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 processThere are many different types of mills and many types of materials processed in them Historically mills were

  • specific energy consumption gold mines

    Assuming similar specific energy requirements for other sites, comminution of gold and copper ores can be expected to consume about 0.2% of global, and 1.3% of Australia's electricity consumption. Efforts to reduce this figure should be aimed at the top third of consumers as they are responsible for 80% of the total consumption.

  • Market Underestimates Energy Consumption By The Gold

    Jan 25, 2018· While the gold mining industry reports energy as only 15-20% of its total production costs, the total amount consumed by the industry is much higher. The market underestimates the amount of energy consumed by the gold mining industry because of the way it is listed in their financial statements. Thus, it takes a great deal more energy to produce gold than the market realizes.
