air density separator for iron ore beneficiation

Dastur and Company | Engineering Design Services

In medium and low grade ores these fines are used in agglomeration that increases the cost of ironmaking due to the alumina content [1]. Therefore iron ore beneficiation in the fines range calls for new processes. In this regard, a novel method was devised at CSIR-NML in collaboration with M N Dastur & Co along the lines of dry ore processing.

Dry separation of particulate iron ore using density ...

Abstract A gas–solid fluidized bed has been used to separate particulate iron ore (+250–500 μm in size) by segregating the particles by density. The ore particles were put into a cylindrical column of inner diameter of 100 mm and bed height of 50 mm, and were fluidized at a given air velocity u 0 / u mf = 1.2–3.2 for 10 min. u 0 and u mf are the superficial air velocity and the minimum ...

Beneficiation - Wikipedia

For sulfide ores, a different process is taken for beneficiation. The ore needs to have the sulfur removed before smelting can begin. Roasting is the primary method of separating, where wood was placed on heaps of ore and set on fire to help with oxidation. 2 Cu 2 S + 3 O 2 → 2 Cu 2 O + 2 SO 2

A dry density-based fluidized bed separator was used to beneficiate coarse particulate iron ore. The atomized iron powder and zircon sand, with specific size fractions of 150–75 and 250–150 μm, were mixed in certain proportion to form a binary dense media.The results indicated that the binary dense media efficiently formed stable fluidization within the fluidized bed for subsequent ...
