vanadium separation from fly ash

Extraction and separation of vanadium and nickel from fly

Sep 01, 2011· Highlights Large amounts of fly ash are produced as a result of burning diesel fuel in power stations. Ni is selectively eluted from the FA using NH 3 solution and was precipitated as NiS. V is extracted from Ni-free-FA by Na 2 CO 3 solution and precipitated by NH 4 Cl. The proposed method herein showed a high recovery (97%) for both metals.
