History. Iron beneficiation has been evident since as early as 800 BC in China with the use of bloomery. A bloomery is the original form of smelting and allowed people to make fires hot enough to melt oxides into a liquid that separates from the iron.
In the electrolytic process, milled high carbon ferrochromium is leached by a mixture of reduced anolyte , a chrome alum mother liquor based on a solution of ammonium sulfate recycled from a later stage in the process, and sulfuric acid. The resultant slurry is cooled, and silica and other undissolved solids are filtered from the solution.

Chromite ore beneficiation machines are allocated according to the specific natures of the chrome ore. The main methods for chrome beneficiation are mainly gravity separation and magnetic separation. And the chrome beneficiation machines are also mainly gravity separators and magnetic separators. So at the beneficiation process, the equipments are quite different from each other because the chrome concentrating methods are different for different chrome ores.
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.
beneficiation of the PGE ores, describing the present status and discussing the new trends. Finally, the third section covers the . extractive metallurgy of the PGEs , again starting with reviewing the existing operations and ending with a presentation of some of the new trends and technologies in that area,
