Process Mineralogy Characteristics and Flotation …
Zinc and lead enjoy tremendous importance owing to their wide application in in-dustries. In the past few decades, more than eighty percent of zinc and lead originated from sulfide minerals (e.g., sphalerite, galena) because of their good hydrophobicity. With the fast consumption of zinc lead sulfide ores, the beneficiation of oxidized lead and ...
