1. • • Ores of reactive metals have to be heated with carbon or carbon monoxide in order to extract the metal. Carbon is a non-metal but it is more reactive than some metals. This means that some metals can be extracted from their metal oxides using carbon. This works for zinc, iron, tin, lead and copper.

   How is a metal separated from its ore?

   • The process of separating a metal from its ore is known as smelting. Smelting is the process by which metal is extracted from its ore and has a long history dating back to the Bronze Age, when ancient peoples first learned the technique. Smelting methods range from the basic to the high-tech, and are applied to a variety of materials, including ...

   Can copper be extracted from low-grade ores?

   • Because copper is a valuable metal, it is also worth extracting it from low-grade ores as well. Ores are commonly oxides, for example: . . . or sulfides, for example: This simply means getting rid of as much of the unwanted rocky material as possible before the ore is converted into the metal.

   Can a metal be extracted from a low grade ore?

   • It is more expensive and wasteful to extract a metal from a low grade ore, but most high grade ores have already been used. In theory, any metal could be extracted from its compounds using However, large amounts of are needed to do this, so electrolysis is expensive. by heating with carbon.

   What is a metal ore?

   • An ore is any naturally-occurring source of a metal that you can economically extract the metal from. Aluminum, for example, is the most common metal in the Earth's crust, occurring in all sorts of minerals. However, it isn't economically worthwhile to extract it from most of these minerals.

   How do you extract a metal from an ore?

   • The method used to extract a given metal from its ore depends upon the reactivity of the metal and how stable the ore is. In each case the metal ions in the compound gain electrons to form atoms of the metal element. Ores of unreactive metals only need to be heated to obtain the metal.

   The process involves ore preparation, milling, and ore dressing, commonly known as beneficiation. Beneficiation mechanically separates the grains of ore minerals from the gangue (low-value) minerals that surround them in order to produce a concentrate made up of useful minerals.
