    1975-6-1  Since the capital and operating costs increase with increasing magnetic field strength, the key to economical superconcentrate production by high-intensity wet magnetic separation is starting with an ore for which the iron minerals liberate at a relatively coarse size. It is essential that a minimum of locked particles be present.

    Pilot plant and commercial operations have shown that high-intensity wet magnetic separation is well adapted to meet this specification with high recovery and attractive capital and operating costs. Tests with the Jones separator have produced superconcentrates containing less than 1.5% silica with over 90% iron recovery from preconcentrates produced by sizing or by gravity or low-intensity magnetic separation.
