The rule also defines processing wastes, as opposed to beneficiation wastes, which are subject to regulation as solid waste un- der Subtitle D.
To enrich the chromite values, researchers have treated the COPT in the different dry and wet beneficiation processes, and the summary of these studies are listed in Table 1.Most of these enrichment routes are stated to produce a marketable chromite-rich concentrate, but it generates more ultrafine tailings, which is again a waste for industry Murthy et al., 2011.
Recovery of chromite values, by physical beneficiation techniques, can be applied to support recycling, the remaining waste being transformed into non-toxic materials for safe disposal.
