By controlling the potential conditions of the flotation system and the hydrometallurgical system, regulating the flotation separation behavior of minerals, and catalyzing the dissolution process of minerals, it is hopeful to develop a sulphide ore potential control flotation technology and slurry electrolysis technology with the slurry potential as a control parameter. And mineral bio-extraction technology, these reactions will cause the reductive nature of the grinding process.
Therefore, the slurry potential of the grinding process is much lower than the potential in the flotation machine. In addition to the reducibility of the iron balls in the grinding, flotation is an inflating process. Oxygen is fed into the flotation machine to make the slurry Potential increase. If collectors, hammer breakers, and lime are added to the mill for grinding and stripping with the sulphide ore, the potential of the slurry in the action of the sulphide ore and the collector will facilitate the separation of the sulfide minerals.
The following illustrates the problem with galena, pyrite, and sphalerite as an example. In the grinding process, electrochemical interactions and electrocatalysis occur between galena, pyrite, sphalerite and grinding balls. Among all the sulphide minerals, pyrite has a high surface electrostatic potential, and the higher the solid, the lower its electrochemical activity. According to the size of the electrochemical activity: Pyrite sphalerite galena iron.
