No, they are often very impure, hence the lengthy and expensive refining processes for most.

What are metal oars?
Metal ores are metallic elements found in compounds with other elements in nature. These ores are then separated to produce pure metals.
What are the Fairly reactive metals found as ores compounds often oxides and carbonates and can be extracted using carbon to reduce the metal compound to the pure metal?

What is metal ores?
Metallic ores are rocks that contain metals.Sometimes it contains a metal compound, like Hematite, an ore of Iron, Fe2O3, for example. They can also contain metals that are found in their pure form, like copper (which can form compounds, but not usually when found in ore) and Gold (which does not form compounds). This is known as a 'native' metal.
Which metals are not found in ores?
There are a lot more than five. For example, all the alkali and alkaline earth metals are not found naturally in pure form but occur only in compounds. It's actually unusual for a metal to exist in pure form in nature; most of them occur only in compounds.
Fairly reactive metals found as ores?
no because if the metals were reactive then they would react with elements in the air non reactive metals are found in there native state like gold and silver.
Which type of principals are involved in extraction of the element?
Extraction of pure metal from ores. That's all on my side.
A mineral that contains a large amount of one or more metal compounds is called?
Minerals from which metals and nonmetals can be removed in usable amounts are called ores.
What is a rock that contains metal or a useful mineral?
A rock containing a useful substance is called an ore. It's important to recognise that whilst a few ores contain metals (e.g. gold), most things referred to as metal ores actually contain metal compounds.
Is an metal acidic or alkaline?
Pure metals are neither, no pure element is and acid or an alkali, it is only compounds made from elements that have this property. When metals form compounds those compounds are typically alkaline.
Are metal ores synthetic?
No, metal ores occur naturally in the Earth.
What are some common compounds of aluminum?
Aluminum is an element (pure metal), not a compound.
Why can gold be dug out of underground but not aluminium?
Gold is an unreactive metal and can be found in the pure metallic form.Aluminum is a very reactive metal and can only be found combined with other elements as aluminum ores. These ores are readily mined both underground and in open pits.
