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.
When there is enough of a metal or a metal compound in a rock to make it worth extracting
A metallic ore contain a significant concentration of a metal.
No, metal ores occur naturally in the Earth.
Metal ores are refined into metal. Metal is very useful, hence, metal ore is also useful.
Those ores which contain metal in the form of oxides are called as oxide ores.
no
Carbon, usually in impure form such as coal or coke, is often used to remove oxygen from metal ores.
No, metal ores occur naturally in the Earth.
Metal ores are used as resources from which metals may be extracted.
Metal ores are refined into metal. Metal is very useful, hence, metal ore is also useful.
Factories do not make metal ore. A refinery or smelter makes metal from metal ores.
From various minerals and ores which are mined. Which metal depends on which mineral is mined.
Those ores which contain metal in the form of oxides are called as oxide ores.
no
Yes and No, while some metal ores may indeed be vein minerals, not all vein minerals are metal ores and not all metal ores are vein minerals.
They aren't considered to be ores because ores are partly mineral and partly metal. The metal deposits are purely metal.

Carbon, usually in impure form such as coal or coke, is often used to remove oxygen from metal ores.
Metal ores are metallic elements found in compounds with other elements in nature. These ores are then separated to produce pure metals.
