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.

For bulk material (eg, iron ore) once reconditioned, the product is stacked in stockyards and then it is transported to the port. For product types that come in various grades of quality, such as iron ore, an additional step known as product blending takes place before the product is loaded onto the ship and transported to the customer.
