A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().
Few heapleaching plants today are operating with HPGRs; however, one successful installation located in Mexico has seen significant improvements in gold recovery since the addition of an HPGR to its stage crushing/leaching circuit. The typical application of HPGR in heap leaching will be replacing the conventional tertiary crusher.
