Minerals are typically organized by their chemistry, into groups like the carbonates, silicates, sulfides, etc. They can also be organized by various other properties, like hardness, density, crystal system, etc.
It is so because metals cannot be extracted from minerals in a convenient way. E.g.:- Aluminum metal is found in both minerals: clay and bauxite. Aluminum metal is extracted only from bauxite in a convenient way. So, bauxite is an ore of aluminum. On the other hand, it is not extracted from clay so clay remains only as mineral not ore of aluminum.
Rock material mined for its constituent elements or minerals is called "ore."
Yes it is. Hornblende under chain silicates group. Diagram below shows which group and sub-groups it belongs to:CHAIN SILICATES1. Pyroxenes2. AmphibolesHornblende (is here)OxyhornblendeEtc.3. Pyroxenoids4. Other Chain Silicates
Minerals found next to each other are called adjacent.
feldspar
Bauxite is the main source of aluminum. Albite is a feldspar mineral and is a sodium aluminum silicate All rocks contain other minerals.
Silicates
Minerals containing silicon and oxygen are most generally known as silicates.
The real question is what type of rock doesn't contain aluminum sillicates and other mineralsBut if you really want the answer I suppose I will tell you. It's feldspar. Happy?
Rock-forming minerals 1. Silicates - are minerals which consist of silicon and oxygen with some metals or nonmetals. Some rocks which have these minerals are granite, sandstone, basalt, gneiss and quartzite. 2. Carbonates - are minerals which consist of carbon, oxygen and some other elements. Rocks in which these minerals are found include marble, limestone and dolomite. 3. Oxides - are minerals which consist of oxygen and some other elements. They are found in rocks such as sandstone and shale. Although there are about 3000 different minerals found on Earth, there are only very few of them which form rocks.
They are classified as silicates, one of the more common being the mineral quartz which is composed only of the elements silicon and oxygen (SiO2). Other silicate minerals may include one or more other elements as well in their chemical formula.
It is the absolute silicate. All other silicates have greater amounts of silicon and oxygen along with other minerals.
Clays are hydrous aluminum silicates with trace amounts of other elements like calcium, iron, and magnesium.
Isolated tetrahedra silicates do not link with other silicon or oxygen atoms Ring Silicates form by sharing oxygen atoms Single Chain Silicates form a chain when sharing oxygen atoms Double Chain Silicates form when two or more single chains of tetrahedra bond to each other Sheet Silicates form when each tetrahedron shares three of its oxygen atoms with other tetrahedra Framework Silicates form when each tetrahedron is bonded to four other tetrahedras :)
Aluminum extrusions are used to turn aluminum alloy into other materials for cross sectional profiles. It is extracted from other metals containing aluminum and squeezed out.
They are made of the same material as asteroids and meteorites, namely water, silicates, oxides, sulfides, and a few other minerals.
