·Details of the common iron ore and associated gangue minerals found in many iron ore deposits and iron ore products are given in Table three most common iron ore minerals are magnetite hematite the spelling hematite is preferred here over haematite and goethite which together account for an estimated > 99% of the iron minerals contained in
·Gallium Ga and germanium Ge critical elements have a wide range of applications and market value Extracting critical elements from coal gangue and combustion products can alleviate pressures on primary mining resources Understanding the transformation behavior of Ga and Ge during coal gangue combustion processes is significant for resource
The gangue sample was chosen from Xintai Shandong Province China Gangue basic characteristics were analyzed as shown in the Table 1 The sulfur content S% of gangue was % measured by total sulfur analyzer machine The moisture content was % which could provide favourable conditions for dry separation methods
The main gangue minerals of low density are quartz manganese and kaolinite The association between Fe minerals and gangue minerals is shown on Figure 4 0 00 10 00 20 00 30 00 40 00 50 00 60 00
·Phase transformation and separation of alumina and silica minerals in coal gangue are studied in this paper in order to prompt the resource utilization of coal gangue The results show that the phase transformation of kaolinite in coal gangue during high temperature calcination is in the following way kaolinite → metakaolin → spinel →
·The Bushveld Complex of South Africa contains almost 90% of the world s reserves of platinum group minerals PGMs In the flotation of PGMs there are significant challenges arising from the need to treat ever decreasing grades of the relevant ore deposits The major challenge in the flotation of these ore bodies is the control and management of the
·The reverse flotation of the iron ore with etheramine collector is significantly impacted when the iron bearing silicates and the kaolinite are present in the silicates gangue mineral complex This paper aims to propose a new amidoamine collector N [3 Dimethylamino propyl]dodecanamide for iron ore reverse flotation with a potential of removing
·The quest for sustainable mining processes has directed research towards environmentally friendly alternatives to conventional beneficiation practices with biosurfactants emerging as a viable option due to their lower environmental impact This study reviews the application of biosurfactants as bioreagents in mineral flotation exploring their production
·Magnetite and hydrogoethite account for and % of the component respectively; the proportion of iron distributed in gangue minerals and finely dispersed iron hydroxides
·The accumulation/improper treatment of coal gangue will not only lead to waste of land but also cause environmental pollution Especially the impact of radioactive elements on the surrounding ecological environment is widely concerned by many scholars In this study the concentration of radioactive elements uranium U and thorium Th of small scale coal
·The oxy hydroxide minerals of iron such as goethite occur in various mineral deposits including bauxite manganese and iron ores Goethite α FeO OH phase formation in iron ore takes place during the supergene metasomatic restoration of very fine grain chert along with gangue minerals which forms ferrihydrite FeO[OH] 3 ·nH 2 O and after dehydration
minerals such as quartz are typically less likely to break than those consisting of softer minerals like calcite or galena In addition minerals with prominent cleavages such as galena are also more likely to break In addition the internal texture of the ore particles the arrange ments sizes shapes and cleavages of the mineral

·Naturally hydrophobic gangue minerals such as carbonaceous materials and talc are widely associated with base metal sulphide and precious minerals in ore deposits [1 2 3 4 5 6 7] The examples include the presence of carbonaceous pyrite and talc in Mount Isa Copper Australia [] talc in Merensky Reef PGM deposits South Africa [] organic carbon in
Gangue refers to substances that are extracted along with desired minerals or ores due to their close association and are considered commercially worthless in mining For instance arsenopyrite was once considered a useless gangue mineral and dumped With research it was discovered to contain arsenic that is widely used today in
·Flotation is a complex process in which valuable minerals are separated from gangue minerals Leja 1982 The separation is based on the surface properties of each mineral phase present in the suspension Mitchell et al 2005 Çilek and Yilmazer 2003 Luz et al 2002 Flotation performance is dependent on several key factors such as particle size and
·Fundamentally important for the selection of a concentration method is the mineralogy of iron bearing minerals and gangue minerals presented to the feed to the concentration unit operation For instance the presence of liberated quartz as the major gangue mineral for a pellet feed size stream generally indicates that flotation will be the best
·The gangue minerals are mainly fluorite and barite with industrial production potential India and Brazil but also in South Africa the USA China and Malaysia The 20th century was an era of widespread monazite mining from beaches However because the inefficient utilization of thorium in monazite polluted the environment
·Fluorite CaF2 is considered a strategically important mineral as it is a raw material for many strategic industries Froth flotation is reported to be the most efficient and economically viable process for the production of an acid grade product with a CaF2 content of at least 97% Selective flotation of fluorite from gangue minerals calcite and barite is
4 ·The main ore or gangue minerals in mineral deposits generally record the physicochemical conditions that reflect the formation of mineral deposits Dupuis and Beaudoin 2011; Keith et al 2014 Consequently discriminant diagrams have been extensively developed based on the geochemical associations of minerals to discern the type of mineral
·The common gangue minerals associated with xenotime is as similar to monazite which consists of different silicate bearing minerals and heavy beach sand minerals Amphoteric collectors F74286 showed a better response than the conventional anionic collectors; studies showed that a concentrate of 34% of Y 2 O 3 content could be achieved
