mineral resources other than ex mining area. A mineral is a naturally occurring substance formed through geological processes that has a characteristic chemical composition, a highly ordered atomic structure and specific physical properties. Heavy minerals refers to minerals with a specific gravity (SG) greater than that of quartz (SG = 2.7) [3].

Heavy liquid separation is a gravity concentration method based on the simple principle that a material whose specific gravity is less than the liquid's will float and a material with a greater specific gravity will sink. The use of a heavy liquid with uniform chemical and physical properties potentially offers the best method for gravity ...

13.24.3.5.1 Heavy indicator minerals. Heavy and/or resistate minerals can provide a good indication of primary geology and the presence of some types of mineral deposits (Averill, 2001). The effectiveness of heavy indicator mineralogy is dependent on the minerals being source-specific and having useful properties that complement their high ...

Many heavy minerals are resistant to physical weathering and erosion, can therefore withstand sediment reworking. Some heavy minerals also have variable properties that can accurately indicate their ultimate source. In the lab, heavy minerals are separated from light minerals in heavy liquids and mounted on glass slides for examination.
