many protective paints and sealants don’t defend against rust. Salt water penetrates the protective layers to corrode the metal. Corrosion in iron Rust on iron is produced in sea water when iron (Fe) comes in contact with oxygen. The reason for this is because when water interacts with iron it conducts a small amount of current that flows through the iron. Salt increases the amount of ions in water allowing it to become a better conductor. The full chemical equation for this process theoretically

aluminium. Iron is the second most common metal in the world and cheaper to extract than aluminium. It is extracted by using a blast furnace. Iron ores such as haematite contain iron oxide‚ the oxygen must be removed which then leaves the iron behind. This reaction is called a reduction reaction. Carbon is more reactiuve than iron so it can displace the iron and join with the oxide 2Fe2O3 + 3C → 4Fe + 3CO2 Above you can see the iron oxide has been separated into iron and carbon dioxide

copper sulfate (blue crystals)‚ sodium chloride (salt)‚ and iron. Copper sulfate is a chemical compound which is produced commercially by reacting various copper (II) compounds with sulfuric acid [1]. It generally appears as a bright blue or green crystal [1]. Its chemical formula is CuSo4. Iron is silver-white magnetic metallic and readily rusts in moist air [3]. Its chemical formula is Fe. The chemical reaction was demonstrated by the iron reacting to the copper sulfate.

Port Kembla Steelworks has spent $18 million on upgraded sinter machines that reduce the amount of coke need for the sintering process. The sintering process being getting the small particle of iron that were too small to go through processing and putting them through 1100-1300oC heat they will coalesce and form larger particles which improves resource efficiency. The upgrade involve using natural gas rather than coke to generate the heat in the

Hypothesis: Rust is a reddish or yellowish-brown flaky coating of iron oxide that is formed on iron or steel by oxidation‚ especially in the presence of moisture. The rusting process is electrochemical‚ meaning it forms from a chemical reaction which takes place in a solution where there is an electron transfer between the electrode and the electrolyte or species in solution. In the case of rusting‚ the transfer of electrons from iron to oxygen begins the electrochemical process. Electrolytes accelerate

Extractive Metallurgy Minerals are naturally occurring chemical substances in the earth’s crust obtainable by mining. Out of many minerals in which a metal may be found‚ only a few are viable to be used as sources of that metal. Such minerals are known as ores. Examples: Galena‚ PbS‚ etc. It is usually contaminated with earthly or undesired materials known as gangue. The extraction and isolation of metals from ores involve the following major steps: • Concentration of the ore‚ • Isolation of the
