Opencast mining is also known as open-put mining, open-cut mining, surface mining and also as strip mining, the later term being commonly used in the U.S.A. for opencast mining of coal. The overburden and the mineral, coal, are excavated in long strips of a few metres thickness and hence the operations are termed strip mining.

What is Open Cast Mining? Open-cast mining is a method of extracting minerals, coal, or other geological materials from the earth by removing the layers of soil and rock above the desired resource. This technique is used when deposits of commercially viable minerals or rock are found near the surface. The process involves:

Open-cast Mining. Open-cast mining is one of the most popular surface mining methods mostly employed for bedded deposits. The kind of minerals or rocks mined this way are found near the surface; where the overburden (surface material covering the valuable deposit) is relatively thin or the material of interest is structurally unsuitable for tunneling.

Anode Casting; Electro-Refining; How is copper mined? Copper is usually mined in two ways: open-pit mining and underground mining. Open-pit mining is used for copper deposits closer to the surface. Enormous machines dig up the ground in stair-stepped layers (called "benches") until the copper is extracted using drilling equipment and ...

Open pit mining, also known as open-cast or open-cut mining, is a surface mining technique used to extract minerals, rocks, and precious resources from the Earth. The process involves digging a large pit in the ground to access the desired materials, and it is widely employed for mining commodities like copper, gold, coal, and iron ore.
