Metals are primarily mined from the earth's crust, which is the outermost layer of the Earth. The crust contains a wide range of minerals and metal ores that can be extracted through mining processes. The earth's mantle, which lies beneath the crust, is composed mainly of solid rock and does not contain significant deposits of metals that are economically viable to mine.

How is granite and basalt obtained from the earths crust?
the source is found underground, and then it is mined
How are minerals extracted from the mantle?
Minerals are extracted from the mantle through processes such as volcanic eruptions, where molten rock from the mantle (magma) reaches the surface and solidifies into mineral-rich rocks. These mineral-rich rocks are then mined or quarried to extract the desired minerals. Additionally, some minerals from the mantle may be found in oceanic crust and are extracted through underwater mining operations.
Why is gold one of the few metals found as an element in earths crust?
Gold is found in its elemental form in the Earth's crust because it is unreactive with other elements, making it resistant to oxidation and corrosion. This stability allows gold to exist in its pure form without combining with other elements in the environment. Additionally, gold's high density enables it to sink deep into the Earth's crust during geological processes, where it can be mined.
Where does mining occur in the earth's structure?
Mining occurs in the Earth's crust, which is the outermost layer of the Earth. Most mineral resources that are mined for industrial purposes are found within the crust, though some mining activities may extend into the upper part of the mantle.
How do we get metals?
Metals are generally mined in the form of ore. Ore is processed to extract the metal from the ore (known as smelting)
Where is new silicon mined?
silicon is mined in near the earths crust, and it is also is made of 27.7% earths crust hope this helps
How is granite and basalt obtained from the earths crust?
the source is found underground, and then it is mined
The greatest concentration of metals occurs in earths?
The greatest concentration of metals on Earth is found in the planet's core, which is primarily made up of iron and nickel. Additionally, metal ores can be found in the Earth's crust, where they are mined for various industrial applications.
How are metals extracted from the earths crust?
Metals are extracted from the Earth's crust through processes like mining, blasting, crushing, and smelting. Ore containing the desired metal is mined, crushed to separate the metal from the rock, and then heated in a furnace to extract the metal in its pure form. Finally, the extracted metal is purified and processed for use in various applications.
What are three metals that are mined in Argentina?
Three metals that are mined in Argentina are gold, silver, and copper.
Where are metals extracted from?
Metals are extracted from various ores that are mined from underground.
The metals that they mined in the mendip hills?

What metals are found in Mt Isa?
Metals mined at Mt Isa include:coppersilverleadzinc
Why do metals reflect light?

What metals are mined?
All metals are originally mined, though some can be obtained by post-mining recycling, eg: crushing and treating old electronics to recover gold.
