Froth flotation - Wikipedia

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 work-place applications, especially at Broken Hill, Australia, that brought the technological innovation known as “froth flotation.” During the early 20th century, it dramatically revoluti…
