Chromite is a cumulate mineral which is found in ultramafic portions of layered mafic intrusions or in serpentines and other metamorphic rocks derived from the alteration of ultrabasic rocks. Due to its high crystallization temperature, this mineral is often found in the lower parts of magma bodies from the fractional crystallization process.

Chromite Beneficiation Process</h3>The Problem with Chromite ProcessingThe Chromite Extraction FlowsheetChromite Process SummaryExperience indicates that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be designed to remove the chrome as soon as liberated by crushing and grinding. For example, if the chrome is not entirely freed until the ore is minus 16 mesh, it is obvious that the plus 16 mesh particles should be removed after stage crushing and grinding to prevent further reduction of the chrome and consequent

Chromite ore processing residue (COPR) is a waste byproduct of chromate production that contains high levels of hexavalent chromium (Cr[VI]). Although the high temperature chromite process was banned in several countries, its legacy still exists at numerous contaminated sites. For instance, New Jersey alone has over 2 million tons of waste COPR.
