Effect of microwave heating on magnetic separation of pyrite

15/09/2003  The performance of magnetic separation in removing mineral pyrite from coal can be improved by increasing the magnetic susceptibility of pyrite. Several studies have shown that magnetic susceptibility of pyrite can be enhanced by heating . However, the problem of heating pyrite in coal is that energy is wasted by also heating the coal .

Enhanced magnetic separation of pyrite from coal after ...

Separation of pyrite from coal would be facilitated by changing a portion of each pyrite particle to a more magnetic form. Studies included the measurement of the dielectric properties of different coal fractions at frequencies ranging from 1 MHz to 12 GHz. These values were then used to calculate the theoretical heating expected in these materials and their mixtures at 2.45 GHz. The ...

Enhanced magnetic separation of pyrite from coal after ...

Abstract: The objective of this research was to improve the magnetic separation of coal and pyrite by enhancing the magnetic susceptibility of pyrite in run-of-mine coal through the use of selective dielectric heating. Separation of pyrite from coal would be facilitated by changing a portion of each pyrite particle to a more magnetic form. Studies included the measurement of the dielectric ...

Microwave heating of coal for enhanced magnetic

15/01/2004  Microwave conveyor systems operating at 15 kW were used to treat run of mine coal. The microwaves were found to selectively heat the pyrite in the coal, causing the formation of pyrrhotite. It was stated that pyrrhotite could be removed by low-intensity magnetic separation. The quoted treatment cost per tonne of coal was US$22; this compared most favourably to traditional technologies such as ...

Pyrite - Wikipedia

Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold.The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.. The name pyrite is derived from the Greek πυρίτης λίθος (pyritēs lithos), "stone or mineral which strikes fire", in turn from ...

Mining equipment for Pyrite processing

Gravity separation is often used for processing medium particle disseminated pyrite ore with good separation performances. The specific gravity of pyrite is higher, which can reach to 4.9-5.2. Floatation method is mainly for fine disseminated pyrite ore. The choice of pyrite ore crushing method is according to ores characteristic, beneficiation site etc.Most pyrite ores contain sulfur and iron ...
