3.0 INTRODUCTION Recently‚ University Putra Malaysia (UPM) have involved in a project that focuses on the environmental awareness. This project is called “Bandar Hijau Serdeng”‚ collaboration between UPM with the Subang Jaya Municipal Council (MPSJ0 which involved in activities from simple “3R’’ proses which includes reduce‚ recycle and reused campaigns. Extension to this project‚ UPM has decided to build a pavilion for the purpose of providing a place to sit and enjoy the scenery of Serdang town

Galvanic Corrosion in the Statue of Liberty Introduction: The Statue of liberty built by Gustav Eiffel and Frederic Bartholdi in 1886 was made of materials that consisted of a wrought iron framework with an outer cladding of copper attached by saddles of copper. It was pretty much anticipated that galvanic corrosion would occur so both of the metals were separated by an insulation known as “asbestos and shellac” insulation (Shellac is a natural resin that was widely used in the Victorian

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

Describe the extraction processes‚ including chemical equations‚ of copper and aluminium and describe the environmental impact of these extraction processes. Copper There are two main methods used to extract copper from its ores. Generally‚ copper is extracted using the Pyrometallurgical method (also known as smelting)‚ which allows

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

of aluminium over the past six years. It can be seen from Figure 1 that the price of aluminium has fluctuated a great deal during this period. For example: between July 2008 and February 2009 the price fell by 57%; in August 2009 alone the price rose by 16%. In an essay of 1500 words or fewer‚ use economic analysis to explain changes in the price of aluminium over the period shown in Figure 1 and why the price fluctuations have been so great.
