Learn what open-pit mining, also known as opencast mining, is and how it is used to extract minerals from the ground. Find out the benefits, materials, operations, and rehabilitation of this surface mining technique.
Open-pit mining, or opencast mining, is a surface mining technique used for large-scale operations. It involves extracting minerals from a pit by removing waste rock and overburden. Commonly used for minerals like copper, gold, and iron ore, requires heavy equipment such as trucks and shovels to efficiently extract the ore.
The open pit is opening the orebody from the surface by separate removal of ore and associated waste rocks. It is the most economic option for a deposit up to that depth where the economic ratio of ore and waste can sustain. There are many advantages in open-pit mining method namely:-Full visualization of exposed orebody and negligible ore loss,-
