Research Progress on Activation Mechanism of Pyrite Flotation
Kuangchan zonghe liyong, 2023 Pyrite is one of the most abundant sulfide minerals in nature, often associated with lead, zinc, copper and other high-value sulfide minerals. Activators are normally used to improve the floatability of pyrite that inhibited due to high alkalinity.

Influence of N doping on structural and photocatalytic properties of hydrothermally synthesized TiO2/carbon composites [PDF]
Journal of the Serbian Chemical Society, 2023 N-doped TiO2/carbon composites (TiO2/CN) with different nitrogen content, were obtained starting from titanium isopropoxide and glucose, and by varying the amount of melamine, added to starting reaction mixture. For comparison, an undoped sample (TiO2/C)
