  • Chromite - an overview | ScienceDirect Topics

    Commercial chromite deposits that are large enough for mining are generally found in: (1) stratiform deposits, and (2) podiform deposits (Murthy et al., 2011; Papp and Lipin, 2001a). Other sources of chromite are laterites that are weathering products of peridotite. Laterites are more widely known as sources of nickel and cobalt (Papp, 2010).
