LEAD ZINC EXTRACTION PROCESSES

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.
