No, metal ores occur naturally in the Earth.
They aren't considered to be ores because ores are partly mineral and partly metal. The metal deposits are purely metal.
Metal ores are refined into metal. Metal is very useful, hence, metal ore is also useful.
Metal ores are used as resources from which metals may be extracted.
Factories do not make metal ore. A refinery or smelter makes metal from metal ores.
Metal ores are rocks which contain useful metals economically convenient to exploit.
No metal deposits in Antarctica are not consitered ores because they are not profitable.
because metals are contained in the ores
Those ores which contain metal in the form of oxides are called as oxide ores.
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.
By chemical processing of lead ores (or complex metal ores).
Metal ores are rocks with metal in them. The ore can be extracted in a furnace by heating the ore, coke and limestone at a very high temperature. The molten metal is then collected off.
Mined of metal ores depend on the position of the metal in electrochemical or activity series but metals can be extract through electrolysis and reduction process.
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.
A primary metal is obtained directly from ores.
all metal extraction is done from ores
gold is usually found in cinnabar ores because it is unreactive
Beneath the surface
In the ground.
Ores are aggregates of minerals from which a valuable constituent, especially a metal, can be profitably mined or extracted.
