The process is also known as dressing or benefaction. Gangue is the combined name of the impurities like sand, clay, grit, etc. Gangue needs to be separated because minerals are present in high concentration in its ore. These minerals are extracted by the processes given below: Concentration of ore; Isolation of metal from concentrated ore
The solubility of Al 3 + in concentrated NaOH allows us to isolate aluminum from impure samples of bauxite, an ore of Al 2 O 3. After crushing the ore, we place it in a solution of concentrated NaOH, dissolving the Al 2 O 3 and forming (text{Al(OH)}_4^-). Other oxides in the ore, such as Fe 2 O 3 and SiO 2, remain insoluble.

Most of the microparticle magnetic separations take place in aqueous solutions, whose viscosity plays an important role in the dynamics of the microparticle separation processes. Considering that the magnetic force on the magnetic microparticle decreases faster with its linear dimension (as a cube function of its diameter) than its friction coefficient (as a …
where μ 0 is the permeability of free space and M is the volume magnetization. In the absence of an external magnetic medium, the H-field lines are identical to B-field lines outside a magnet (the stray field) and only differ by a factor μ 0, (B = μ 0 H); but inside they point in a different direction. B is solenoidal (∇⋅B = 0), meaning …

Magnetic separation is a physical separation process that relies on the different magnetic properties of components in a mixture. By applying a magnetic field, magnetic particles are separated from non-magnetic ones based on their magnetic susceptibility and volume, leading to efficient separation of substances.

This process is useful when solid particles do not break down on heating the solution up to the boiling point of the liquid component. On heating, the volatile liquid evaporates, leaving behind the soluble solid as residue. For example, this method can separate a homogeneous mixture of sugar and water. Take the solution of sugar and …
