Froth Flotation Century Froth Flotation Chemical

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…

Flotation Froth - an overview | ScienceDirect Topics

The frother molecules are arranged at the air–water interface such that the hydrophilic or polar groups are oriented into the water phase, and the hydrophobic or non-polar hydrocarbon chain in the air phase. In fact, the frother creates conditions for froth formation. The flotation froth is a three-phase system. The frother concentrates at the interface of water and air bubbles, forming an envelope around the bubbles, which prevents them from colliding or touching. Frothers …

Flotation Froth - an overview | ScienceDirect Topics

The use of froth in flotation is twofold. First, froth is used to convey the mineral-laden bubbles from the froth–pulp interface to the concentrate launder. Second, froth is used to remove entrained hydrophilic particles by the gravity drainage of water back to the pulp (Figure 13). The froth cleaning process can be improved by spraying (wash) water upon the surface or inside the upper layer of the froth. The spraying increases the volume of water draining through the froth …
