chromium processing - chromium processing - The metal and its alloys: By far the greatest use of chromium is as a ferrochromium alloying agent in steel manufacture. Pure chromium is added to nonferrous alloys and is also applied as a corrosion-resistant surfacing for other metals. Chromium surfaces are produced on other metals by electroplating and chromizing.

ORE TRACKING: Mining equipment implemented for ore extraction is optimal for selective mining. Material from the pit is transported to various stockpile destinations. These include high-grade (>13% Zn), medium-grade (9 - 13% Zn), low-grade (4 - 9% Zn) and marginal (1 - 4% Zn) ore stockpiles. Limestone (Ca >28%) from the pit is mined for plant acid

Ferrochrome (>62%Cr) and charge chrome (45–52%Cr) production using the submerged arc furnace (SAF) is an established practice in India. As the majority of Cr rich Indian chromite ore are friable in nature and available in fine form, utilisation of chromite fines for production of superior quality ferrochrome is essential.

The benchmark is negotiated every quarter by a leading South African ferro-chrome producer and a major European stainless steel mill. The settlement is announced by Merafe Resources, which operates a chrome joint venture with trader-miner Glencore in South Africa. The benchmark is a forward-looking price for the coming quarter.

Excess lumpy chrome ore mined at Stellite is exported directly to China. Stellite is located on the western limb of the Bushveld complex in South Africa, where 70% of the world's chrome resources are located and 40% of chrome production is sourced. The mine has a chromite resource of 32Mt comprising of four seams, namely the LG6, MG1, MG2 and ...

Chrome plating is used to provide a very high degree of hardness on the surface of a metal to enhance wear resistance, reduce friction, provide anti-galling properties, and, in some cases, improve corrosion resistance. Chrome plating is an electrolytic process that can be applied to regular steel, stainless steel, aluminum, and other materials.

World high carbon ferrochrome production, charge chrome and HCFeCr, was 6.0 million tonnes in 2005. The production increased by 2.8 per cent from the year 2004. Almost all ferrochrome is produced in submerged electric arc furnaces. The raw material in the production of ferrochrome is chromite, which is chrome and iron oxides containing mineral.
