PDF Effect of Inorganic Ions on Pyrite Catalyzed Fenton Reaction

Mineral pyrite (Alfa Aesar) was first manually ground. Then, mechanical milling was performed at 600 rpm in an ethanol medium (planetary ball mill Retsch PM 100 CM). Zirconium oxide balls (diameter: 2, 5 and 10 mm) were used for milling by balls to powder weight ratio of 10:1. The surface areas of the materials were calculated using the Brunauer-

Improvement of flotation and suppression of pyrite

In this study, GME treatment of pyrite in a ball mill with steel ball media and phosphate was investigated. Iron phosphate coatings were formed on pyrite that passivated the mineral and limited its oxidation. For the coating to form, sufficient supply of oxygen was crucial during GME treatment.
