Galena, or lead sulfide, the world's major source of lead ore, occurs worldwide; and, it is mined in many countries, including the United States, Australia and China. Lead ore comes from underground mining operations, where the lead ore seams are blasted out of the ground and transported to the surface for refinement.
Galena flotation and galena separation from pyrite were strongly dependent on the metal oxidation species produced on galena and pyrite surfaces under different grinding conditions. Iron oxidation species depressed both galena and pyrite flotation, while lead oxidation species activated pyrite but had little effect on galena.
The most important lead ore is galena (lead sulfide). Other important ores such as cerrusite (lead carbonate) and anglesite (lead sulfate) may be regarded as weathered products of galena and they are usually found nearer to the surface. Lead and zinc ores often occur together and for most extraction methods they have to be separated.
