2022-05-03T22:05:25+00:00Lead Smelting an overview ScienceDirect Topics
The conventional process for smelting lead involves roasting a mixture of lead sulfide concentrate and flux on a sinter machine, followed by blast furnace smelting Environmental and energy considerations have prompted studies of a more direct route, a socalled “direct” smelting processSmelting is a key process in lead product production, and involves heating lead ore or recovered lead with chemical reducing agents Both secondary and primary smelting processes can be responsible for releasing large amounts of lead contamination into the surrounding environmentLead SmeltingA major and primary Lead mineral is galena (chemical formula = PbS) which comprises of 866% of Lead In order to smelt this mineral, a blast furnace is needed to be used A blast furnace is an enormous oven which is used to accomplish the smelting processesLead Smelting Base Metal Smelting
