Some researchers have found that the calcination of natural pyrite at 550-600 ℃ under N 2 atmosphere can desulfurize it into monoclinic pyrrhotite (Eq. 11), which has been proved to …

This research provides a new, environmentally friendly, biodegradable, and cost-effective depressant reagent, namely tricarboxylate sodium starch (TCSS), in chalcopyrite and …

Monoclinic and hexagonal pyrrhotites leached in 1 mol/L HCl and exposed to the air at 100% and ϳ10% relative humidity for up to 5 months were studied using X-ray diffraction, Fourier …

2024年2月19日 · In this work, we first investigated the phase transformation of natural pyrite under different annealing conditions in inert atmosphere by using XRD Rietveld refinement …
