within the ore, chemical characteristics of the ore, and the physical and chemical characteristics of the host rock. In some instances the ore can be mined and directly leached without any further processing, this is called run-of-mine ore. In many instances, the ore requires crushing and/or grinding to expose more surface area prior to leaching.
