May 01, 2013 Fluorite flotation is usually realized with sodium lignosulfonate as depressant and fatty acid as collector at a high pH Crozier, 1992, Ayhan et al., 2006. In the case where feed ores contain a significant amount of fine particles, the sedimentation rate of fine particles was found to be significantly slow due to the effective dispersion of the fine particles when lignosulfonate was used resulting in a high-turbidity of recycled water in the flotation

Jul 01, 2003 The fluorite flotation tests were carried according to the flowsheet shown in Fig. 1. The fluorite ore sample was first wet-ground to be 90 minus 200 meshes. Then, the slurry was conditioned, while 1000 gton water glass and a given amount of collector were added. Also, enough sodium carbonate was added to adjust the slurry to a pH of 9.5, and ...Online Chat
Jul 01, 2020 The mineral samples of fluorite and calcite were ground to 2 m. 1.0 g of the mineral sample was added to 40 mL flotation cell, and the pH was adjusted to about 8.5 like in the flotation test. Then, the depressant and the collector were added and the slurry was reacted for 20 min.Online Chat
Fluorite CaF2, as an important strategic mineral source, is usually separated from calcite by the common froth flotation method, but this separation is still not selective enough. The development of a selective collector andor depressant is the key to achieving high selective separation. 1-Hydroxyethylidene-1,1-diphosphonic acid HEDP or H4L is widely used as an environmentally friendly ...Online Chat
The fluorite ore flotation process generally uses fatty acid collectors. In order to achieve a better flotation effect, a small amount of sulfide ore inhibitor can also be added to suppress the residual sulfide ore, so that the grade of fluorite concentrate can be improved. 2. Separation of fluorite and bariteOnline Chat
The best flotation is observed in Hallimond tubes while flotation is significantly reduced or absent in laboratory flotation machines. This is very likely a result of relatively long time of the TPC formation andor low hydrophobicity of fluorite, which is not enough to withstand the detachment force during enhanced hydrodynamics of larger ...Online Chat
Jul 01, 2011 When the gas holdup was 4.017 the recoveries of fluorite and scheelite were 91.30 and 80.36 respectively. However, when the cathode aperture was 150 m scheelite in the 3874 m sized fraction has a better floatation effect than the fluorite flotation recoveries of fluorite and scheelite were 81.32 and 67.35 respectively. 3Online Chat
