Ferrochrome. High grade anthracite, specially processed by G&W Mineral Resources is used as a carbon content enhancer in the production process of ferrochrome. Pelbond, a Bentonite product, and Mozambique Bentonite are used as binding agents for ore pelletizing applications.
Aug 25, 2014· Low carbon ferrochrome is exactly the same alloy but it contains very less amount of carbon. To lower carbon content a completely different process is used to produce it. Instead of carbothermic reduction, oxides are reduced with silicothermic reduction. The most popular process is the Perrin process to produce low carbon ferrochrome.
The physical and process properties of ferrochrome powder produced by grinding of lump high-carbon ferrochrome FKh800 are examined. It is found that the ferrochrome is pulverized sufficiently well, and its physical and process properties allow its use to make wear-resistant powder materials.
A method for improved process for production of High Carbon Ferrochrome (HCFeCr) and Charge Chrome comprising: blending dried chrome concentrate and chromite fines in all possible proportions to form raw feed ore; subjecting the raw feed ore to the step of mixing hydrated lime, molasses and bentonite as the binders to the said mixture to form briquetting mixture feed; forming briquettes from ...
The conventional process for producing high carbon ferrochromium by smelting chromite ore in a submerged arc furnace is reviewed and its limitations highlighted with regard to (a) product quality through impurity removal, and (b) high power consumption for a given raw materials supply. The trends towards (i) utilization of medium grade ore fines by

Ferrochrome can be of two types based on the amount of carbon it has; low carbon Ferrochrome and high carbon Ferrochrome. Most of the Ferrochrome in the world market comes now from places like South Africa, Kazakhstan, India and Turkey. In these counties, the substance is produced in specialized Ferrochrome plants.
The previous chapter focused on the use of high-purity chromium metal for high-performance alloys in jet-engine applications. Technical emphasis in this chapter focuses on the two main variations of the electrolytic process that have traditionally produced high-purity chromium metal: the trivalent chrome-alum electrolyte method and the chromic-acid electrolyte method.
The efficiency of the ferrochrome process is very much driven by the type and pre-conditioning of the feed materials. Processing fine feed material requires high operating temperatures and consequently high power input to ensure the even flow of material to prevent sintering or hanging of furnace charge.
Production of low-carbon stainless steels by first producing a ferrochrome alloy with less than 2 percent carbon by vacuum reduction and simple melting, and then processing this alloy with scrap in the AOD should result in an energy savings equal to that required for decarburization of high-carbon ferrochrome to the carbon content of the vacuum ...

High carbon ferrochrome is primarily used in the production of stainless steel. More than 90% of high carbon ferrochrome is used in the production of stainless steel (International Chromium Development Association [ICDA], 2011). The majority of the balance is used in the manufacturing of special steels (including high chromium steels). 9.2.
China is the world's top consumer of chromium, as well as the top stainless steel producer. However, it has no chromium production at all. It also has very few choices in where to get it — the ...
