In many cases, carbon cannot be used to reduce the metal oxide to the metal as the metal reacts with carbon to form the carbide instead. Most of the elements especially metals are present combined with other elements and these are called minerals. Each of these oxides is heated with carbon to obtain the metal. Ionic substances can be broken down into the elements they are made from by electricity, in a process called electrolysis. Your email address will not be published. Metals such as zinc, iron and copper are present in ores as their oxides. Metal ions are positively charged, so metals are produced at the negative electrode (cathode). The method that is used in the extraction of metal from its ore depends on the position of the metal in the reactivity series of metals. They are reduction of the ore with carbon, reduction of the molten ore by electrolysis, and reduction of the ore with a more reactive metal. The extraction of the metals from the calcined or roasted ore consists of two steps i.e., removal of earthy impurities and reduction of the ore to metal. Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. Sulfides are the oldest ores, formed in the Earth's history when there was a lot of sulfur from volcanic activity.
