The economic deposits of cassiterite are known in two types of geological occurrences – primary vein or hard-rock deposits and secondary placer deposits (Falcon, 1982, Rao, 1992). The mineral assays about 0.4–1.5% Sn (occasionally 5–6%) in the hard-rock deposits and placer deposits are slightly poorer in grades ( Bulatovic, 2010 ).

Ion-adsorption deposits (weathering crust deposits) are a unique type of RE deposit with HREEs that are characterized by the adsorption of RE ions on clays, dominantly kaolinite and halloysite. These deposits are weathered granite on the bare …

However, the quartz mineral resources that can be used for industrial applications mainly include 7 industrial types of ore deposits, including natural crystal, quartz sandstone, quartzite, vein quartz, powder quartz, natural quartz sand, and granite quartz. In China, the quartz mineral resources are abundant and spread all over the …

A productive quartz deposit has been developed in Colombia near the town of Muzo, Boyaca, Colombia. 5 It consists of one principal vein and numerous subordinate veins. These veins are localized by fractures in a drag fold structure on the vertical limb of a tight anticline in the Cretaceous slates (Villeta formation).

By using beneficiation techniques, quartz, sodium feldspar, and potassium feldspar can be separated from weathered granite, removing colored …

The development of plasma methods for quartz-concentrate beneficiation requires a wide range of experimental studies to investigate the influences of design features of electric arc plasma generators and their energetic characteristics on the beneficiation efficiency, diameter dispersion, and contami-nation level of quartz concentrates. 2.

Each rare earth deposit is unique and is always composed of a variety of minerals. For example, the Baiyun Obo deposit, the largest rare earth mine in production in China, contains bastnaesite, monazite, fluorite, magnetite, barite, calcite, quartz, feldspar, etc. (Cheng et al. 2007a, b).In order to make a rare earth project economically feasible, …

The unutilized iron ore fines (IOF, − 10 mm, 45% to < 60% Fe(T)) left at various mine sites during blasting and processing are rich in goethetic-hematite associated with high clay and considered a potential iron ore resource. The variation of loss on ignition (LOI) from mines to mines is based on the goethite and clay mineral content. The clay …
