Separating Pyrite & Blende Magnetism

The roast may be considered satisfactory when the separators make a recovery of from 85 to 90 per cent. of the total zinc in the raw concentrate, and yield a clean blende product carrying 1.5 to 2.5 per cent. iron due to pyrite. The iron content may, after the best work, reach a much higher figure, due to the presence of combined iron in the ...

Unraveling the Reaction Mechanism of FeS2

Iron pyrite (FeS2) is a promising lithium-ion battery cathode material because of its low cost and ultrahigh energy density (1671 Wh kg–1). However, its reaction mechanisms are still controversial. In this work, we find that different from the conventional belief that an intermediate phase Li2FeS2 is formed followed by Fe/Li2S composites at the initial …
