  • Crushing And Milling

    Oct 25, 2015 Many commercial hard rock mines will do 80 or 100 mesh, but screen between steps, so the ore is not over crushed. Once you reach the desired size, you don't want to keep crushing. Even with leaching - you don't want to over crush - you can produce an ore that fluids won't flow through - think of trying to flush water through a bed of solid clay.
