Title:
A METHOD OF MANUFACTURING V PRODUCT UTILIZING FLUIDIZATION TECHNOLOGY
Document Type and Number:
WIPO Patent Application WO/2009/071006
Kind Code:
A1
Abstract:
A method of manufacturing V product utilizing fluidization technology and fluidization
device comprises: calcining V slag with high Ca in a fluidized furnace, in which
the weight ratio of CaO to V2O5 is 0.5-1.4, the average temperature
in the fluidized furnace is 850-950?, and the average residence time of the V slag
in the furnace is 30-150 minutes; leaching calcined product in sulphuric acid;
and producing V product from leach solution. Compared with methods which use
rotary kiln or multi-chamber furnace as calcining devices, the method has high
production efficiency, low energy consumption and high productivity, and it
is easy to realize large-scale manufacture.
