Industrially, the process is done either during dephosphorization or after dephosphorization and desulfurization. 7.4.3 Chromium. Chromium is present in ferronickel arising from smelting furnaces that operate with high contents of carbon in the feed. The chromium content in this type of ferronickel can be up to 1.7% (Bergman, 2003).It is removed during carbon oxidation with little loss of nickel.

Ferronickel an overview ScienceDirect Topics

Ferronickel smelters are often based on one smelting furnace, which can typically produce about 50 000 tonnes of nickel in ferronickel per year. This is the minimum economic size of a ferronickel operation. Additional production requires a second furnace, together with ancillary equipment, requiring considerably more capital investment.
