Description
Technical field
The invention belongs to chemical material fields, specifically, the present invention relates to a kind of metallurgical materials and sodium carbonate activation to roast
Firing method.
Background technique
Molybdenum is that a kind of less refractory metal element is distributed in the earth's crust, and the compound of metal molybdenum, molybdenum alloy and molybdenum is extensive
Many fields applied to modern technologies in, with the development of the industries such as the energy, electronics, aviation, military affairs and steel, molybdenum ore disappears
Consumption is increasing.Abundance of the molybdenum element in the earth's crust is 3 × 10-4, with the increase of yield, the pressure of resource exhaustion is more next
It is bigger.Currently, for low-grade and Mo resource secondary use, it is more and more.But in these raw materials, impurity content compared with
Height, especially P, Si, V equal size is higher, affects the quality of molybdenum product.
Vanadium, molybdenum property are more close, are the common accompanying elements of molybdenum in vanadium in mineral, therefore, remove vanadium the most in impurity
It is difficult.In the nickel-molybdenum ore on the ground such as Guizhou, the Hunan in China, content of vanadium is relatively high.In some dead catalyst of petroleum containing molybdenum
Contain a large amount of vanadium.Presentation quality and service performance can be seriously affected containing V in molybdenum product.It is relatively effective at present to remove vanadium method packet
Include resins exchange column adsorption method, solvent extraction etc..But exist and remove vanadium low efficiency, process flow is long, and higher cost lacks
It falls into.
Therefore, there is an urgent need in the art to develop the process that can effectively remove vanadium.
