Outline of Final Research Achievements

This research proposes “galvanic microencapsulation” as a novel technique to passivate pyrite and prevent acid mine drainage formation. The most important achievements of this study are as follows: (1) galvanic interaction was more extensive under acidic conditions, (2) zero-valent iron was better than zero-valent aluminium in suppressing pyrite oxidation, (3) addition of phosphate in pyrite and zero-valent iron system produced iron-phosphate coatings on pyrite that limited its oxidation, (4) phosphate-enhanced galvanic microencapsulation was successfully applied in a ball mill using grinding balls as source of dissolved Fe, (5) galvanic microencapsulation could be used to improve coal and pyrite separation during flotation, (6) ferric phosphate coatings on pyrite could be formed even under very acidic pH (1-3) even without zero-valent iron, and (7) a potentially new process was discovered to create iron phosphate coatings on pyrite using acid mine drainage rich in ferrous ions.

Academic Significance and Societal Importance of the Research Achievements

The results are significant because galvanic microencapsulation could target pyrite and prevent acid mine drainage (AMD) formation. It could be applied to existing mineral processing plants using a ball mill. Finally, new ways to passivate pyrite using AMD and galvanic interaction were discovered.
