Chromite tailings are generated from chrome ore beneficiation plants, containing substantial quantities of ultrafine particles. Generally these ultrafine particles of chromite cannot be treated effectively using conventional beneficiation methods, because of limitations in particles size being treated by these processes.

Beneficiation is followed by processing activities such as smelting and refining. The beneficiation process begins with milling, which is followed by flotation for further beneficiation. At the first stage, extracted ores undergo the milling operation to produce uniformly sized particles for crushing, grinding, wet or dry concentration.
Grinding is a size reduction process that involves breaking down the ore into smaller particles to increase its surface area for subsequent beneficiation. The objective of grinding is to liberate the valuable iron-bearing minerals from the gangue and prepare the ore for efficient separation.

An important issue in the beneficiation of bauxite is the fine dispersion of iron oxides, alumina, kaolinitic clays and other minerals. However, in many−but certainly not all−deposits, the detrimental kaolinite is present in a large proportion as loose accumulations of clay-sized (<4 µm) particles, not intergrown with gibbsite.
The importance of ore sorting in improving economics of marginal deposits is increasing, being realized by the mining industry (Lessard et al. 2014; Foggiatto et al. 2014). At present, majority of automated ore sorters, outside of the diamond industry, are color or conductivity sorters (Bartram and Kowalczyk 2009). This is a significant ...
