Magnetic enhancement of pyrite by caustic microwave treatment

摘要: Abstract A study is reported of the reasons for magnetic desulphurisation coal after microwave irradiation in a caustic slurry. X-ray diffraction, EDAX, ESCA and susceptibility studies were carried out on both mineral pyrite concentrate from by microwaves 2.45 GHz at 500 w up to 40 seconds presence 300 g/litre NaOH. The possible nature phase discussed terms Eh-pH diagram but no positive identification proved possible.
