I would like to know the effects leaching time can have on recovery of gold?

Residence time in the CIL circuit is the time taken for the slurry to flow through the tanks, and is an important operational consideration. The longer the gold particles are in contact with the cyanide in the slurry the more gold that will be leached.

Residence time is determined by the volume of the tanks (which is fixed), the slum' flowrate and the slurry density.
