You now have the unit capacity. Then take the volumetric feed rate of the new ore per time. Divide the unit capacity by the feed rate and you have the nominal retention time. Say your unit capacity is 1/2 cubic meter and you are feeding 6 cubic meters per hour, your retention time would be about 5 minutes.
