Smelting in Tasmania Zinifex Zinc Smelter Zinc is the metal produced at the Zinifex Zinc Smelter, it is an electrolytic plant, the amount of Zinc metal made at Zinifex Zinc Smelter annually is over 250,000 tonnes, and the base ore required for the production of Zinc metal is Zinc Sulfide found in the earth’s crust. The formula for Zinc Sulfide is ZnS, Zinc Sulfide is required to be concentrated to be smelted, as when the ore is mined it rarely is rich, due to the ore mined only contains 5-15% Zinc

Copper is an inexpensive metal that transpires in abundance in communities where copper mining occurs, such as Queenstown, Tasmania. Copper resists corrosion and an effective conductor of heat and electricity, which makes it an ideal material. However, copper mining is a factor that influences acid rain on a large scale through the use and release of a variety of detrimental chemicals. One positive impact of copper mining is that it has a great impact on the economy, as it is a multi-purpose metal

Sypnopsis In this experiment, acetylsalicylic acid was synthesized from the acidification of salicylic acid and acetic anhydride. The objective was to convert a specific amount of salicylic acid into the same amount of aspirin that was high in purity. Furthermore, the other objectives were to enable students to conduct the synthesis of aspirin, reinforce skills or recrystallisation and the technique of melting point determination. The amount of each compound should be the same because there is

A burden which lays on the shoulders of today’s man is that of climate change, namely, global warming. However, this evil has many ignored byproducts, some which are equally detrimental. In this thesis, we will write about the effects of one of the greatest of this, ocean acidification, known as “global warming’s equally evil twin”. When scientists first discovered ocean acidification, they thought that it might be a good thing for mankind, a helping hand in the war against excess carbon dioxide

Another consequence of using Acid rain is rain that contains high levels of nitric and sulphuric acids, which are the result of burning fossil fuels because when sulphur dioxide and nitrogen oxides are released into the air as byproducts of burning fossil fuels, the SO2 and NO react with water, oxygen and other chemicals to form sulphuric and nitric acids. These then mix with water and other materials before falling to the ground. This rain can be harmful to plant and animal life. For example The

Preparation of Standard Volumetric Solutions 1. 0.1N Sodium thiosulphate solution Reagents: Sodium thiosulphate crystals, Potassium dichromate (primary standard NIST certified), Sulphuric acid, Potassium iodide , Starch Solution (1%): Weigh 1g of soluble starch and mix it with 100ml of boiled water. Procedure • Weigh 25 g of sodium thiosulphate crystals and transfer it in a 1000 ml volumetric flask. • Dissolve it in minimum amount of distilled water and make up the volume to 1000 ml. Standardization

The results obtained in this experiment were better than expected. Throughout the duration of this experiment some difficulties were faced. The main difficulty encountered was the lack of crystals forming when the Aminophenol/Acetic Anhydride mixture was put in the ice bath. This resulted in the experiment needing to be repeated a further 3 times before any crystals formed. The percentage yield of 64.07% is a moderate yield and was better than expected considering the problems that were encounters

The Outbreak: At the outbreak of the war, most women still found themselves in their homes doing nothing new other than the usual house chores while others such as the suffragettes were campaigning for change. This however all changed when the men headed abroad to fight, women found themselves taking over the men’s roles in factories, shops, and offices across the country. Supporting the home front: Between 1914 and 1918, more than a million women joined the workforce to fill the gap left by the
