Ore 1 of 20 The list of elements in order of the reactivity. The most recative element is put at the top of the list. Reactivity Series 2 of 20 A reaction in which oxygen is removed (or electrons are gained). Reduction 3 of 20 The breakdown of substace containing ions by electricity. Electrolysis 4 of 20 The huge reaction vessels used in industry to extract iron from its ore. Blast Furnace 5 of 20 The impure iron taken directly from a blast furnace. Cast Iron 6 of 20 A mixture of metals (and sometimes non-metals). Alloy 7 of 20 An alloy of iron with small amounts of carbon or other metals, such as nickel and chromium, added. Steel 8 of 20 Alloy of iron containing controlled, small amounts of carbon. Carbon Steel 9 of 20 Alloy of iron containing small amounts (1 to 5 percent) of other metals. Low-alloy steel 10 of 20 Expensive alloy of iron mixed with relatively large proportions of other metals. High-alloy Steel 11 of 20 A chromium-nickel alloy of steel which does not rust. Stainless Steel 12 of 20 A low density, corrosion resistant metal used in many alloys, including those used in the aircraft industry. Aluminium 13 of 20 A shiny, corrosion-resistant metal used to make alloys. Titanium 14 of 20 Rock that contains a high proportion of a copper compound. Copper-rich Ores 15 of 20 Heating a metal ore in order to extract its metal. Smelting 16 of 20 Process of extraction of metals from ores using microorganisms. Bioleaching 17 of 20 When one element takes the place of another in a compound. Displace 18 of 20 The process of extraction of metals from ores using pants. Phytomining 19 of 20 Elements in the central block of the periodic table. It has typical metal properties and forms a coloured compound. Transition elements 20 of 20
