Zinc processing Britannica
2 天前 Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products Zinc (Zn) is a metallic element of hexagonal closepacked (hcp) crystal structure and a density of 713 grams per cubic centimetre It has only moderate hardness and can be made ductile and easily worked at temperatures slightly above the ambient• Zinc has strong anticorrosive properties and bonds well with other metals Zinc in Construction • Zinc building products include roofing, cladding and rainwater systems • Zinccoated metal was first patented in 1837 • The process of galvanizing iron sheets, involves the ‘hotdipping’ of the sheets to protect against corrosionZinc production environmental impact 61 Process Overview 611 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do existLead and Zinc EnergyZinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth flotation methodThere are two methods of smelting zinc: the pyrometallurgical process and the hydrometallurgical process (over 90% of hydrometallurgical process is in Zinc: smelting, producing and classificationMetalpedia Table of ContentsShaft SinkingWinding Engines and EquipmentPumping Facilities at Main ShaftsCommunication between Surface and UndergroundVentilationGeneralUnderground Underground Mining Methods of Zinc Ore
Selwyn Chihong : The Selwyn Project
The Selwyn Project is a proposed zinclead mine, located in Howard’s Pass in eastern Yukon The Project is one of the largest undeveloped zinclead deposits in the world and is located 165 kilometers east of Ross River and 280 km north of Watson Lake, straddling the border with the Northwest TerritoriesMining is one of Canada’s primary industries and involves the extraction, refining, and/or processing of economically valuable rocks and minerals Mineral products – including gold, silver, iron, copper, zinc, nickel – are critical to modern industrial society Although mining has been key to Canadian settlement and development, in recent Mining The Canadian EncyclopediaEurope's largest zinc mine Tara in Ireland is Europe's largest zinc mine and also one of the largest in a global comparison Since mining began in 1977, more than 85 million tonnes of ore have been extracted Boliden acquired the mine in 2004 Thanks to exploration and acquisitions, the mineral reserve and mineral resources have grown Boliden Tara Boliden Slope Mining With fast progress of modern industry, the demand for products manufactured from metal ores has gone up literally In order to meet this demand, the awareness of uninterrupted mining, which can sharply elevate stope productivity and cut mining costs, has become a big trend in the development of mining techniques in underground minesSlope Mining, Shaft Mining, Drift Mining, Mining Mining Modern mining is an industry that involves the exploration for and removal of minerals from the earth, economically and with minimum damage to the environment Mining is important because minerals are major sources of energy [1] as well as materials such as fertilizers and steelMining Encyclopedia
