2015-9-10Iron ions as a catalyst in the reaction between persulphate ions and iodide ions. The reaction between persulphate ions peroxodisulphate ions S 2 O 8 2- and iodide ions in solution can be catalysed using either ironII or ironIII ions. The overall equation for the reaction is For the sake of argument well take the catalyst to be iron

This process oxidised the silicon to form a slag which floated on the iron and was removed by lowering a dam at the end of the trough The product of this process was a white metal known as finers metal or refined iron Precious metals Precious metal refining is the separation of precious metals from noble-metalliferous materials
Mild steel consists of iron alloyed with less than 0.3 percent carbon most commonly between 0.1 to 0.25 percent. The building industry frequently uses mild steel in construction because of its ductility and malleability. Girders nuts bolts and screws often consist of mild steel according to the UK Technology Education Centre
Conversion factor iron ore steel The steel flux and iron melts in the oven and impurities are driven off resulting in liquid steel. Higher quality coke results in higher quality steel. Another well-known process of steel making is completed with an electric arc furnace. Unlike a blast furnace an electric arc furnace uses no iron in steel making

Wrought iron is almost pure iron with around 0.02- 0.03 carbon whereas steel contains 0.15-0.25 of carbon.Wrought iron is a ductile material and resistant to corrosion whereas steel has more strength due to the more percent of carbon in it
2020-5-9Steel an alloy of iron and carbon can also be protected by mixing in other metals e.g. chromium to make nonrusting steel alloys called stainless steels. The chromium like aluminium forms a protective oxide layer. Coating iron or steel with a thin ZINC layer is called galvanising. Typical examples are steel buckets steel nails and
