Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. 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 …
Persians, Greeks, and Romans used this method to mine for salt, marble, and granite. Open-pit mining is commonly used to extract building materials like limestone and marble. An open-pit mine produces a large amount of ore without the expensive process of removing overburden, as the ore is often close to the surface and spread over a large …

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.
