Extraction of vanadium and potassium compounds from the spent vanadium catalyst from the metallurgical plant

Mazurek K.

Polish Journal of Chemical Technology

2012

Vol. 14, nr 2

49-53

A spent vanadium catalyst, from the plant of metallurgical type, was leached in a sulfuric acid solution to recover vanadium and potassium compounds. The effect of time, temperature, concentration of acid, catalyst particle size and phase ratio was studied. Additionally the concentration of iron, copper, zinc, arsenic and lead compounds was determined. The flow sheet for the proposed process of spent vanadium catalyst leaching is presented.
