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... Extraction of natural resources.

Lopez not allowing a 700-hectare open-pit mine to extract
Open Pit mining - Used when mineral is distributed widely and evenly through rock formation, or when the ground is unsuitable for tunnels. - Involves digging a large whole and removing ore and the unwanted rock that surrounds the ore. how to lose weight fast with easy exercises If the ore lies close to the surface, open cast pit technology is employed. Here the overburden is excavated to reveal the ore body for easy extraction. If the ore lies deep underground, the underground block caving technique is employed. Here large blocks of ore are undercut and allowed to collapse under their own weight. The resulting rock is removed to the surface for processing.

How To Extract Copper From Open Pit Mining
Open-pit mining is a type of mineral or rock extraction that does not necessitate tunnelling 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.
- Surface mining techniques are generally cheaper than subsurface mining techniques. The closer a deposit is to the surface the cheaper it will be to extract. The ideal situation is a deposit close enough to the surface to that it can be removed by the open-pit method.
