Amh. Shaikh et al., USE OF MAGNETIC SURFACTANTS IN THE HIGH-GRADIENT MAGNETIC SEPARATION OF ESSENTIALLY NONMAGNETIC CALCITE AND BARITE, Separations technology, 4(3), 1994, pp. 174-179
The minerals calcite and barite are essentially nonmagnetic and cannot
be recovered in the magnetic fraction during high gradient magnetic s
eparation. A novel concept of using magnetic surfacant to render the m
aterial magnetic has been investigated using manganese stearate and ol
eate as surfacants. The effect of various parameters has been studied.
The technique developed has immense potentiality.
