    The Mineral Liberation Analyser data indicated that increased milling does not relate to increased chromite grades and recoveries, particularly for the disseminated PCMZ type ores based on laboratoryscale gravity concentration The recovery is controlled largely by the chromite chemistry The results also showed that the MCHR samples that underwent a preflotation stage before gravityChromite, the principle ore of the element chromium, is a commercially valuable mineral However, due to mining restrictions and the fact that Chromite is not commonly found in crystallized form, it is not wellrepresented in mineral collectionsChromite: The mineral Chromite information and picturesWhat is Chromite? Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4) It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromitebearing rocks are altered by heat or weathering Chromite is importantChromite: The only mineral ore of chromium metal
