Energy Consumption in Mining Comminution

Mining energy consumption contributes to mining operational costs and occurs at all stages of the ore recovery process blasting excavation crushing transport and grinding comminution For example the copper mining industry is expected to consume terawatt hours TWh in 2025 an increase of percent from 2013 [11] New mining

PHASES OF A MINING PROJECT Home ELAW

For example the copper content of a good grade copper ore may be only one quarter of one percent The gold content of a good grade gold ore may be only a few one hundredths of a percent Therefore the next step in mining is grinding or milling the ore and separating the relatively small quantities of metal from the non metallic material of the ore in a process called beneficiation

Genera Processing Technology For Minerals

After mining the mineral ore is mined from underground then the first procedure is to crush the big lump rock to small size for further processing During this stage normally scrub washing will be applied for materials with much mud Besides grinding is a very important stage to liberate the mineral ore from the gangue veins which makes subsequent beneficiation sufficiently
