An assessment of the mechanisms and kinetics of pyrite transformation in inert and oxygen-
containing atmospheres at elevated temperatures has been performed based on a literature …

Recovering gold from sulfide refractory gold ore has been an important guarantee for the
sustainable development of gold industry, while there are many challenges in the treatment …

Oil shales and coal have considerable amount of pyrite which undergoes various thermal
transformations during their processing or combustion. Reactions and changes in pyrite …

Manipulating magnetic interactions in diluted magnetic quantum dots (DMQDs) is a
fundamental research field due to the potential for developing robust magnetic …

The conversion of As vapor released from coal combustion to less hazardous solids is an
important process to alleviate As pollution especially for high-As coal burning, but the roles …

A series of thermodynamic calculations are performed for the roasting of pyrite in changing
temperatures and atmospheres. The relationship between ΔrGθ and temperature in the …

Pyrite is common in coal gangue formed in a reduced environment and has a significant
influence on the recycling utilization of coal gangue. Four types of pyrite with different …

A comprehensive review is presented of the recent contributions Mössbauer spectroscopy
has made in materials science and engineering. After a brief introduction to the basic …

H 2 O concentration in an oxy-fuel furnace is higher than that in a conventional air
combustion furnace. Pyrite is a dominant factor that contributes to slagging in pulverized …

In this study, a modified fluidized bed reactor was used to roast pyrite concentrate (PC). To
analyze the pyrite conversion and fluid flow in the bed, a 2D model incorporating the Euler …
