Paper Id: 407
[Abstract] The production of ferromolybdenum at Bear Metallurgical is carried out by reducing the Molybdenum Trioxide (MoO3), contained in primary or recycled materials using FeSi (and sometimes aluminum) as a main reductant, iron or iron oxide as alloy formation agents and lime as slag conditioner in a so-called silicothermic reaction which provides the necessary heat for the process and avoids the need for extra sources of energy. In this paper, the production flowsheet from the receipt of the primary materials, to batching, blending, smelting and then crashing, sampling, product specifications and quality testing are described along with the characteristics of this special silicothermic process related to molybdenum reaction, its speed energy and temperature, furnace separation, process control, efficiency as well as and its special reactor furnace

Paper Id: 403
[Abstract] The production of ferrovanadium at Bear Metallurgical is carried out by reducing the Vanadium Pentoxide (V2O5) contained in ores or in recycled materials using aluminum as a reductant and iron as alloy formation agent in a so called violent Aluminothermic reaction which is properly controlled during the process. Although the process is straightforward, the nuances in the production make it a complex one. In this paper the production flowsheet from the feed preparation to blending, from smelting to product specifications and quality testing are described along with the characteristics of this special aluminothermic process related to its speed and temperature, its control and efficiency as well as and its special reactor furnace.
