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…

Effects of Process Parameters on Selective Flotation of ...

Selective flotation of lead-zinc ore depends on a number of parameters like particle size distribution of the feed, collector, frother, depressant, activator, pH of the pulp, regrinding and multi-stage cleaning- of the rougher concentrates etc.While designing the process flow-sheet for a given ore sample it is necessary to examine the effects of different variables on the process performance (Pradip, Das and Singh 1995).
