molybdenite and pyrite in the presence of biosolids and their main components (humic acids, glucose and serum albumin) as well as a commercial collector (Aero 6697). Fourier transform infrared spectroscopy (FTIR) was then used to gain a deeper understanding of the interaction of these compounds with these sulfide minerals. It aims to achieve a better understanding of the surface chemistry of ...

In Peru, at the Huanzala mine, the Uanuco Dept., pyrite crystals up to 20 cm. in size are found in quartz. In the Argentina, at the Santo Mino, Patagonia, pyrite crystals up to 23 cm. in size were found. In the, at the deposits Sparta and Ziegler, Illinois, discshaped concretions of pyrite are found – so called pyrite suns or pyrite dollar up to 12 cm. in diameter; crystals up to 30 ...
Under the oxidative roasting process, pyrite, as a major mineral in sulfidic mine tailings, can transform to iron oxides. Generated iron oxides, if exhibiting enough magnetic properties, can be recovered via magnetic separation resulting in partial mine tailings valorization. However, due to the presence of various minerals and sintering possibility, it is advantageous to remove impurities and ...
