Title: Method of carbon free Mo briquette
Inventor: SONG JE JUNG
IPC: C22C1/05
Filed: 2019-05-08
Abstract: In a valuable metal recovery process, due to economic, environmental and technical limitations, most of the spent catalysts generated in Korea are being leaked to foreign countries such as China. This is not only a loss of valuable domestic metals, but may cause disputes between countries in terms of future environmental waste transactions, so national management is required, and there is an urgent need to develop and commercialize technologies of rematerializing valuable metals from waste resources that can cope with the same. As raw material prices increase, the price of subsidiary materials for the production of alloy steels is gradually increasing, and a price increase of Fe-Mo used in the production of alloy steels containing molybdenum is very high, so that reduction in production cost of alloy steel is required. A producing process of ferromolybdenum is complex, and a reducing agent such as aluminum and silicon are used. Prices of the reducing agents are expensive, thereby causing an increase in manufacturing cost. A binder to be mixed when producing special steel has low specific gravity, thereby causing environmental problems, etc. by being scattered into the air during a process of being inputted. Due to such problems, ferromolybdenum is being sold at a higher price than molybdenum oxide. Therefore, the price competitiveness as a ferromolybdenum substitute can be obtained by manufacturing a product with a standard similar to that of ferromolybdenum through the present invention. The present invention relates to a technology to manufacture a molybdenum trioxide briquette by adjusting amounts of inorganic binders to be added per type, and then mixing the binders with molybdenum trioxide inside a blender.
