Özet

Molybdenum is a refractory metal that has melting point at ~2610 °C. It has high modulus of elasticity even at elevated temperatures. Almost 80% of molybdenum is used as alloying element for ferromolybdenum. When added to steel, molybdenum increases strength hardenability, toughness, elevated temperature strength and corrosion resistance. Molybdenum metal is produced from its sulphide ore through oxidizing roasting of molybdenite to produce molybdenum trioxide and then purification of molybdenum trioxide and hydrogen reduction of molybdenum trioxide. In this study molybdenite (MoS2) is roasted in both chamber type furnace and rotary kiln under different conditions such as different temperatures and air atmospheres. Samples were taken off during the roasting process to analyze the sulphur content. After roasting experiments a kinetic study was carried out. Activation energies were calculated for both conditions and compared to each other. The raw materials and the products were characterized by using XRD and AAS.
