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.
Major Mines & Projects | Wafi-Golpu Project
The Golpu flowsheet will be commissioned in two stages with the additional ball mill circuit brought on later to match the increased tonnage profile, resulting in a SAG/ball mill configuration with the two ball mills operated in parallel. The Golpu pyrite circuit will be commissioned the following year.

For air atmosphere the laboratory ball mill was filled with pyrite and 400 ml water and kept open the mill for 5 min to have the air and then pyrite was wet-ground for 1 h. Pyrite in N 2 atmosphere also generated H 2 O 2 as Borda et al. (2003) showed that pyrite can also generate H 2 O 2 in the absence of molecular oxygen.
