Jan 30, 2015 . History Introduction Basic Principles Mechanics of Flotation Chemicals of Flotation Advantages and Disadvantages References 2; 3. HISTORY 1869 - WILLIAM HAYNES patented a process of separation of minerals and gangue using oil, which he called “Bulk Flotation”. 1896-97 - FRANK.

Froth flotation - Wikipedia

Later writers have pointed to Haynes's as the first "bulk oil flotation" patent, though there is no evidence of its ever being field tested, let alone used commercially. While in 1877 the brothers Bessel (Adolph and August) of Dresden, Germany, introduced their commercially successful oil and froth flotation process for extracting.

Flotation works by the fact that water repellent particles readily attach themselves to air bubbles, and the bubbles tend to adhere to them, lifting them to the surface of the froth. The more wettable minerals—like those having a vitreous luster such as calcite, quartz and other silicates—have a fully wet surface that prevents the.
