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

Responsible Consumption 11th October 2013 Responsible consumption is a key concern for the 21st century as it affects individual‚ socio-economic and environmental stability on a domestic and international scale. There is overwhelming scientific evidence to suggest that global warming is a by-product of human activity. Since the industrial revolution of the 1800s‚ there has been incremental increases in global temperatures which have been reflected through the melting of the polar ice caps

Date: 9th February‚ 2011 Title: Analysis of the Elements present in Organic Compounds Aims: To test the presence of Carbon‚ Hydrogen‚ Oxygen‚ Nitrogen and Sulfur in Organic Compounds Introduction: Organic Compounds can be considered as any compound containing carbon atoms covalently bonded with other atoms‚ usually hydrogen. Other atoms may include oxygen‚ nitrogen‚ sulfur…etc. They can be found in nature‚ since “organic” means present in‚ or derived from‚ plants and animals. Materials/

Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties‚ the dichromate ion (Cr2O72–) is the specified oxidant in Methods
