Froth Flotation Process
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.

15.1.1 Hydrothermal Vein Deposits. The copper lead-zinc vein deposits are usually characterized by coarse-grained banded to massive aggregates of pyrite, galena, sphalerite and chalcopyrite. The bulk mineralogy is quite similar to that of strata-bound sulfide deposits, except that galena tends to be much more abundant in the vein deposit.
