It did not contain gold, but its presence in the solutions prevented zinc-dust precipitation of gold from solution. The source of the chromium was the particular feldspathic and pyroxine ore.

Ore Mineral - an overview ScienceDirect Topics

Iron ore minerals, particularly hematite and goethite, are beneficiated by a combination of size fraction, preconcentration, and flotation in stages (Fig. 13.45).Iron ore requires removal of silicate impurities of a finer size by flotation for higher-grade products of +60% Fe. ROM ore at 400–600 mm is fed to a primary crusher with product set at –40 mm.
