Selective flotation separation of spodumene from feldspar ...

Spodumene and feldspar have similar surface sites, making separation difficult. • Addition of 30 mg/L SA before 0.2 mM DAA at pH 6 allowed minerals separation. • Spodumene has more Al sites than feldspar, and, thus, adsorbs more DAA. • Sodium alginate of selective depressant exhibited strong pH dependence. •

A magnetohydrostatic separator is based on the principle that when a paramagnetic solution (or ferro-fluid) is placed within an in­ homogeneous magnetic field, it will exhibit an apparent specific grav­ ity directly proportional to the magnetic field strength.
