Coarse chalcopyrite recovery in a universal froth

The NovaCell is a universal flotation machine in that it can give high recoveries of ultrafine, mid-range and coarse particles, in contrast with conventional flotation machines that have a limited range of sizes where high recoveries can be obtained. The NovaCell has been tested on a porphyry copper ore (1.0% Cu) ground to a top size of 600 µm.

Coarse Particle Recoveryin Large Capacity Flotation Machines

In 1973, the United States production, of marketable phosphate rock set a record in excess of 42 million tons. This production rate is expected to continue to increase, due to the growing international requirement for fertilizer, at a rate exceeding 5% per year well into 1977. This trend contrasts sharply with the reduced phosphate rock production levels of the 1966 1971 period.
