Name a metal that could be extracted from its metal oxide by heating with carbon. answer choices. WebFirst, the concentrated zinc blende is converted to its oxide (by roasting). After this, the oxide is reduced to zinc metal. The reactions for the two processes are: 1. Roasting: Zinc blende is subjected to roasting, i.e. it is heated in the presence of excess air. This converts zinc sulphide ore to zinc oxide. The reaction involved is:
WebThese metals are obtained by electrolytic reduction. For example, sodium, magnesium, and calcium are obtained by the electrolysis of their molten chlorides. The metals are deposited at the cathode (the negatively charged electrode), whereas, chlorine is liberated at the anode (the positively charged electrode). The reactions are WebAluminium is extracted from its ore, bauxite, by electrolysis. Bauxite is an impure form of aluminium oxide, Al 2 O 3. (a) Describe how aluminium is extracted from bauxite.
