Given the current of the cell and the duration, determine the moles of electrons produced which are used to reduce the nickel and calculate the mass of nickel that can be refined. Concept introduction: An ore is a complex mixture of metal-containing mineral and economically worthless material called Gangue, consisting of sand, clay, and other impurities. Extracting a metal from ore requires three main steps: (1) concentration of the ore, and if necessary, chemical treatment prior to reduction; (2) reduction of the mineral to the free metal; (3) refining or purification of the metal. Roasting is the process of heating the sulfide minerals in air (O 2 ) to form metal-oxides Metal-oxides will undergo reduction with carbon, hydrogen, or a more active metal. The most active metals must be reduced by the process of electrolysis . To classify: The amount of Ni that can be refined with the given current.
