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.
