Ever wonder how and where metals like iron, copper, and tin are gotten from? You might have an idea that they are extracted from the earth crust, but does that mean that they just directly pull out metals from the earth crust, wash them clean, and here they go using it to make cars and buildings...? The answer lies in the content of minerals deposited on the earth's crust, mountains, and rocks. These minerals comes in different forms and chemical compositions, aggregated together as just one type of mineral called ores.
