Low carbon ferrochrome contains less than % carbon making it suitable for applications requiring minimized carbon levels It finds common use in the production of low carbon and ultra low carbon stainless steels Charge Chrome Charge chrome refers to a high grade ferrochrome used in the production of stainless steel and specialty alloys
Hence ferrochrome slag is thought to be a useful raw material for production of high temperature insulation bricks construction work using geopolymer made from chromium slag etc Therefore R&D scientists are trying to find suitable uses for other applications In this chapter the fundamentals of ferrochrome slag chemistry are discussed
In support of these and other research projects this Center has analyzed a large number of samples of chromite ore ferrochrome ferrochrome slag and solids and solutions from chromium recovery investigations The large number of samples processed has promoted refinement of the analytical methods used so that reliability of the results is
Ferrochrome slag is a by product of the production of ferro chrome alloy an essential component in stainless steel The conventional process of ferrochrome making involves the carbothermic reduction of chromite ore where around tons of slag containing approximately 8 12% of chromium oxide is generated per ton of hot metal Jena and
In ferrochrome manufacturing process the slag is a reactive medium where most of the reduction reaction takes place Ferrochrome FeCr slag is found to consist of mainly silica alumina and magnesia with significant amounts of chromium and iron oxides in the form of Partially Altered Chromite PAC and entrained ferrochrome alloy [4] At smelting condition
Ferrochrome slag is a common industrial solid waste produced during the smelting of chromite in submerged arc furnaces [8] In the current production process for every 1 ton of ferrochrome alloy manufactured approximately tons to tons of chromite are consumed resulting in the production of 1 ton to tons of ferrochrome slag [9] [10]
Hence ferrochrome slag is thought to be a useful raw material for production of high temperature insulation bricks construction work using geopolymer made from chromium slag etc Therefore R&D scientists are trying to find suitable uses for other applications In this chapter the fundamentals of ferrochrome slag chemistry are discussed
Ferrochrome slag is a waste material obtained from the manufacturing of high carbon ferrochromium alloy This slag is formed as a liquid at 1700 oC and its main components are O3 and MgO Additionally it consists of chrome The slag was found to be particularly suitable for high strength concrete M 55 and higher The mechanical
Purpose Most developing countries simply dump ferrochrome slag as waste which occupies huge areas of useful land The purpose of this study is to underscore the significance of reusing ferrochrome slag as a sustainable and eco friendly road aggregate material with the added benefits of preventing possible environmental pollution and promoting
A key learning from this study indicates that ferrochrome slag is a potentially suitable alternative to natural aggregate for road construction and concrete in South Africa and it has become a preferred alternative to natural aggregate in many other countries The benefit of recycling waste such as ferrochrome slag can be summarised as
Based on study it was recommended that water cooled Ferrochrome slag can be used as replacement of natural fine aggregate up to 60% by weight along with 100 % with natural coarse aggregates for
Ferrochrome slag is found to be suitable as construction material due to its excellent technical and material properties but its use is limited due to the environmental concern of cooled slag is used as a partial substitution of coarse aggregate in concrete and water cooled granulated slag is used as a partial
use of ferrochrome slag in various civil engineering applications such as road construction and cement and concrete industries 2 Ferrochrome FeCr Slag Ferrochrome FeCr slag is by product from the production of Ferrochrome an essential component in stainless steel industry [2] An amount of to ton
The concrete product with ferrochrome slag as coarse and fine aggregate showed excellent results with respect to compressive strength and were found to be suitable for general purpose concrete work
The high carbon ferrochrome slag is generally agglomerate and the low carbon ferrochrome slag usually consists of small particles In 2022 14 62 million tons of carbon ferrochrome slags were

Metso and Ferro Alloys Corporation Limited FACOR part of Vedanta have agreed on the design and delivery of a ferrochrome plant for FACOR s expansion project in Bhadrak Odisha in India The contract value of approximately EUR 80 million is booked in the Minerals segment s fourth quarter 2023 order Metso s scope of delivery includes the
After a rough first large chromite residue jaw crusher broken into small pieces pieces of fine chromite slag into jaw crusher for fine crushing so that the final particle size control in less than 30mm then enter the silo hopper bottom Let electromagnetic vibrating feeder the crushed ferrochromium slag evenly fed into AM30 jig jigging
experiences from other industries such as the ferrochrome industry in Finland and the European steel industry The outcome from this was the development of a roadmap which proposes how the utilization of ferrochrome slag might be increased Innoationv platforms are mooted as a suitable approach through which to apply the proposed roadmap in
Ferrochrome FeCr slag is a by product from the production of ferrochrome an essential component in the stainless steel industry Between and t of slag is produced for each ton of FeCr
However the water absorption rate is relatively high due to the porous nature of the slag 2 Ferrochrome FeCr Slag Ferrochrome FeCr slag is by product from the production of Ferrochrome an essential component in stainless steel industry [2] An amount of to ton of slag is produced for each ton of FeCr [3]
