3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 Agents used to effect or facilitate the flotation process. 3.2 In the flotation process, it is used to control the size of the bubbles and maintain the stability of the foam. 3.3 The agent added to the slurry to improve the adhesion between solid particles and air bubbles. 3.4 It has the properties of both collector and foaming agent, and can selectively act on the mineral surface to make it hydrophobic in the process of coal slime flotation. It can also orientate adsorption and arrangement on the gas-liquid interface, reduce the gas-liquid surface tension, and promote the formation of a large number of moderately sized gas in the slurry. A certain stability of the bubbles, to prevent the merger of the bubbles, to ensure that the mineralized bubbles float up to form a flotation agent that scrapes out the foam layer.
