Give two minerals that are mined using open-pit mining?
Two minerals commonly mined using open-pit mining are copper and coal. In open-pit mining, large holes are dug to access the mineral deposits near the surface, making it an efficient method for extracting these minerals in large quantities.
Is gold mining open-pit or underground?
Gold mining can be both open-pit and underground. Open-pit mining involves digging a large pit to extract ore, while underground mining involves tunnels and shafts to access ore deposits below the surface. The choice between the two methods depends on factors such as the depth of the ore body and economic considerations.
What are the surface and subsurface methods by which coal is commonly mined?
Surface mining methods for coal include strip mining, open-pit mining, and mountaintop removal. Subsurface mining methods involve underground mining techniques such as room and pillar mining, longwall mining, and shaft mining. Each method has its own advantages and challenges in extracting coal from the earth.
Open-pit mining is a kind of?
Open-pit mining is a type of surface mining where large quantities of material are excavated from a large, open pit. It is commonly used to extract minerals such as copper, gold, and coal.
When might miners chose to use open pit mining rather than strip mining to obtain ore?
Miners might choose to use open pit mining when the ore is found near the surface and forms a wide area, making it more cost-effective to extract using this method. Open pit mining is also preferred when the ore body is not very deep, minimizing the need for extensive excavation.
What is a method for uranium mining?
Uranium mining can be either by open pit mining or by underground mining.
The person who first introduced the idea of open-pit mining was?
Daniel Jackling introduced the idea of open-pit mining

Who invented open pit mining?
Open pit mining is a widely used mining technique developed centuries ago, and it is difficult to credit a specific individual with its invention. However, open pit mining has been practiced throughout history in various forms, with the ancient Romans known to have used similar methods for extracting minerals. The technique has evolved and is now a prevalent method in modern mining operations.

Do humans do open pit mining?
Yes. Ancient man began doing it and open pit mining continues today.

Is uranium open pit mining?
no.
Is open mining or closed mining more expensive?
Open-pit mining is generally less expensive in terms of exploration, development, equipment and operation. Typically, when a recovery operation is developed as an open-pit mine, the valuable mineral deposit is closer to the surface. Also, because it is open-pit, the scale of economy applies, meaning that larger equipment can be used, thus lowering the per-unit cost of operation. In addition, while underground mines must leave behind some of the target minerals in order to provide support for the mine structure, open-pit mines do not. It should be noted that while open-pit mining is generally the less expensive mining method. that will not always the case. This is due the geology. The nature of the ore body, and the depth and angle of the deposit will enter into cost considerations when choosing a mining method. It can also depend on the rehabilitation requirements as with open pit mining you are left with huge holes in the ground and with under ground/closed mining you simply have a small entry to close with mining is finished.
What kind of mining are open pit and quarries and example of?
Strip Mining.
