What are native ores?
What are native ores?
An igneous or sedimentary rock that contains a metal element in its pure state. Gold, Tin, Copper, and Platinum may be found in their metallic states in veins or alluvial deposits.
What is copper ore definition?
(geology) Any rock containing commercial amounts of copper. noun.
Why is copper found in native form?
Copper is an unreactive metal – it reacts only slowly with the atmosphere. This means that huge lumps of copper metal are found buried in the ground as nuggets. This is called native copper. Native copper isn’t mined because there is so little of it.
Where do you find native copper?
The largest copper mine is found in Utah (Bingham Canyon). Other major mines are found in Arizona, Michigan, New Mexico and Montana. In South America, Chile, the world’s largest producer, and Peru are both major producers of copper.
What is meant by native ore give example?
A native metal is one that exists in nature (on earth’s surface) in its actual metallic form. Some such native metals that we can identify as such are iron, tin, tungsten, antimony, arsenic and zinc.
Is copper a native mineral?
Native copper is an uncombined form of copper that occurs as a natural mineral. Copper is one of the few metallic elements to occur in native form, although it most commonly occurs in oxidized states and mixed with other elements….Native copper.

What is copper ore called?
chalcopyrite
The principal copper ore mineral is chalcopyrite (CuFeS2), which is commonly smelted to yield a matte containing ~50% copper.
What is copper ore used for?
Most copper mined today is used to conduct electricity – mostly as wiring. It is also an excellent conductor of heat and is used in cooking utensils, heat sinks, and heat exchangers. Large amounts are also used to make alloys such as brass (copper and zinc) and bronze (copper, tin, and zinc).
What is native copper used for?
Most copper mined today is used to conduct electricity – mostly as wiring….

What are native metals give example?
A native metal is any metal that is found in its metallic form in nature, either pure or as an alloy. Metals that can be found as native deposits singly and/or in alloys include antimony, arsenic, bismuth, cadmium, chromium, cobalt, indium, iron, nickel, selenium, tantalum, tellurium, tin, titanium, and zinc.
How are ores different from native metals?
Ore- A mineral occurring in sufficient quantity and containing enough metal to permit its recovery and extraction at a profit. Metal- An alloy of two or more metallic elements. Therefore, Rocks have minerals, which in large concentration are called ores and these are mined for metals!
