The theoretical grade-recovery curve for an ore is a definition of the maximum expected recovery by flotation of a mineral or element at a given grade. This is defined by the surface area liberation of the value minerals and is consequently directly related to the grind size utilised in the process. The theoretical grade-recovery can be readily used to quickly identify potential recovery

2. Definition of flotation The process of seperation of mixed liberated particles from each other if there are sufficent differences in their wettability is called flotation. 3. Principle Of Operation Froth flotation commences by comminution (that is, crushing and grinding), which is used to increase the surface area of the ore for subsequent

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.
