2005-1-1 · Froth flotation of plastics3.1. BackgroundAlthough froth flotation is a long-established unit operation in minerals dressing (more than a century), its application to plastics mixtures is not noted in early treatises on waste plastics recovery, such as Hegberg et al. (1992), Leidner (1981) and Yen (1974).

Froth flotation was then examined for the separation of values from the cyclone underflow. Various depressants and surface modifying agents were assessed for both direct and reverse flotation separations. ... Waste clay, long known as an ultimate processing challenge in the industry, is now considered a precious reserve for P and other critical ...

2020-1-28 · Experimental results demonstrated that the flotation method was very successful in diminishing much of the waste fraction. A froth product, with more than 280 g/t Au and 2800 g/t Ag, was produced from a feed containing 174 g/t Au and 1834 g/t Ag with approximately 87% Au and 82% Ag recoveries.

2016-11-22 · The use of froth flotation techniques to process waste products from atomic reactors and fuel processing wastes is growing in importance. The application of the flotation process to an atomic waste problem was reported in 1957. A uranium fuel rod ruptured and scattered radioactive flakes of material in a “room- size” heavy water container.
