operational and investment costs The typical cost distribution of a ferrochrome smelter, as predicted by Daavittila et al2, is illustrated in Figure 3 The cost distribution for South African smelters varies slightly; typically chromite ore, reductants, and electricity each account for 30 per cent of the production costs, while Middleburg Ferrochrome (MFC), a company in Samancor Chrome, commissioned a new ferrochrome smelter in March 2009 This is a 60 MW DCarc furnace with a DC power supply for the smelting of Transvaal chromite ore fines With the benefit of 12 years’ experience with this technology while operating a 44 MW DCarc furnace, MFC mitigated all knownLow cost ferroalloy extraction in DCarc T furnace at way of comparison, the size of the smelting units used in ferrochrome production outside Zimbabwe has increased during the past 40 years 6 – 7 times, from 10 MVA to at least 65 MVA 4 Ferrochrome Smelting Challenges The challenges of current ferrochrome production are reduction of investment and operating costsFerrochrome Smelting In Zimbabwe SAIMM
FERROCHROME PRODUCTION FACILITY Noront Resources

Chrome Ores on Ferrochrome Smelting
IGH carbon ferrochrome (HCFeCr) is produced by carbothermic reduction of chrome ore Electric power is generally used to supply the energy required to carry out the heating, melting and reduction reactions The production process is energy intensive, and consumes approximately 3,3003,800 kWh per ton of metal produced The cost of smelter technology will be described on the basis of numerous plants, which are currently under execution or had been commissioned recently SMS Siemag has started an unique longterm research and development project allowing a direct comparison of AC vs DC technology in largeAC AND DC SMELTER TECHNOLOGY FOR FERROUS LOW COST FERROALLOY EXTRACTION IN DCARC FURNACE AT MIDDLEBURG FERROCHROME D Sager1, D Grant2, R Stadler3 and T Schreiter4 1 ABB Switzerland Ltd, Austrasse, CH5300 Turgi, Switzerland; 2 Middleburg Ferrochrome (a company in Samancor Chrome), Private Bag X, Middleburg 1050; LOW COST FERROALLOY EXTRACTION IN DCARC

LOW COST FERROALLOY EXTRACTION IN DCARC
Chrome smelter in March 2009 This is a 60 MW DCarc furnace with a DC power supply for the smelting of Transvaal chromite ore fines With the benefit of 12 years experience with this technology while operating a 44 MW DCarc furnace, MFC mitigated all known challenges and considered up 3,3003,800 kWh per ton of metal produced The cost of electricity counts for about 3540% of total production cost Due to the shortage of power supply in South Africa, the cost of electricity has more than doubled since 2008, and a plan has been tabled to increase the electricity price by 16% every year from 2013 to 2018Chrome Ores on Ferrochrome Smelting Construction of the smelter is expected to begin in 2025 over an estimated threeyear period with an estimated cost of about US$1Bn The timeline of the ferrochrome plant, however, will be determined by the development of road Chromium: A North American ferrochrome smelter by
