| FerroMolybdenum Production at Bear Metallurgical Company Michael Hart1; 1BEAR METALLURGICAL COMPANY, Butler, United States; PAPER: 407/Ferro-alloys/Regular (Oral) SCHEDULED: 15:55/Fri. 25 Oct. 2019/Zeus (55/Mezz. F) 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 |
