Upgrading of Vang Danh Coal Fines Using Reflux Flotation

Oct 26, 2020· This paper presents the test results of coal fines samples −0.3 mm from Vang Danh underground coal mine (in Quang Ninh, Vietnam) by flotation in a laboratory Reflux flotation cell. The test results show that combined clean coal can be received with the ash content less than 15% and the combustible recovery of more than 80%.

Flotation Cell an overview | ScienceDirect Topics

Improved metallurgical performance of column cells in iron ore flotation is reported and attributed to froth washing, which reduces the loss of fine iron minerals entrained into the froth phase (Dobby, 2002). The Brazilian iron ore industry has embraced the use of column flotation cells for reducing the silica content of iron concentrates.
