Energy Consumption In Mining Comminution -
For a single mine, average comminution energy consumption can be approximately 6,700 kWh kiloton. Grinding is accomplished by abrasion and impact of the ore with moving media such as rods rod mills, balls ball mills, or pebbles sized ore in AG SAG mills. These vary in size according the size of particle being processed.
Coal Prices And Outlook - U.s. Energy Information ...
In 2018, the average delivered price of coal to the electric power sector was 39.08 per short ton, which includes both spot and contract purchases. A more expensive coal is used to make iron and steel. In addition to producing electricity, coal is also used to produce coal coke, or coke, which is used in smelting iron ore to make steel.
Managing Water Consumption In Mining
But it isnt just the procurement of water thats a problem water extraction is also an issue. In many cases, especially with underground mining, water needs to be pumped away from a mine site, which can reduce the levels of ground water, deplete surface water or cause pollution to local rivers.
Mining And Refining Energy Efficiency
Such improvements, along with the addition of new, best available technology, refining capacity has driven an almost 10 improvement in global refining energy efficiency in just 5 years. Today, the average specific energy consumption is around 14.5 GJ per tonne of alumina, including electrical energy of around 150 kWht Al 2 O 3.
