Is ore a mineral?
Ores are usually used to extract metals economically. … All ores are minerals. Minerals are native forms in which metals exist. Ores are mineral deposits.
What is an ore body?
Generally, an ore body is an accumulation of a solid and fairly continuous mass of ore with gangue, distinctly distinguishable by form and character from the enclosing host rocks. … The sheet, the most common shape in which sedimentary deposits occur, is a tabular body separated from other rocks by bedding planes.
How do you identify ore?
- Hardness. The ability to resist being scratched—or hardness—is one of the most useful properties for identifying minerals. …
- Luster. Luster is how a mineral reflects light. …

- Specific Gravity.
How ore is formed?
Deposits of minerals form when a medium that contains and transports mineral-making ore releases and deposits the ore. … When magma or lava cools, the magma and ore carried within it crystallize to form tiny minerals in the newly-created igneous rock. Minerals found in such rock might include feldspar or mica.

Is iron an ore?
Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Iron ore is the source of primary iron for the world’s iron and steel industries.

What is an ore for Class 8?
Answer: A rock from which a particular mineral can be profitably extracted is called an ore. The ores of metallic minerals are generally located in igneous and metamorphic rocks.
What is an ore answer?
Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals.
What is an ore Class 7?
An ore is a mixture of many minerals or an accumulation of minerals mixed with other elements. The ore must have minerals in sufficient quantity for it to be commercially extracted. Example of an ore is bauxite. Bauxite is the ore of aluminium. Ores are often mined, smelted and treated to extract the mineral.

What is a gold ore?
Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold per ton of rock.

Why Every mineral is not an ore?
A mineral is a naturally occurring inorganic solid with definite chemical composition and a crystalline structure. … All ores are minerals, and metals can be extracted commercially. But all minerals are not ores because some of the minerals have unwanted substances.
What are the characteristics of rocks?
Rocks are classified according to characteristics such as mineral and chemical composition, permeability, texture of the constituent particles, and particle size. These physical properties are the result of the processes that formed the rocks.
What is the most common metal ore?
Most Common Metal Ores
Aluminum is one of the most common elements in the Earth’s crust and is found in a variety of silicate ores, which are often a type of clay. As the minerals become weathered they are broken down into hydrated aluminum oxide, which is known as bauxite.
What is ore deposition?
An ore deposit, in its simplest terms, is a portion of the Earth’s crust from which some industrial raw material can be extracted at a profit. As such, its characteristics are as much economic as geochemical.
What are ore forming minerals?
An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically. The formation of the ore process is called the genesis of the ore. …
