Ferrochrome is produced using electric submerged Arc furnaces. The closed furnaces are fed raw materials from various sources including chrome ore, coke, char, coal, quartzite and dolomite via the proportioning system for the production of ferrochrome. The valuable portion of the chromite is converted into a metallic phase.
market share is putting jobs at risk. At the same time, exports of unbeneficiated South African chrome ore to China are rising. These exports, which are providing chrome ore feedstock to the South African ferrochrome industry's chief competitor, China, are creating jobs in China and reducing job creation opportunities in South

Ferrochrome (FeCr) is an alloy of chromium and iron containing between 50% and 70% chromium. The Producer od stainless steel & tool steel are the largest consumer of ferrochrome and charge chrome.It is chromium that confers upon stainless steel its remarkable corrosion resistance.
Chromium recovery mainly depends on reducibility of the ore. From the input Cr to the furnace, other than recovered Cr to metal, the balance mainly reports to slag and some to furnace dust. With reference to hard and dense ore, the dust portion is low, but depending on ore reducibility and its size, the Cr2O3 content of slag could increase.
Ferrochromium alloy chromium slag dissemination size is uneven thickness, maximum can up to about 30mm, the minimum is below 1mm, in order to recover as much as possible the ferrochrome, ferrochrome often need to crushing, grinding, recovering jigging process, because the chromium iron alloy high price of coarse-grained and fine-grained, ferrochrome prices are low, so need to early recovery …
The ferrochrome slag production is 1.2 t / t FeCr. It is mainly granulated and the rest is air-cooled. There is an in-house special handling and metal recovery process for the air-cooled slag, where it is made into finished products. In addition to recov-ered ferrochrome, classified slag pr oducts are also made.
Virtually all charge chrome plants now use the crushing/jigging process to recover chrome alloy from both stockpiled and currently produced slag. Studies were carried out at R&D, Tata Steel to develop a flow sheet for the recovery of metal from metal–slag mix generated in its charge chrome (ferrochrome with 50–60% chromium) plant, Bamnipal.
The impact of platinum production from UG2 ore on ferrochrome production (typically 50–52% Cr) to be converted to stainless steel, by the 1980s reserves of Cr/Fe ratios of <2 became the norm.
To improve total ferrochrome recovery while maintaining a high-quality product, alloy recovery plants are utilised to recover the ferrochrome from the slag produced during the charge chrome process. The slag, which has a metallic content of approximately 4 percent, is processed through a series of crushers and broken down to minus 15mm material.
