Advances in Flotation of Copper, Lead and Zinc Minerals
Copper, lead and zinc minerals are important non-ferrous metal resources. Flotation is a practical technique to extract minerals based on differences in physical and chemical properties on mineral surfaces. Flotation equipment, flotation techniques and flotation reagents are used for the recovery and separation of copper, lead and zinc minerals.
