Open Pit Mining Pros Cons Culture Society

Open-pit mining is a type of mineral or rock extraction that does not necessitate tunneling into the earth. When a desired mineral or rock is near the surface, companies typically opt for open-pit mining due to its lower costs and increased efficiency. Open-pits are typically dug in tiers and with angled walls to cut-down the risk of collapse or

Equipment Selection for Surface Mining A Review

A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.
