摘要：
The influencing mechanisms of grinding environment, grinding medium, mechanical force, mill types and grinding aids on surface properties and flotation behavior of sulfide and oxidized minerals were systematically reviewed. It was concluded that, for sulfide ores, grinding can mainly affect the crystal structure and pulp electrochemical properties of mineral particles. While for oxidized and silicate minerals, grinding dominantly influences the exposure degree of crystal surfaces, reactivity, shape index and roughness of mineral particles, and ultimately exerts influence on mineral flotation behavior. In the near future, the main researches should be concentrated on coordinated optimization of various factors in grinding process to produce mineral particles with specific crystal structure, shape index and crystal surface exposure which will lead to a precise control of mineral flotation behaviour and hence separation efficiency. © 2019, Science Press.
