   How can metals be extracted from ores?

   • Metals can be extracted from ores by reduction – the removal of oxygen or forming a metal element from a compound. Oxidation and reduction have multiple meanings, not just to do with the addition and removal of oxygen. Encourage students to use key terms as often as possible.

   Which ores are processed to extract metals from waste rock?

   • The ores must be processed to extract the metals of interest from the waste rock and from the ore minerals. Figure 12.3.1 12.3. 1: Three Common Ores. (left) Iron ore, (middle) Manganese ore – psilomelane, and (right) Lead ore – galena and anglesite. An alloy is a mixture composed of two or more elements, at least one of which is a metal.

   What is a metal extraction process?

   • For highly reactive metals like sodium, calcium, aluminium, and potassium, extraction of metal from the ore involves electrochemical methods. This process is termed as electrolysis. The process of electrolysis involves passing an electric current through an ionic substance that is either molten or in solution.

   What are the extraction methods used for different metals?

   • The table summarises the extraction methods used for different metals. Although an unreactive metal is found as an uncombined element, chemical reactions are often needed to remove other elements that might contaminate it. Zinc mostly occurs as sulfide ores, which are heated in air to convert them to zinc oxide.

   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.

    Metals like copper, zinc, or lead, which are moderately reactive, can be extracted from their ores by heating them with carbon or carbon monoxide. This is known as reduction with carbon. For highly reactive metals like sodium, calcium, aluminium, and potassium, extraction of metal from the ore involves electrochemical methods.
