AB  - This dataset focuses on the selective grinding and dissociation process of complex fine-grained toxic sand gold mines, covering the impact of grinding process parameters and grading equipment parameters on grinding fineness, grading efficiency, and mineral dissociation degree. This includes the effects of different grinding media, pH values, time, concentration, steel ball filling rate, sand return ratio on grinding efficiency, the influence of cyclone feed fineness, pressure, and sand settling nozzle diameter on grading products, as well as data on the changes in grading efficiency and the dissociation degree of arsenopyrite and pyrite monomers before and after the application of selective grinding dissociation grading technology. This dataset provides basic data support for optimizing the grinding and grading process, improving the dissociation efficiency of gold bearing minerals, and improving flotation indicators.  This data mainly covers the effects of grinding medium, pH value, grinding time, grinding concentration, steel ball filling rate, sand return ratio on grinding fineness and flotation indicators, the influence of grading feed fineness on cyclone overflow and bottom flow fineness, the influence of cyclone feed pressure on grading efficiency, the influence of sand settling nozzle diameter on grading products, and the experimental data related to the effects of selective grinding dissociation grading technology on grading efficiency, arsenopyrite and pyrite monomer dissociation before and after application.  1. Name explanation: Grinding medium: refers to the type of medium used in the grinding process; Grinding fineness: the proportion of a certain particle size in the grinding product; Steel ball filling rate: the percentage of the volume of steel balls inside the mill to the effective volume of the mill; Return sand ratio: the ratio of the amount of sand returned in the grinding cycle to the amount of raw ore; Classification efficiency: the efficiency
