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.
