  • Converting Process

     · In froth floatation, an ore pulp is agitated and air is blown through it to produce froth. Some mineral particles, mostly sulfides, attach to their air bubbles and are concentrated in the froth, which is skimmed off from time to time. The copper is concentrated from 0.5% to 1% Cu until 24% to 30% Cu.
