Residual xanthates in mineral processing wastewater cause severe water pollution and potential air pollution in mining areas In this work the subsequent degradation behavior of xanthate after adsorption on pyrite surface was investigated and confirmed for the first time using potassium ethyl xanthate PEX as a model xanthate collector
Pyrite ore is widely used in sulfuric acid production chemical industry and other fields With the continuous development of pyrite resources how to efficiently and economically process different types of pyrite ores has become the focus of mining companies The selection of mineral processing methods is mainly based on the selectivity characteristics of the ore so this
Pyrite flotation separation and encapsulation in tailings dams is proposed as a viable way to chemically stabilize tailings Characterization of potential acid mine generation in tailings led to an innovative process in which acid generating pyrite is separated by flotation from the coarse tailings and incorporated into the slime zone This creates pyrite free neutral tailings
The costs associated with extracting and processing lithium from pyrite are still being evaluated but initial estimates suggest that they could be competitive with conventional methods
This study evaluates the recycling/thermochemical conversion process of pyrite tailings and gypsum residues from the Boliden Aitik mine using thermodynamic modeling Tailings from the mining of sulfidic minerals containing metals such as copper Cu zinc Zn and lead Pb represent the largest volume of waste generated in the mining
Alteration during mining especially in open pit operations and during ore storage should also be taken into account Download to read the full chapter text Chapter PDF Similar content being viewed by others Applied Mineralogy for Complex and Profound Mineral Processing H Reverse flotation process used on pyrite complex ores in 7
Case study for avoiding treatment in perpetuity the Brukunga pyrite mine example Scott et al 634 Mine Closure 2011 Alberta Canada The legacy of mining and mineral processing is an area of 155 ha of disturbance encompassing waste rock dumps tailings storage quarry and a townsite and acid and metalliferous drainage
However pyrite waste is potentially reusable Therefore this study aimed to evaluate possible ways of waste and effluent valorization that are generated during the processing of coal mining pyrite R1 Raw R1 were subjected to two consecutive leaching processes in distilled water 20 g/L 70 °C under mechanical stirring for 40 min
The properties of surface films on pyrite have been studied through electrochemical techniques of cyclic voltammetry and AC impedance measurements The characteristics of the surface films depend on the conditions of oxidation and the source of pyrite At potentials near V some pyrites have large values of polarization resistance showing a certain degree of passivity

The coal mining industries generate a considerable volume of pyrite rich tailings FeS2 However pyrite waste is potentially reusable Therefore this study aimed to evaluate possible ways of
Pyrite FeS2 is one of the main tailings derived from coal mining When processed pyrite has several applications with high value added in contrast if improperly discarded it causes major
Processing of mining wastes rich in critical metals both aids in meeting this demand and aligns with achieving a circular economy mining system However to extract these minerals processing technologies need to be developed or adapted to mining wastes which have different properties particle sizes poor mineral liberation compared to
The coal mining waste consist of three fractions rich in pyrite rich in clay minerals and rich in carbon [6] In addition to iron and sulfur the XRF chemical analysis Table 1 in agreement with the X ray diffractogram Fig 1 a shows that coarse pyrite has quartz SiO 2 and calcite contamination CaCO 3 which decomposes into CaO CO 2 and the other oxides
The Mongolian and Russian Erdenet Joint Mining and Concentration Enterprise processes in a year on average 26 million tons of sulfide ore of complex mineralogical composition which contains about million tons copper and 3500 tons of molybdenum concentrates Research has been carried out on combined processing of flotation pyrite

Researchers found that when minerals such as pyrite are enriched with arsenic gold can enter mineral structural sites by directly binding to arsenic Why gold loves arsenic
The Poderosa mine site 37°44 55 N; 6°39 15 W is a historical copper mine situated about 8 km north west of the world renowned mining district of Rio Tinto in western Andalusia Spain Fig 1 It is a volcanic hosted massive sulfide deposit capped by gossan in which chalcopyrite occurs as an accessory mineral associated with pyrite
