Open-pit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. This surface mining technique is used when mineral or ore deposits are found relatively close to the surface of the earth.
Open pit and open cut mining are the least expensive techniques for the ore extraction. Overburden and stripping ratios are important in determining whether a deposit is to be mined. The stripping ratio describes the unit of overburden that must be removed for each unit of crude ore mined. A typical open pit iron ore mine is shown in Fig 1
2021-1-22 Open-pit mining of direct shipping hematite ore, using rotary drills, small shovels and trucks, commenced in 1963 at F’Derik, Rouessa and Tazadit. Primary and secondary crushing is done at Tazadit and the ore is railed to Nouadhibou in trains of up to 220 cars, each carrying 84t.

8.2.3.1 Open pit mining. Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths.
