Polysaccharides-based pyrite depressants for green flotation …
Generally, the process of pyrite depression by polysaccharides occurs due to the hydrophilic surface coating phenomenon. This procedure is different from the depression process by inorganic materials where depressants like lime and cyanide alter pyrite's surface, preventing the collector adsorption (xanthate) [38].

Acid Mine Drainage (AMD): causes, treatment and case studies
Here, mining ceased in early 1980s but a considerable amount of acidic-water continues to be released from abandoned underground workings into the surface environment. In this case, pyrite content is the main cause of water pollution. When exposed to air, pyrite oxidizes and forms sulphuric acid once coming into contact with …

Extraction Of Copper | Mining, Concentration, Smelting
Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. …

Effects of pyrite on the spontaneous combustion of coal
The results indicate that pyrite can nonlinearly accelerate the process of spontaneous combustion. The coal sample with a pyrite content of 5 % has the largest CO release rate and oxygen adsorption as well. However, the coal sample with a pyrite content of 7 % has the largest rate of heat flow according to the results from the DSC tests.

Pyrite Mining
Pyrite often occurs in fine-grained, grey-green schist created by regional metamorphism and this describes the pyrite found in Stafford. Pyrite, also known as fool's gold, is a common sulfide mineral and ore of iron. Pyrite is rarely used in the manufacture of iron and steel, but by simply mixing pyrite with water, sulfuric acid may be produced.

Pyrite | Earth Sciences Museum
Pyrite seldom forms in fresh-water environments. The formation of pyrite crystals depends mainly on the iron content of the sediment. The process of pyrite formation in sediments results from the action of bacteria, which reduce sulphate ions (dissolved in the pore water) to sulphide. If there is iron present, iron sulphide crystals begin to grow.
