Almost all minerals consist of mixtures of compounds. A compound is a molecule or polyatomic structure containing more than one element; a mixture contains more than one type of molecule. Both must contain more than one atom, so they are not pure elements. Most minerals are in fact oxides, such as silica (silicon dioxide) or alumina (aluminium oxide).
What else can I help you with?
What is the difference in composition between most minerals and a pure element?
elements sounds cooler by Ralph gacad
The mineral family that includes the most common and most abundant minerals smooth cleavage surfaces aid in identification?
The most common mineral group contains silicate minerals.
What is the most common mineral in the composition of minerals?
Oxygen.
What composes rock?
A mineral, or in most cases, a combination of minerals.
Which minerals are non renewable?
the most norenewable mineral is coal
The most common mineral group contains what kind of minerals?
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.
The mineral family that includes the most common and most abundant minerals?
feldspar
Is a mineral an ore?
Not necessarily. An ore is a mineral deposit that contains some resource that can be extracted profitably. So while ores are minerals, most minerals are not ores.
The most common mineral group contains minerals?
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.
Which of the mineral groups is most abundant in the crust?
Quartz is the most abundant single mineral. Feldspars are, as a group, the most abundant minerals. Quartz and feldspars are classified as silicate minerals, the classification of mineral with the most abundance in the Earth's crust.
What are the most useful physical properties of minerals?
Some of the most useful physical properties of minerals include hardness (measured on the Mohs scale), cleavage and fracture (how a mineral breaks), color, streak (color of mineral powder), luster (appearance of a mineral's surface), and crystal habit (the shape in which a mineral naturally occurs). These properties help identify and classify minerals.
What are two main reasons to mine for minerals?
Most mineral ores are under the surface. Mining minerals can be profitable.
