(ii) Stages involved in the extraction of metals. (a) Dressing of the ore – hydrolytic method, magnetic separation, froth flotation method. (b) Conversion of concentrated ore to its oxide- roasting and calcination (definition, examples with equations). (c) Reduction of metallic oxides- some can be reduced by hydrogen, carbon and carbon monoxide (e.g. copper oxide, lead (II) oxide, iron (III) oxide and zinc oxide) and some cannot (e.g. Al2O3, MgO) - refer to activity series). Active metals by electrolysis e.g. sodium, potassium and calcium. (reference only). Equations with conditions should be given. (d) Electro refining – reference only. (iii) Extraction of Aluminium. (a) Chemical method for purifying bauxite by using NaOH – Baeyer’s Process. (b) Electrolytic extraction – Hall Heroult’s process: Structure of electrolytic cell - the various components as part of the electrolyte, electrodes and electrode reactions. Description of the changes occurring, purpose of the substances used and the main reactions with their equations. (iv) Alloys – composition and uses. Stainless steel, duralumin, brass, bronze, fuse metal / solder.
