  • Method of reducing carbon levels in fly ash
    Publication number: 20020189497
    Abstract: There is disclosed a method of reducing carbon levels in fly ash. The method comprises the steps of: (a) placing the fly ash in a microwave reactor; (b) exposing said fly ash to microwave radiation in the presence of carbon-free material so as to raise its temperature to at least 600° C. while agitating the fly ash in the presence of oxygen; and; (c) terminating exposure of said fly ash to said microwave radiation when the carbon content of the fly ash has fallen below a predetermined value.

  • Method for the microwave induced oxidation of pyritic ores without the production of sulphur dioxide
    Patent number: 5972302
    Abstract: Pyritic ores are heated with microwave energy in a fluidized bed to a temperature in the range of approximately 573 degrees Kelvin to 823 degrees Kelvin with a controlled amount of oxygen to promote the oxidation of the pyritic ores according to the reaction: 2FeS.sub.2 +3/2 O.sub.2 .fwdarw.Fe.sub.2 O.sub.3 +4S, thereby preventing the production of sulphur dioxide.
