英文摘要
Pyrite associated with coal generates SOx causing acid rain during coal combustion. In coal preparation, pyrite is rejected as a gangue mineral using the physical separation technique such as froth flotation and wasted into tailing pond. In the froth flotation, pyrite is frequently entrapped in froth together with valuable mineral due to its hydrophobic nature. Formation of acid mine drainage due to the air-oxidation of pyrite in tailing pond is also a serious problem. In the present study, carrier-microencapsulation (CME) is proposed to suppress both the floatability and oxidation of pyrite in coal preparation.
