Open pit mining offers several advantages that make it a preferred method for extracting minerals: 1. Efficiency. Open pit mining allows for large-scale operations, enabling the extraction of substantial quantities of minerals efficiently. This makes it economically viable for minerals that are dispersed over a wide area. 2. Accessibility
The excavation usually has stepped sides to ensure the safety of the miners and a wide ramp where equipment can travel, allowing the product to be removed efficiently from the site. Open-pit mining is practical when the ore-bodies of the rock are large and located closer to the surface. Advantages of open-pit mining include: 1.
