Extracting iron from its ore Chemical reduction with carbon
Iron from the blast furnace is very brittle because it contains up to 4.5% carbon. Most of this iron is converted to steel, which is far more useful, by removing most of the carbon. Mild steel contains approximately 0.5% carbon.

Extraction of metals Only some unreactive metals such as silver, gold and platinum can occur freely in nature. Most metals react with other elements to form ores. Major steps in extraction of metal • Ore concentration • Ore is purified and concentrated, unwanted rocks removed • Reduction to crude metal • Metal oxides to be reduced to metals, resulting in …

Extraction of Metals | PDF
Extraction of Metals - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. Metals are extracted from their ores found in the Earth's crust. Iron is extracted through a blast furnace process where iron ore, coke and limestone are heated together. Carbon monoxide reduces the iron oxide to iron which melts and runs to …

Refined iron • Refined iron: To use grey pig iron, a preliminary refining process was necessary to remove silicon. The pig iron was melted in a running out furnace and then run out into a trough. 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.

12. Electrolysis is the passing of a direct electric current through an ionic substance that is either molten or dissolved in a suitable solvent, producing chemical reactions at the electrodes and separation of materials. The main components required to achieve electrolysis are: An electrolyte: a substance, frequently an ion-conducting polymer that contains free ions, …

Blast furnace | PPT
Air is blasted into the bottom to fuel reactions that melt the iron out of the sinter. 2. Molten iron collects at the bottom of the furnace and is tapped out periodically. Slag floats on top and is also tapped out. Wasted gases exit from the top. 3. The iron produced contains carbon and impurities, making it cast iron.

Solvent extraction of iron (III) from aqueous hydrochloric and sulphuric acid solutions was carried out using Tri butyl phosphine oxide [TBPO] in chloroform as extractant. Stripping of iron (III) from the organic phase was attempted with 2.0M NaOH. Extractions were nearly quantitative with both the acid solutions. Based on the results obtained, estimation of …
