Ores: The minerals from which a metal can be profitably extracted are called ores. Metals found at the bottom of reactivity series are least reactive and they are often found in nature in freestate; such as gold, silver, copper, etc. Copper and silver are also found in the form of sulphide and oxide ores. احصل على السعر

Unlike those of copper, iron ores are very widespread, but the extraction of iron is not so simple, because its meltingpoint is much higher (iron 1550ºC; copper 1080ºC). Any attempt to reduce (or "smelt") iron ores in a simple coppersmelting furnace will give an unusable mixture of iron and slag. احصل على السعر
