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.

Extraction of vanadium from athabasca tar sands fly ash

Although the recovery of vanadium from petroleum ash is a well established commercial practice, it is shown in the present work that such processes are not suitable for recovery of vanadium from the GCOS fly ash. The fact that the GCOS fly ash behaves so differently when compared to other petroleum fly ash is attributed to its high silicon and
