· The modified hydrocyclone was able to diminish the copper concentration from 400 ppm to a minimum of approximately 25 ppm after 90 min of electrolysis. The metal ions were reduced at the cathode and a fraction of the deposit, approximately 12%, was recuperated as a metal powder, separated as a suspension by the hydrocyclone.

· Copper has a density of 4000 kg/m 2, and stones have a density of 1800 kg/m 2. The two-phase flow enters the hydrocyclone by the inlet pipe, and this boundary was used as a mass-flow-inlet boundary condition. Due to separation in the hydrocyclone, the flow was divided in two parts, one went to the spigot and the other went to the vortex finder.
