coal is a valuble rock mined in Indiana
The rock is called an ore. Ores are rocks that contain minerals with high concentrations of valuable elements or metals that can be extracted and processed for commercial use.
A mineral containing a useful substance is an ore. Example: Bauxite is an ore, from which is extracted the commercially valuable metal aluminum.
Ores are mined beneath the Earth's surface because they are more concentrated and accessible in underground formations. Mining underground allows for extraction of minerals that are not easily accessible from the surface due to geological factors such as depth, topography, and the presence of rock layers. Additionally, underground mining can be more cost-effective and efficient for extracting valuable minerals in large quantities.
Granite is a type of igneous rock that is formed from the slow crystallization of magma deep within the Earth's crust. It is not an ore because it does not contain valuable minerals or metals that can be economically extracted. Ores are rocks or minerals that contain useful substances that can be mined and processed for their valuable content.
A mineral or an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined or extracted is known as ore, while the ordinary rock does not has any economical value.
Limestone is the most valuable rock mined in Indiana. It is used for various purposes, including construction, agriculture, and as a raw material for manufacturing cement and other products. Indiana limestone is particularly renowned for its durability and aesthetic appeal.
I think it might be coal I don't know for sure
Salem limestone is the official state stone of Indiana.
Limestone is one of the most common types of rock mined using a quarry. It is widely used in construction, agriculture, and as a raw material in manufacturing industries.

C. an ore. You're just googling the questions aren't you? lol
practically anywhere as it is present in high levels in most continental crustal rock.
An ore is a rock that bears minerals containing valuable elements. Most rock can be considered to be an ore although the classification is usually reserved for rock that has sufficient concentrations of elements to make it worth mining and separating.
