The overwhelming majority of aluminum on earth is mined from a mineral called Bauxite. Once the aluminum is smelted out, it is no longer a mineral - it is an element: Aluminum.
Rock material mined for its constituent elements or minerals is called "ore."
Ores
Apparently alluvial diamonds migrate into placer deposits, being moved there by natural means, such as flowing water. Other materials are simply ground into tiny bits and ultimately 'placed' into the low spots in the geography. Sand is a descriptor used to name the quality of the tiny stones that make up most of the materials in placer deposits: some metal bits and alluvial diamonds are also found in placer deposits. You can read more about them, below.

Mostly coal right now. But anything can be strip mined and it's the cheapest and safest way.

A placer deposit is a type of mineral deposit that forms when valuable minerals are concentrated by the action of water, typically in riverbeds, beaches, or other sedimentary environments. These deposits occur when heavy minerals, such as gold, platinum, or gemstones, are eroded from their source rocks and transported by flowing water. As the water slows down in certain areas, the heavier minerals settle and accumulate, forming concentrated deposits. Over time, these accumulations can be mined for their valuable resources.
Placer deposits form when valuable minerals, such as gold, diamonds, or gemstones, are concentrated by the action of water, typically in riverbeds, streams, or along shorelines. These minerals are often eroded from their original host rocks and carried by sediment-laden water, where their density allows them to settle and accumulate in certain areas. Over time, these concentrated deposits can become economically viable sources for mining. Placer deposits are often mined through techniques such as panning, sluicing, or dredging.
Mica is a type of mineral that occurs as flakes, books, or sheets. It is mined. They are mined using techniques that extract mica from the metamorphic rock called schist, from placer deposits, and from pegmatites.
Nickel is the primary mineral mined in Sudbury, Ontario. Sudbury is known for its rich nickel deposits, which have been mined since the late 19th century. The region also produces other metals such as copper, cobalt, platinum, and palladium.
Chromium is primarily mined in South Africa, Kazakhstan, India, and Turkey. These countries are known for their significant chromium deposits and are major producers of the mineral.
An economic ore body, that's if you want to make a profit.
Bytownite is primarily mined in countries such as the United States, Norway, Madagascar, and Mexico. These locations are known for producing high-quality specimens of bytownite due to their geological conditions and mineral deposits.
