Froth Flotation Process - Detailed Explanation With Diagrams ... - BYJUS

Such ores containing multiple metals such as lead, copper and zinc can be selectively extracted by using froth floatation. The minerals that do not float into the froth are called the flotation tailings or flotation tails. The froth flotation process was first patented by H. F. K. Pickard, E. L.Sulman and John Ballot in the year 1906.

Zinc - Wikipedia

In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn 2+ and Mg 2+ ions are of similar size. [note 1] Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral.
