particle size copper froth flotation milling

  • 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.
