Upgrading of Vang Danh Coal Fines Using Reflux Flotation Cell

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%.

Jameson cell Wikipedia

The high intensity of the Jameson Cell means that it is much shorter than conventional column flotation cells (see Figure 1), and it does not require air compressors to aerate the suspension of ground ore particles and water (known as a slurry or pulp) in the flotation cell. The lack of a requirement for compressed air and the lack of moving parts means that power consumption is less than for
