· The extraction of vanadium from high calcium vanadium slag was attempted by direct roasting and soda leaching. The oxidation process of the vanadium slag at different temperatures was investigated by Xray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS). The effects of roasting temperature, roasting time, Na2CO3 concentration, .

Ladles used aboard repair ships are of two basic types. The lippouring ladle is shown in figure 186 and the teapot, or bottompouring ladle, is shown in figure 187. Crucibles, such as shown in figure 188, are a type of lippouring ladle. Teapot crucibles are shown in figure 189. Ladle bowls are usually of welded or pressed steel construction.

A duplex BOF process in the steelmaking shop yields a vanadium rich slag that can be converted into V2O5 via hydrometallurgical processing. Coal in parts of China and the USA contains vanadium. During the refining or burning of these energy sources a vanadium bearing ash, slag, spent alyst or residue is generated which can be processed for vanadium recovery.
