Pennsylvania's most important mineral is coal. Second is oil.
A mine where mineral is produced by tunneling into the earth to the bed of mineral ore, which is then mined with underground mining equipment.
The Philippines is rich in mineral deposits such as gold, copper, nickel, chromite, and limestone. These minerals are important for the country's mining industry and contribute significantly to its economy. However, there are ongoing environmental and social issues related to mining activities in the Philippines.

Surface mining is a method in which overlying rock material is stripped away to reveal mineral deposits. This type of mining is used when the mineral deposits are close to the surface, making it easier and more cost-effective to extract them. Examples of surface mining include open-pit mining and strip mining.
what are the environmental concerns surrounding the mining of the mineral topaz
Shaft mining or strip mining.
Gregarious is not a mineral, it is the state of being friendly and outgoing. It has nothing to do with mining.
The value varies greatly depending on what type of mineral is present and what quantity of the mineral is present. Also access is important. What i would do is look at how much mines/claims are selling for in the back of a mining magazine like the International California Mining Journal and you might get some idea what it's worth.
Mining for mineral resources damages the land because they have to dig very large holes. This can kill organisms and ecosystems.

Surface mining is used when mineral deposits are close to the surface, making it more cost-effective and efficient to extract them using methods like open-pit mining. Subsurface mining is employed when mineral deposits are buried deep underground, necessitating techniques such as shaft mining or drift mining to access them. The choice between surface and subsurface mining depends on factors such as the depth and location of the mineral deposits, environmental considerations, and cost-effectiveness.
