Magnetic separation performs poorly with non-magnetic or only weakly magnetic materials like gold and graphite. Using it as the sole method won't effectively process these ores. Thus, magnetic separation applications remain constrained regarding suitable ore bodies. Most mineral separations still require gravity, froth flotation, or other ...

Magnetic agglomeration separation is a separation method where strongly magnetic minerals in small particles selectively form magnetic agglomerates under the magnetic force, gravitational force, and shear force in the low-frequency electromagnetic field, and then they can be separated from the gangue and mineral combination.

Magnetite-(apatite) ore deposits are interpreted as being formed by the crystallization of iron-rich ultrabasic melts, dominantly generated by the interaction of silicate melts with oxidized P-F-SO4-bearing sedimentary rocks. This hypothesis is supported by geologic evidence, experimental studies, numerical modeling, stable and radiogenic isotope …
