The concentration of different maceral groups and minerals in coal influence the quality as each of them behaves differently during heat treatment. The purpose of this study is to know how these are behaving at different ...

Chromite overburden (COB), considered as a waste material with 46% Fe and 0.8% Ni, is the only source of nickel in India. Iron and nickel from COB were recovered through reduction roasting, magnetic separation and smelting. ...

Beneficiation of low-grade ore is of critical importance in order to meet the growing demand for coal and mineral industries. But, low-grade ores require fine grinding to obtain the desired liberation of valuable minerals. ...

Metal halide perovskite nanocrystals (NCs) have shown tremendous progress because of their unique inherent photophysical properties, which driven them for potential application in the fields of light emitting diodes, solar ...

In this study the structural and optical properties of Fe-doped SnO2 (Sn1-xFexO2, for x = 0, 0.03, 0.05, 0.07) nanoparticles synthesized by co-precipitation technique and using short durations of sample sintering is reported. ...
