Lead. A. Mohamad Ghazi, James R. Millette, in Environmental Forensics, 1964. 4.3.2 Mining and Production of Lead. Lead and zinc ores often occur together, and there are a large number of countries that mine and process lead ore, making it among the most widespread metals in terms of primary production (Kesler, 1994).Most of lead mining is done by highly mechanized …

6.1.2.3 Lead Ore Processing Lead ore beneficiating includes milling, concentration, and sintering. After sintering, the ore is smelted in a blast furnace to produce rough lead bullion. Rough lead bullion still contains many impurities. Therefore, the rough lead bullion is refined to remove and recover other metals.

The impurity sulfur in lead–zinc-bearing hematite–limonite ore mainly exists in the form of galena, sphalerite, pyrite, and natural sulfur, and deep reduction roasting–low intensity magnetic separation does not effectively remove sulfur in a low valence state, which affects the quality of iron ore concentrate. Thereby, the desulfurization mechanism of the oxidative …
