An open pit means that more ore can be extracted at a lower extraction cost. The offer also means that lower ore content can be extracted, which means that more ore must be extracted every year to achieve profitability in the mine. This is the case for example with the open pit called Aitik, where large quantities of low-grade ore are extracted.

30.03.2022Open-pit mining is a process of digging the earth's surface to extract ores or minerals present in a shallow layer. In case of mineral ores present deep down, we require an underground tunnel to remove them. That's not under an open atmosphere like open-pit mining. The shape is already determined and optimized for maximum profit in surface mining.

30.04.2021Open-pit mines are typically enlarged until either the coal is exhausted, or an increasing ratio of overburden makes further mining uneconomic. When this occurs, the exhausted mines are sometimes converted to landfills for disposal of solid wastes. However, some form of water control is usually required to keep the mine pit from becoming a lake.

Open-pit mining, also known as opencast mining, open-cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth.

The open pit mining can be defined as a surface excavation for the removal of minerals of economic interest. It can be used for the exploitation of metal and nonmetallic mineral deposits near the surface, usually with depths less than 150 m.

In all, more than 90 countries produce gypsum. In most open pit gypsum operations, benches are drilled and blasted using ammonium nitrate as the explosive. Because gypsum is so soft, most drills can drill through it at a rate of roughly 23 ft per minute. Sometimes the drill holes become wet, which can cause problems with the ammonium nitrate.
