2019-4-8 A series of thermodynamic calculations are performed for the roasting of pyrite in changing temperatures and atmospheres. The relationship between ΔrGθ and temperature in the range of T = 300–1200 K shows that, depending on the atmosphere it is in, reactions of pyrolysis, oxidation or reduction can occur. Both the pyrolysis of pyrite in an inert

MICROWAVE ROASTING OF PYRITE TAILINGS AND
2017-9-15 The roasting of copper pyrite and iron ores, the pyrites of coal and shale using microwave radiation has been investigated. The test results showed that there was a continuous mass loss from room temperature to 700 oC with a total mass loss of 12%. The major mass loss of over 10% occurred between 400 oC and 600 oC in coal pyrolysis. This occurred due to the sulphur combustion of and reaction of exothermic heat release from pyrite from the sample. The real and relative permittivities were very high and increased significantly with decreasing frequency. Beyond 400 oC the permittivity decreased and this was attributed to the removal of most of the combustion of pyrite. The copper pyrite

Chemistry and phase evolution during roasting of
2017-8-1 During the roasting of Tl-rich pyrite ores in the sulfuric acid industry, Tl sulfides initially in the pyrite ores, vaporized into the flue gas prior to oxidation. However, much of the Tl does not vaporize during the roasting (Yang et al., 2009).

Oxidation mechanism of pyrite concentrates (PCs)
2020-7-1 The circulating fluidized bed (CFB) roasting process is a promising way to utilize pyrite concentrates (PCs) which are byproducts in nonferrous metal production processes. The oxidation mechanism of PCs was investigated under typical CFB roasting conditions with the temperature of 850 °C and oxygen concentration of 1–21% on a drop tube furnace.
