Abstract
To address the issues of data accuracy and reliability in the survey of a SAB(Semi-autogenous grinding+ball milling)comminution circuit in large copper-molybdenum mines,and to enhance the feasibility of circuit performance evaluation and the optimi-zation of process and equipment parameters,this study investigates and explores the sampling methods for the SAB comminution circuit survey in a super-large copper-molybdenum mine.The results show that by adjusting the sampling sequence and placing the collection of the SAG(Semi-autogenous grinding)mill feed sample later,the influence of short-term ore feed interruptions on product slurry density and particle size fluctuations is effectively avoided.For high-flow cyclone classification sampling,a combination of automatic sampling and manual check sampling was adopted.Specially designed sampling devices,such as a SAG mill discharge sampling scoop,a cyclone sampling T-shaped baffle,and a pebble sampling bucket,effectively solved the challenges of high-flow sampling in the SAB comminu-tion circuit and improved the accuracy and reliability of sampling.The sampling method studied in this paper provides reference and guidance for SAB comminution circuit surveys in similar domestic concentrators.关键词
