  • Chrome Smelting Production Costs

    Chrome Smelting Production Costs. Lumpy chrome ores from six different locations of the Bushveld Igneous Complex are used. Quartzite is added as flux, and coke is used as reductant. The chemical composition of quartzite and coke are listed in Table II. Based on the production of ferrochrome in South Africa, the following conditions are used as major smelting parameters: Send Message Chat

    electricity counts for about 35-40% 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 2018. South Africa, with 80% of world chrome or reserves, is one of the major producers of ferrochrome, and its production accounts

  • SOME ASPECTS OF THE PRODUCTION OF FERROCHROME

    High-carbon and charge chrome alloys are generally produced in the conventional smelting process by carbothermic reduction of ferrochrome ores using AC submerged-arc and DC open-arc electric furnaces. In AC submerged-arc furnaces, the energy to the furnace is predominantly supplied in a resistive heating mode. The main features of this mode are the electrical resistivity of the slag and the

    Average chrome content in stainless steel is approx. 18%. It is also used to add chromium to In the process of smelting, huge amounts of electricity are consumed, making production very expensive in countries where power costs are high. Tapping of the material from the furnace takes place intermittently. When enough smelted ferrochrome has accumulated in the furnace hearth, the tap hole is

  • smelting Definition & Facts Britannica

    Smelting, process by which a metal is obtained, either as the element or as a simple compound, from its ore by heating beyond the melting point, ordinarily in the presence of oxidizing agents, such as air, or reducing agents, such as coke. The first metal to be smelted in the ancient Middle East was probably copper (by 5000 bce), followed by tin, lead, and silver. To achieve the high

    the latter process, even more UG2 can be used due to the higher chrome recovery of the process. The pellets are fed in various forms, including prereduced, sintered/pre-oxidized, cold or preheated, to a SAF. In terms of DC-arc furnace smelting, the process is inherently suitable for the use of UG2 ore. The process is relatively insensitive to
