Roasting in air at temperatures between 500 and 650°C converts MoS 2 concentrate into roasted molybdenite (MoO 3) concentrate (also known as technical mo oxide, or tech oxide) by the chemical reactions: 2MoS 2 + 7O 2,Technology of Molybdenum Ferroalloys - ScienceDirect,01/01/2013· Additionally, roasted concentrate contains 14% to 16% CaO, <3% FeO, <1.5% MgO, <0.7% Al 2 O 3, and 0.15% to 0.5% W. About one tenth of all molybdenum in this concentrate is present as MoO 2, and the rest is present in the form of MoO 3. 12.4.

Studies on the processing of a low grade molybdenite,

01/01/1988· Figure 3 is a flow diagram showing the sequential steps in the extraction of molybdenum from low grade molybdenite by the lime roast process. The flow sheet also includes the carbon-adsorption route for the preparation of high purity MoO3 product. CONCLUSIONS The process described above has demonstrated the feasibility of solubilising molybdenum values of a low grade molybdenite1 J.W. Blossom, Molybdenum, from Minerals Yearbook Volume,,2. Generalized Process Flow Diagram Molybdenum Metal and Ammonium Molybdate Molybdenum metal and ammonium molybdate are made by roasting concentrated molybdenite ore, as shown in Exhibit 2.

The solutions and supernatant liquids contain the molybdate ion and, in addition at lower pHs, protonated molybdate. At biological concentrations and pH the only molybdenum species produced from the molybdenum substances studied is the molybdate, [MoO 4] 2-, ion. Read across from sodium molybdate is therefore justified.

The use of fluidized beds for roasting fine concentrate is obviously attractive. If a gas is passed upward through a bed of solid particles of small and preferably regular size in the range 2–0.02mm diameter, the behavior of the bed will depend upon the velocity of the gas. At very low flow rates the gas permeates through the bed withoutRotary Dryer for Roasting Molybdenum Concentrate,,This paper mainly discusses the process flow of oxidizing roast molybdenum concentrate by rotary dryer,roasting temperature and cleaning method of gas at dryer tail and how to determine residence time for molybdenum concentrate in the dryer and internal dimension of the dryer.Short-flow preparation of pure MoO3 from CaCO3-added,,As a result, over 94% of Mo is separated as pure MoO3 when MoS2 concentrate pellets are added with 60% CaCO3 and roasted at 775 °C for 2 h in the atmosphere containing 25% SO2.
