Coarse-particle flotation applied to copper sulfide ores

• Feed Particle Size: This cell is being used industrially to float particles up to 6,000 µm (Phosphates). In the case of Cu sulfides, the ranges usually vary from 600 µm x 150 µm to 850 µm x 150 µm in some cases. • To optimize performance, it is recommended to work within a particle size distribution of 1:6.

RECOVERY OF VALUES FROM A PORPHORY COPPER

The efficiency of the froth flotation process has long been known to be strongly dependent on particle size. For sulfide minerals, good recoveries are typically achieved in industrial flotation circuits for particles in the 30 to 150 m size range. Particles outside this critical size are typically lost in industrial
