What Are Ore Deposits

What is ore deposit?

An ore deposit consists of one or more ore bodies. An ore body is a mass of rock that contain ore and from which a commodity of value will be extracted.

mineral deposit aggregate of a mineral in an unusually high concentration. … A mineral deposit that is sufficiently rich to be worked at a profit is called an ore deposit and in an ore deposit the assemblage of ore minerals plus gangue is called the ore.

What is metal ore deposits?

Ore is a deposit in Earth’s crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade like copper gold and iron. Copper ore is mined for a variety of industrial uses. … Like copper gold is also mined for industry.

How ore deposits are created?

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.

Where can I find ore deposits?

They are usually found in on mountainsides and are especially plentiful near in Goron Town Southern Mine and Abandoned North Mine in the Eldin Region and Greater Hyrule. They are easily broken up with a weapon or you can use a bomb.

What is sedimentary ore deposits?

Sedimentary processes form ore either through the selective removal of nonmetallic components or by concentration of metallic minerals. Rock at the earth’s surface is subjected to weathering and leaching the process that turns rock into soil.

What is the difference between mineral deposit and ore deposit?

These valuable deposits are called ore deposits and are the subject of this lesson. Ore deposits are solid naturally occurring mineral deposits that can be extracted from the earth for an economic profit. What makes ore deposits unique is the economic benefit that can be gained by extracting these minerals.

How do you identify ores?

When identifying a mineral you must:
  1. Look at it closely on all visible sides to see how it reflects light.
  2. Test its hardness.
  3. Identify its cleavage or fracture.
  4. Name its luster.
  5. Evaluate any other physical properties necessary to determine the mineral’s identity.

What are metal deposits called?

…a profit is called an ore deposit and in an ore deposit the assemblage of ore minerals plus gangue is called the ore.

What makes a rock an ore deposit?

An ore deposit is a natural concentration of one or more minerals within the host rock.

How many ores are there?

What are some types of ore deposits?

Types of Ore Deposits
  • Komatiite-associated nickel deposits.
  • Layered mafic-ultramafic intrusion deposits.
  • Skarn deposits.
  • Fractionated granitoid-associated deposits.
  • Porphyry-associated deposits.
  • Iron oxide copper gold deposits.
  • Syn-deformational hydrothermal and replacement deposits.
  • Orogenic gold deposits.

What are four ways that ore deposits can form?

Subsurface mining (under the earths surface) Surface mining (on top the earth’s surface) Placer mining (shallow water dredging) and Undersea mining (deep sea). Name the two ways ore can be formed by Contact Metamorphism.

What is difference between ore and mineral?

Minerals are naturally occurring inorganic solids with a crystalline structure and a definite range of chemical formula. Ores are concentrations of minerals in rock that are high enough to be economically extracted for use. … You need minerals to make rocks but you don’t need rocks to make minerals.

What minerals are found in ores?

Ores are those minerals from which metal are extracted conveniently and profitably. These ores contain good percentage of metal.

How do ores occur in nature?

Metals are often extracted from the Earth by means of mining resulting in ores that are relatively rich sources of the requisite elements. … When a metal ore is an ionic compound of that metal and a non-metal the ore must usually be smelted (or heated with a reducing agent) to extract the pure metal.

What are the most valuable ores?

Why do ore deposits form in sedimentary rock?

Ore deposits form in sedimentary environments as a result of one of two generalised geological processes: either as a result of mineral precipitation from solution in surface waters most commonly from sea water or lake waters or as a result of physical accumulation of ore minerals during processes of sediment …

What are chemical deposits?

Chemical sediments form when water saturated with calcium carbonate is subjected to variations in temperature or CO2 content or gets concentrated due to evaporation thus becoming oversaturated. …

Is Ore an igneous rock?

Igneous rocks form from the solidification of molten rock called magma. These processes are thought to have formed some chromium nickel and platinum-rich layers within igneous rock but a related process forms a wider variety of ores. …

What are ores 12?
