The balance of the energy requirement in the KWG process developed at XPS is provided by natural gas, which has a higher calorific value than coal, Consumption is very conservatively estimated at 80% of that of the overall Premus process, an estimated 136 kg gas per ton FeCr. This is based on: The lower operating temperature of the KWG process
India – FeCr industry characteristics (often need to purchase coal or oil to generate it) • Low labour costs, but mining restrictions becoming strict • Average production costs quite high, but integrated players competitive, greatly assisted by weak rupee in 2013
Keywords: Pyrometallurgy, furnace, Xstrata, ferrochromium, Premus Technology Abstract – The presentation will give a basic overview of Xstrata Alloys. Included will be a brief history of the Alloys division as well as of each plant within the division. The Xstrata chrome plants utilise a wide variety of production processes,
Oct 20, 2010· One of the world's biggest producers of ferrochrome, the company revealed in a statement here that it had approved the second phase of its Lion ferrochrome complex. "The use of our energy-efficient Premus technology for the expansion project will expand Xstrata's cost leadership in a global environment of escalating energy costs," said ...
The expansion will utilise Xstrata's proprietary energy-efficient Premus technology, and will reduce the overall cost of the Venture's total ferrochrome production by around 6%. Xstrata's Premus technology consumes approximately a third less electricity than other available smelting technologies – an industry leading average of between ...
• World-leading technology and processes: • 22 furnaces spread across five smelting facilities in South Africa, with a capacity of 2.34 million tonnes per annum. Three technologies are employed; conventional, Outokumpu and Premus. • Premus technology is the most sophisticated ferrochrome production technology
Ferrochrome. Most of the world's ferrochrome is used in the production of corrosion resistant steel, more specifically stainless steel. Manganese alloys. Most of the world's manganese is used in carbon steel production. Ferrovanadium. Vanadium alloys are used to strengthen specialty steels for use in niche and high-end applications. It is also ...

• Production costs very varied between plants – driven by technology and capacity utilisation • Depressed production and low capacity utilisation in 2012 and 2013 due to poor market fundamentals – this has impacted on unit costs South Africa – FeCr industry characteristics
Apr 01, 2004· Free Online Library: New S African venture to lead world's ferrochrome output: a proposed joint venture will make a new South African entity the largest ferrochrome producer in the world. The demand for ferrocrome, which is used in the manufacture of stainless steel, is bound to rise as the demand for steel, especially in China, increases.
Oct 04, 2017· Sustainable wastewater technologies minimize mining's environmental footprint. Mining for some minerals, including coal, has been diminishing due to increased financial, social, and environmental pressures, both in the United States and abroad.
Due to the fact that Premus is one of the most tech nologically advanced and comp etitive processes used today in the production of ferrochrome it was the process selected for Xstrata's new ferrochrome facility, Project Lion, that is due to be commissioned in the third quarter of 2006 in the Steelpoort Valley in Mpumulanga, South Africa. 1.
