Lead Processing Plant. The lead minerals in ores are mainly galena, cerussite, and lead alum. The lead sulfide is galena, while the main lead oxide is cerussite. The lead processing technology uses flotation. There are lots kinds of lead minerals, which have flotation differences between each other. The key points in getting ideal technology
