1 in vapour state sulphur partly exists as S2 molecule which has 2 unpaired electrons in the antibondind pi orbitals jus lyk oxygen and thus exhibits paramagnetism. 2 An interhalogen compound is a molecule whose atom contains two or more different halogen atoms (fluorine‚ chlorine‚ bromine‚ iodine or astatine). Most interhalogen compounds known are binary (composed of only two distinct elements). Their formulas are generally XYn‚ where n = 1‚ 3‚ 5 or 7‚ and X is the less electronegative

means that it can be converted into both flat sheets and electrical wire. This makes silver is an ideal metal for all kinds of industrial use. Silver occurs in lead‚ Zinc and copper ore deposits. Lead ore is the main source of Silver. In fact‚ 75% of the resources in the world are found in association with other metal ores. The most important mineral is argentite‚ Sulphur Sulphide. Secondary sources are price sensitive. Secondary silver sources include coin melt‚ scrap recovery‚ and dis-hoarding from

The importance of mining is definitely significant to Canada. Mining‚ is an important industry‚ and Canadians are very advanced in their mining technology‚ but during the mining process‚ there is certain level of pollution produced. The Canadian government and the mining companies have very good plans and controls toward this problem‚ while ensuring the smooth running of the industries‚ and also helping to create strong economy and employment. The world of today could not exist without mineral products

today is called the cyanide process‚ first idealized in the 18th century by Spanish miners‚ and developed during the 19th century. Briefly‚ the cyanide process begins with crushing the silver ore into pieces‚ then the ore is stacked on impermeable pads and finally sodium cyanide and water solution is added to the ore. Most commonly‚ the Merrill-Crowe precipitation process is used to recover silver from heap leach solutions. The mining of silver has majorly increased since 3000 B.C‚ along with the preparation
