mining Blasthole stoping Britannica

mining - mining - Blasthole stoping: When the dip of a deposit is steep (greater than about 55 ), ore and waste strong, ore boundaries regular, and the deposit relatively thick, a system called blasthole stoping is used. A drift is driven along the bottom of the ore body, and this is eventually enlarged into the shape of a trough. At the end of the trough, a raise is driven to the drilling ...

Copper Mining and Processing Processing Copper Ores

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

Mining process Blasting Explosives are used to break up a rock formation and aid in the collection of ore in a process called blasting. Blasting generally the heat and immense pressure of the detonated explosives to shatter and fracture a rock mass.

The diamond mining life cycle Mining for schools

Once exposed, the ore in the pit is broken up by blasting. A single blast can break approximately 45,000 tonnes of ore. Once the ore is broken, excavators load the ore into haul trucks and transport it to a primary ore crusher where the diamond extracting process begins. Venetia mine is an example of open-pit mining.
