iron from iron-rich diasporic bauxite ore via reductive roasting followed by magnetic separation has been explored recently. However, the efficiency of alumina extraction in the non-magnetic materials is absent. In this paper, a further study on the digestion of alumina by the Bayer process from non-magnetic material obtained after magnetic separation of reduced iron-rich …

Characterisation and magnetic concentration of an iron ore

Jan 01, 2019 Based on the ore characteristics (e.g. particle size, mineralogy and grade), gravity concentration (jig and Humphreys spiral), magnetic separation (low and high-field) and inverse cationic flotation (especially applied to pellet feeds) are used [3], [4]. It is estimated that for each tonne of beneficiated iron ore, 400 kg of tailings are produced.

Extraction of Iron Iron Mining Iron Ore Processing

Hematite is easier to floated than magnetic, which could be separated by positive flotation. As the density of iron ore is much higher than that of gangue mineral, gangue mineral is more likely to attach to the foam than iron ore. Therefore, for the extraction of iron ore, reverse flotation is more advantageous than positive flotation.
