A direct reduction process for the production of ferrochrome from chromite ore or concentrate is disclosed. According to the present invention, calcium chloride CaCl2 is added as a catalyst to accelerate the solid reduction and enhance the particle growth of the metallic phase i.e. ferrochrome during reduction. The reduction of chromite ore or concentrate takes place at much lower ...
The structural and electromagnetic properties of high-carbon ferrochrome powders HCFCP obtained at different cooling rates were respectively investigated by means of optical microscope, X-ray diffractometer, electron probe as well as the vector network analyzer in the frequency range of 1-18 GHz. The results show that the cell structure of main phase, Cr,Fe SUB 7 SUB C SUB 3 SUB ...

ferrochrome slags Figure 3, small metallic particles 20-40 m are present in a matrix of Ca-silicates and spinel phases 10 m that contain Cr. ... magnetic, electrostatic and enhanced gravity separation. Comminution has a high energy demand, with associated high costs. Microwaves
The first was a 48MW circular furnace used for the production of ferrochrome, whilst the second was a 68MW 6-in-line rectangular furnace used for the smelting of copper-nickel concentrate. The purpose ... magnetic flux density, J electric current density and the electric charge density.
May 15, 2018 In this present study, ferrochrome was derived from Indonesian chromite sand with low-grade CrFe ratio. In order to improve the ratio, beneficiation process such as pre-magnetic separation and reduction process at 1000 C for 60 minutes was required.
Sep 25, 2020 Magnetic Separation. Because the chromite has a weak magnetism, we can use the strong magnetic separator for chrome extraction. There are mainly the following two cases one is in the weak magnetic field, remove the ore in the strong magnetic separation of minerals main magnetite, improve the ratio of ferrochrome.
The generator connected to the turbine produces electricity by turning a copper circuit inside of a magnetic field, and the turning of the copper inside the magnetic field generates electricity. The electricity generated in the circuit is then fed to the electrical substation, which sends the power to the ferrochrome production plant or the ...
Oct 08, 2019 A method and system for recovering a high yield of low carbon ferrochrome from chromite and low carbon ferrochrome produced by the method. A stoichiometric mixture of feed materials including scrap aluminum granules, lime, silica sand, and chromite ore are provided into a plasma arc furnace. The scrap aluminum granules are produced from used aluminum beverage
The ferrochrome is produced by electric arc melting of chromite, an iron magnesium chromium oxide and the most important chromium ore. 3. Chromite is used to produce Chrome brick,,Chrome magnesium brick and other special refractories in fireproofing.
