·The application of flotation on a reasonable scale within the gold mining industry commenced in the early 1930s following the introduction of water soluble flotation collectors specifically xanthates and dithiophosphate collectors that allowed differential flotation of sulfide minerals Weinig and Carpenter 1937 Rabone 1939 Richards and Locke 1940 Taggart
·This is an overview of setting up and conducting a flotation rate test The test is a means of determining the flotation characteristics of an ore It is conducted in a laboratory scale cell usually with a volume of two point five litres

·Flotation constitutes a separation process that originated from mineral processing Nowadays wider applications have been found and compared to flotation for water and wastewater treatment Stress in the present review paper was mainly applied to heavy metal ions recovery by flotation and the respective mechanism followed being either ion precipitate
·Flotation had its beginning in mineral ore processing and as such has been used for a long time in solid/solid separation applications using stable froths to selectively separate different minerals from each other Kitchener 1985 Regarding applications of flotation in wastewater and domestic sewage treatment civil and chemical engineers have used
·Due to the limitation of freshwater sources and increasingly stringent disposal standards [13 74 79] the minerals industry has attempted to increase water use efficiency reduce freshwater utilization and minimize water discharge or seek alternatives to fresh water [57 59 78 84 101] It is widely accepted that flotation is the most popular mineral processing
·Flotation is a process in Liquid Solid Separation technology whereby solids in suspension are recovered by their attachment to gas usually air bubbles usually with objective of removing the solids from the liquid The particles most effectively removed are in the size range from 10 to 200 μm The particle bubble aggregates that are formed have a density less than
The use of power ultrasound in mining L Gaete Garretón in Power Ultrasonics 2015 The flotation process One of the most used processes to concentrate mineral from a mine is flotation To perform a flotation process the mineral is finely ground particle sizes between 50 and 150 μm then the ground mineral is mixed with water in a container called a flotation cell
