Lead Zinc Extraction Processes
Zinc and lead are the two most widely used non-ferrous metals after aluminium and copper as vital materials in everyday life. They are mined and smelted in many countries in both the developed and developing world. Both pyrometallurgical as well as hydrometallurgical methods are used for production of lead zinc depending on the type of raw material used as a charge. In the pyrometallurgical pro...
متن کاملInvestigation on life cycle assessment of lead and zinc production
Lead and zinc production is one of the main predisposing factors of excessive greenhouse gases emissions, air pollution and water consumption. In this paper, the environmental problems of lead and zinc production in Calcimin plant are expressed and life cycle assessment of this plant is assessed. The data regarding the amount of induced global warming and pollution, acidification, and depletion...
متن کاملAssessment of exposure to lead through air and biological monitoring in a lead and zinc mine
Background and aim: Lead is ubiquitous and one of the earliest metals discovered by the human. This metal is widely used in different industries due to its important physico-chemical properties like softness, high malleability, ductility, low melting point and resistance to corrosion. Lead absorbed in body with several routs and when transfer in blood is primarily in red blood cells. Human exp...
متن کاملEvaluation of Uptake and Accumulation of Heavy Metals by Lettuce in Soil Treated with Inorganic Wastes of Lead and Zinc Factories
The lead-zinc industries are known to be one of the high-risk industries in terms of the environmental issues. In this research, 15 samples of waste (cake) from Zanjan Lead and Zinc Factory were collected and six samples were selected for adding to soil according to type and concentration of heavy metals. Then, lettuce was planted in soil samples treated with different cakes. After harvesting t...
متن کاملBeneflciation Studies of Bama Oxidized Lead and Zinc Ore
Bama is one of the major concentrating plant in Iran which treats nearly 1500 tons per day sulphidic lead and zinc ore. Large amount of oxidized ore exist in Bama which has been extracted along with sulphidic ore. The main objective of the present investigation was the up-grading of the ore from Goshfil which is the major deposit in Bama. The ore contained about 16% zinc as smithsonite, about 1...
