Lead Smelting WorstPolluted

Lead processing either requires the mining of new, primary lead, or the recycling of used products and scrap metals. Both forms of lead must be melted using a smelting process in order to obtain pure and usable forms of the metal. The primary smelting process involves separating lead from ore using heat and reducing or purifying agents such as coke and charcoal. Once the lead ore is mined, it

Impacts of Smelting Base Metal Smelting

Smelting is known to be a major cause of pollution in the environment. When smelting occurs, along with the metal produced, a solid waste product, called stag, is also produced [1]. This slag is emitted into the air and can be a cause of the pollution although not a major one. The majority of the pollution is caused by air emissions [1]. The smelting of sulfide ores (such as Lead (II)
