Copper mining is usually performed using open-pit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted into the drill holes to blast […]

The primary methods used to extract minerals from the ground are: Underground mining. Surface (open pit) mining. Placer mining. How are minerals extracted explain any one method? (i)Open cast mining: In this method minerals lying at shallow depths are taken out by removing the surface layer. (ii)Shaft mining: In it […]
The two most common methods of mining are surface and underground mining. The method is determined mainly by the characteristics of the mineral deposit and the limits imposed by safety, technology, environmental and economical concerns. What are the 2 types of mining?

Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earth’s surface—sometimes as far as 300 meters (1,000 feet). Miners travel by elevator down a mine shaft to reach the depths of the mine, and operate heavy machinery that extracts the coal and moves […]
Open-pit mining, such as the Kimberley Big Hole, involves removing the layers of sand and rock found just above the Kimberlite. The ore in the pit is then broken up by blasting. Once this ore is broken, it is loaded and then transported to a primary ore crusher where the […]
Underground hard-rock mining refers to various underground mining techniques used to excavate “hard” minerals, usually those containing metals, such as ore containing gold, silver, iron, copper, zinc, nickel, tin, and lead. It also involves the same techniques used to excavate ores of gems, such as diamonds and rubies. What do […]
