Is this for an existing operation where you want to know what is going on or for a new operation?

If it is an existing operation an approximation can be made by knowing the flow rates and the volumes of the leach tanks and adsorption system. It is just volume divided by flow rate.

For a new operation this is what test work is for to determine this. A series of tests are run at different flow rates for a given volume until an economical rate is reached.
