Descriptions of the use of a flotation process have been found in ancient Greek and Persian literature suggesting its antiquity. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven workplace applications, especially at Broken Hill, Australia, that brought the technological innovation known as froth flotation. During the early 20th century, it dramatically revoluti
