lead zinc ore flotation Xinhai

2021-8-20  The common lead-zinc sulfide ore in nature is mainly a lead-zinc sulfide poly-metallic ore, often accompanied by a variety of valuable components, such as lead, zinc, copper, sulfur, and other useful minerals. Due to the difference in floatability of different minerals, the lead-zinc ore flotation process of mineral beneficiation is also different.
