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 processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
Canada Mining Innovation Council (CMIC) and CMIN to launch the pilot project to identify the potential for energy recovery from grinding circuits. The importance of energy-efficient grinding circuits lies in the fact that Canada has 62 concentrators (Geological Survey of Canada, 2014) of which 70% are located in Ontario, Quebec and British Columbia

Gold mining in Alaska, a state of the United States, has been a major industry and impetus for exploration and settlement since a few years after the United States acquired the territory from Russia. Russian explorers discovered placer gold in the Kenai River in 1848, but no gold was produced. Gold mining started in 1870 from placers southeast of Juneau, Alaska.

The -8 mm crushing circuit product reports to the 3,500t live capacity fine ore bin. Ore from the fine ore bin is fed to the grinding circuit via conveyor, quicklime is added to the belt for pH adjustment. The grinding circuit consists of a primary and secondary mill in closed circuit with hydrocyclones.
These mining methods provide the greatest control to enable commercial scale selective mining that minimizes dilution and maximizes ore recoveries and grade. Processing Facility The processing facility has been designed as a conventional two-stage crushing and screening circuit, followed by two-stage grinding to achieve a target grind P80 of 75μm.
