  • Ferrochrome (FeCr) – Mineral-Loy

    Ferrochrome (FeCr) is an alloy of chromium and iron, generally containing 48 to 70% chromium by weight. It is produced in an electric arc furnace by the reduction of chromite ore. South Africa has the largest reserves of chromite ore and is also the world's largest producer of Ferrochrome with most production being exported to China.


  • environmental affairs

    When enough smelted ferrochrome has accumulated in the hearth of the furnace, the tap hole is drilled open and a stream of molten metal and slag flows down a trough into a chill or ladle. The ferrochrome solidifies in large castings, while the slag is separated and stockpiled for further processing.

  • Ferrochrome slag aggregate: physical-chemical characteristics ...

    Ferrochrome slag aggregates have excellent physical-mechanical characteristics that conform to international specifications for use in road base construction. The slag can be classified as non-hazardous solid waste. However, in acidic environments, some toxic elements may leach from the slag and pollute the environment.


  • Impact of air granulation on the ferrochrome value chain in ...

    South African ferrochrome producers typically operate single tap-hole furnaces with alloy and slag separation occurring post-taphole by means of a skimmer block. Both streams are then cast directly onto a prepared surface, or in some cases a layer-casting process is employed using hot metal ladles.


  • DC ARC FURNACES – PAST, PRESENT, AND FUTURE - Mintek

    Mintek and Middelburg Steel & Alloys (now part of Samancor Chrome) conducted smelting trials on Tetronics' pilot transferred-arc plasma furnaces in the UK in 1979/80. These trials showed successful metallurgy, but this type of furnace was seen as difficult to scale up to the very large furnaces that were required for the ferro-alloys industry.



  • SOME ASPECTS OF THE PRODUCTION OF FERROCHROME ALLOYS ... - Mintek

    The main features of this mode are the electrical resistivity of the slag and the slag liquidus temperature that are strictly selected to operate the process comfortably; these two parameters also impose some limitations to the smelting process in terms of operating temperature.


  • Research on the use of Ferro-Chrome slag in civil engineering ...

    Internationally, e.g. South Africa, India, Norway, Turkey, East Europe, China, Sweden and USA, ferrochrome slag is used commercially in the road and construction Industries. This material is being used for road construction, as aggregates in concrete industry, brick manufacturing, and in pavement construction as engineering fill and has ...

    The latter slag type is presented in Figure 5 and Figure 6. Fluxing to produce the required slag composition was carried out using either silica or a combination of silica and lime (in the form of burnt lime or limestone). The resulting ternary slag contained in mass percent about 30-40% MgO, 30-40% Al2O3 and 20-30% SiO2. In the quaternary slag ...

  • Effect of Chrome Ore Quality on Ferrochrome Production Efficiency

    The mining operation that commenced in 1963, is situated on the Aseminoon Mining Complex. Up to 1995 the output was exported mainly to countries including Japan and China. Since then due to commissioning of its ferroalloy plant, besides the export of ore, high carbon ferrochromium has been produced.
