Monazite chemistry and its distribution along the coast of

The content of monazite ranges from 0.1 to 1.4%. A combination of unit operations like gravity separation, magnetic separation and electrostatic separation techniques were applied to the beach sand to recover monazite mineral. The data indicate that samples show a maximum yield of about 81% for THM and 0.5% for monazite.

ELECTROSTATIC SEPARATION

Electrostatic separation is done by initially charging the particulates or contaminants and then moving and concentrating them at the electric field boundary. Electrical separation was first demonstrated by Hohlfield in 1824 by clearing a smoked-filled jar with an electrified point. In 1884, Oliver Lodge attempted to collect lead fume using an ...
