Open-pit, open-cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburdenis relatively thin or the get price

Typical Open Cut Grades. Gold is generally extracted in open-pit mines at 1 to 2 ppm (parts per million) but in certain cases, 0.75 ppm gold is economical. This was achieved by bulk heap leaching at the Peak Hill mine in western New South Wales, near Dubbo, Australia. Nickel, generally as laterite, is extracted via open-pit down to 0.2%.get price

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.

If the gold is located close to the surface, it’s mined with open-pit mining techniques. Gold that’s located farther below the surface is collected with underground mining methods. Large pieces of ore are made into smaller pieces, and then the sand grain-sized pieces are mixed with a cyanide solution to create a watery, mud-like mixture.get price
