viable for a business to mine at a particular site. However‚ due to environmental damage and global warming‚ recycling has increased globally to create a sustainable future. By examining the cost and energy expenditure of recycling and extracting aluminium we can understand why recycling is a better choice than extracting metal from its ore. Discuss the importance of predicting yield in the identification‚ mining and extraction of commercial ore deposits Yield is the amount of product obtained

strategy. In this chain Indian aluminium giant Hindalco acquired Atlanta based company Novelis Inc‚ a world leader in aluminium rolling and flat-rolled aluminium products. Hindalco Industries Ltd.‚ acquired Novelis Inc. to gain sheet mills that supply can makers and car companies. Strategically‚ the acquisition of Novelis takes Hindalco onto the global stage as the leader in downstream aluminium rolled products. The transaction makes Hindalco the world ’s largest aluminium rolling company and one of

In this booklet you learn about rusting and ways of stopping it‚ followed by a look at another metal‚ aluminium that is surprisingly resistant to corrosion. Rusting Rust is the name we give to the substance formed when iron corrodes. The same applies to most types of steel‚ as they consist mainly of iron. We all know that things tend to go rusty if they

Extraction of Aluminium Aluminium ore is called bauxite. Bauxite contains aluminium oxide‚ water‚ iron oxide and other impurities. The purified dry ore‚ called alumina‚ is aluminium oxide (Al2O3). The alumina must be molten for electrolysis to work‚ since the ions are not free to move in the solid state. Unfortunately‚ alumina has a high melting point (2040 °C) and it is not practical to do electrolysis at such a high temperature. In the middle of the nineteenth century it was found that alumina

At present‚ the raw materials to refine copper in China mainly are towanite‚ chalcocite‚ bornite‚ malachite and etc. According to the technical conditions of smelting‚ the copper ore can be divided into three classes based on the proportion of copper oxide and copper sulphide‚ that is‚ sulfide ore‚ which contains less than 10% copper oxide；oxidized ore‚ which contains more than 30% copper oxide; mixed ore‚ which contains 10%~30% copper oxide. Copper is one of earliest metals that be found and used
