  • Effect of Frother on Flotation at Different Particle Size

    Plant evaluation 4 was conducted on the Clarion 4A coal seam. This plant utilizes a split flotation process. Froth flotation slurry is split into two particle size fractions, a 0.5 mm by 0.15 mm coarse particle fraction and a 0.15 mm by 0 mm fine particle fraction. The coarse particle slurry contains 17% solids by weight at a pH of 6.5.

  • Switching and optimizing control for coal flotation

    Oct 17, 2017· Introduction. In the process of coal preparation, flotation is used to separate the ash-forming mineral matter and the carbonaceous materials of fine coal below 0.5 mm in size [1,2].This process is widely applied in countries such as China, USA, Australia, Canada and India [].Flotation columns are extensively studied and used as an efficient coal flotation equipment due to many
