The P80 separation is the particle size for which 80% of the cyclone overflow is finer than that size. For example, if a sample of cyclone overflow was passed through a bank of screens and 80% of the sample was found to pass through (finer than) the 75m screen then the P80 point for the overflow is 75m.

After mining, large pieces of the ore feed are broken through crushing and/or grinding. This step creates particles that are either mostly valuable or mostly waste. Concentrating the particles of value in a form supporting separation enables the desired metal to be removed from waste products. Ore bodies often contain more than one valuable metal.
