importance of gangue

Nonetheless gangue minerals can be just as important as ore minerals in providing scientific clues to the origins of hydrothermal ore deposits particularly in regard to their age and the origins of the water in the oreforming fluid Table 2 Examples of common hydrothermal ore minerals

Gangue is one of the largest accumulating solid and is particularly rich in pyrite Therefore pyrite recovery from gangue is not only significant for the environmental protection but also for the development and production of chemicals

Gangue rejection is the process of separating and disposing the poorest lowquality lowvalue material in an ore feed prior to further downstream processing Simply put the focus is on the waste to reject rather than the mineral to recover Economic benefits are gained when the gangue volume is replaced with useful material of a higher grade

Blast Furnace Operation In modern steel making slags originate in a blast furnace from impurities in the iron ores known as the gangue the flux and coke ash This is a complex mixture of silica alumina sulfides and oxides of calcium and magnesium as well as smaller amounts of manganese and iron oxides

Apr 13 2017 · Coal gangue is a significant residue during the processing of coal mining and coal washing which accounts for approximately 10–15 of raw coal production and becomes one of the largest industrial residues in China 1

QuoraNov 28 2017· Gangue is valueless mineral associated with a valuable mineral that can economically be utilized which is an ore eg pyrite FeS2 will be a gangue mineral associated with say sphalerite ZnS if the latter mineral can be utilized ANT ORE MINERALS Mineralogy Petrology and Some tellurides are also important ore minerals such as calaverite sylvanite

Gangue minerals usually consist of common silicate oxide carbonate and sulphate minerals that do not contain sufficient concentrations of valuable metals Nonetheless gangue minerals can be just as important as ore minerals in providing scientific clues to the origins of hydrothermal ore deposits particularly in regard to their age and the

Gangue rejection is the process of separating and disposing the poorest lowquality lowvalue material in an ore feed prior to further downstream processing Simply put the focus is on the waste to reject rather than the mineral to recover Economic benefits are gained when the gangue volume is replaced with useful material of a higher grade

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 acidgrade product with a CaF2 content of at least 97 Selective flotation of fluorite from gangue minerals eg calcite and barite is challenging because these

In modern steel making slags originate in a blast furnace from impurities in the iron ores known as the gangue the flux and coke ash This is a complex mixture of silica alumina sulfides and oxides of calcium and magnesium as well as smaller amounts of manganese and iron oxides

Pyrrhotite crystallises as either a hexagonal or monoclinic structure both of which can occur in ore deposits In general pyrrhotite is not considered as a valuable mineral unless it contains considerable amounts of other metals like nickel or copper In fact it causes numerous problems in flotation including intensive oxygen consumption which results in poor

Double Roller Crusher plays an Important Role in Coal Gangue Crushing authordahua time20200511 Coal gangue is the solid waste discharged in the process of coal mining and coal washing It is a kind of black gray rock with lower carbon content and harder than coal which is associated with coal seam in the process of coal forming

Gangue particles GP are an important part of solid filling materials in coal mines The compression characteristics CC of gangue determine whether it can effectively control roof subsidence The particle size distribution PSD of GP is the main factor affecting the CC therefore it is important to find the optimal size distribution of GP and to investigate the macrodeformation and

Dewatering is an important process in mineral processing The purpose of dewatering is to remove water contained in particles This is done for a number of reasons specifically to enable ore

Ore a natural aggregation of one or more minerals that can be mined processed and sold at a profit An older definition restricted usage of the word ore to metallic mineral deposits but the term has expanded in some instances to include nonmetallics Although more than 2800 mineral species

feedstock materials due to its high Fe content low gangue and chemical purity • On average Pig Iron makes up between 510 percent of the global EAF metallics charge In some parts of the world where scrap is scarce Pig Iron can be used at up to 60 percent of the charge

alumina content Coal gangue is a hazardous byproduct of the coal mining industry and the average production of coal gangue is about 10 15 of raw coal production 15 The main composition of coal gangue is also SiO 2 and Al 2 O 3 The properties of ceramic proppants obtained by flint clay and coal gangue should be in some respects

Feb 15 2017 · The total accumulative stockpiles of gangue in China comprise 45billion metric tons and approximately 659million tons of additional gangue are generated per year Considering the stacking characteristics are highly heterogeneous the potential cancer risks from the presence of polycyclic aromatic hydrocarbons PAHs remain elusive
