Elemental mineral
Aluminum is considered a trace mineral. Trace amounts of aluminum are commonly found in foods, but it is harmless in the natural form when eaten in moderation. Elemental aluminum can be toxic.
Bauxite is a type of ore that is a principal source of aluminum. It is not a mineral group, but rather a mineral itself composed mainly of aluminum hydroxides, iron oxide, silicon dioxide, and clay minerals. It is formed through the weathering of aluminum-rich rocks.
Bauxite is not a mineral, and therefore does not belong in any mineral group. Bauxite is a form of consolidated, extremely weathered soil that is high in aluminum content, and the main ore of aluminum.
Rubies are part of the corundum mineral group.
Sapphire comes from the corundum mineral family, which is an aluminum oxide (Al2O3). Corundum consists of pure aluminum oxide, it also contains trace amounts of other elements such as iron, titanium and chromium.
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.
No, sapphire is not a silicate. Sapphire is a variety of the mineral corundum, which is composed of aluminum oxide (Al2O3). Silicates are minerals that contain silicon and oxygen as their main components, such as quartz and feldspar. Sapphire belongs to the oxide mineral group, not the silicate group.
The most common mineral group is the silicate mineral group, which is characterized by minerals containing silicon and oxygen, often combined with other elements such as aluminum, iron, calcium, or magnesium. Examples of silicate minerals include quartz, feldspar, and mica.
It is a metallic mineral.
The most common mineral group is the silicate mineral group, which includes minerals such as quartz, feldspar, and mica. Silicate minerals are composed primarily of silicon and oxygen atoms, along with other elements like aluminum, potassium, or iron. They make up over 90% of the Earth's crust.
The most common mineral group in Earth's crust is the silicate mineral group. Silicates are composed of silicon and oxygen atoms, along with other elements like aluminum, iron, magnesium, and calcium. They make up about 90% of the Earth's crust.
