Beneficiation of low grade chromite for preparation of

some very low grade chromite samples were taken for laboratory scale beneficiation. Characteristics of the chromite samples Four chromite samples from rejected dumps and overburden materials of a chromite mine, were collected for their beneficiation. All the four samples are non-magnetic, soft in nature and black to brownish black in colour ... All such low grade fines need beneficiation. The objective of the iron ore beneficiation therefore, is to improve the iron content and decrease the alumina-iron ratio. Beneficiation and utilization of these fines would thus not only help in reducing the waste dump volumes

the extraction of primary commodities such as gold, copper, and uranium. As a result of the complex low-grade nature and varying characteristics of REE minerals in ores, it is important to expand the knowledge of the chemical and mineralogical characteristics, prior to developing beneficiation protocols for REE. Beneficiation of Camdag iron (oolitic) hematite ore containing limonite-hematite or goethite-limonite using gravity separation and high intensity magnetic separation, increases the grade of ore about 5-7% in concentrates with about 60% recovery by both methods (Guney et al., 2000).
