Raw materials like iron ore, coke, and limestone are used in ferroalloy production. The electric arc furnace is the primary equipment for producing ferroalloys. Smelting involves heating the raw materials to high temperatures to extract the desired elements. The process generates significant amounts of slag, a byproduct that must be managed.

World Chrome Ore Reserves. The World's largest chrome ore reserve base (6403 Mt) is located in the Southern African region and is associated with the Bushveld Complex and the Great DWorld Chrome Ore Reserves, Zimbabwe.. Perched at a majestic 5,550 Mt, South Africa proudly claims 72.4% of the planet's chrome ore riches. However, there's an interesting twist.
The increasing and unrestricted exports of chrome ore from South Africa is also contributing to displacement of ferrochrome volumes from South Africa. Key statistics for 2019 Global ferrochrome production increased from 13.6 million tonnes in 2018 to approximately 14 million tonnes in 2019.

Low carbon ferrochrome (LC FeCr) is a ferroalloy with low carbon content, widely used in the production of stainless steel and other special steels. As an important metallurgical material, low carbon ferrochrome not only enhances the corrosion resistance and strength of steel but also excels in energy conservation and emission reduction. This article will discuss in …
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 1.2–1.5 tons of slag containing approximately 8–12% of chromium oxide is generated per ton of hot metal (Jena and …
Ferrochrome slag (FCS) is a by-product of ferrochrome industries and is produced during the extraction of ferrochrome from chromite ore. The chemical composition of FCS comprises of 27–33% SiO 2, 15–25% Al 2 O 3, 20–35% MgO, and 10–15% iron …
Ferro-chrome alloy is produced from lump chromite ores in the submerged arc furnace (SAF). Majority of the lump ore is very lean (~30% Cr) in nature. Production of good quality ferro-chrome requires high-grade chromite ores; but these are fragile and tend to form fines during handling. Therefore agglomeration of these fines is needed before charging in SAF.
Ferrochrome slag (FCS) and ferrochrome ash (FCA) are by-products generated during the production of ferrochrome alloy in the ferrochrome industry.
The primary raw materials used in ferrochrome production are chromite ore, iron ore, and coke. Chromite ore, containing chromium in the form of chromite minerals (FeCr 2 O 4), is the key ingredient. Iron ore, typically in the form of iron oxide, provides the iron component, while coke, a form of carbon derived from coal, serves as a reducing agent.
