PwC Open pit mining Mining Methods 5 Open pit mines are used to exploit low grade, shallow ore bodies. However, some pits are quite deep about 1 km. The mining rate is greater than 20,000 tonnes per day (tpd) but is usually much greater.
There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
May 22, 2020· Mining is the process of mining stuff out of the ground. Any material that cannot be grown must be mined. Mining things from the ground is called extraction.Mining can include extraction of metals and minerals, like coal, diamond, gold, silver, platinum, copper, tin and iron.Mining can also include other things like oil and natural gas.. Some mining is done by scraping away the soil (dirt

Iron, copper, nickel, and gold mines; Deposits where both the ore and rock are breakable; It is widely believed that surface mining is more productive than most underground mining methods, with the exception of block caving, which has a comparable rate of productivity.
Underground mining is used for gold, platinum, zinc, lead, and increasingly, coal. As can be seen, surface mining is much more advantageous than its counterpart. However, when an outcropping ore body stretches deep inside the Earth, surface methods can be used to begin the mining operation, which then need to be continued further by underground
