Which solution is used to sprinkle a fresh heap leach?

Is it barren or intermediate. Please support your answer with reasons

Thank you

Depends on the mineral and solution application strategy applied. In some operations PLS from the heap is recirculated back onto the heap, termed intermediate solution, to either increase the metal concentration in the PLS or to leach with lower pH or ORP.

Some sulfide operations will leach the fresh ore with Intermediate solution for the first part of the leach cycle and then apply barren for the last part of the leach cycle.

Depending on the mineral, operators will vary this concept but intermediate refers to the solution recirculated onto the heap for whatever process benefits they feel are achieved.

Which minerals and grades have you in your ore and what is your target by heap leaching?
