Improving Zinc Recovery. During the milling process, ore is crushed and ground before proceeding to a flotation process, which separates the copper, zinc and lead. "In order to separate lead, zinc and copper from our ore, we use a series of flotation cells and different reagents to alternatively float or depress minerals," stated Brad Bunn ...
