Optimization study of jigging ore-dressing process for an ore-dressing plant in Hainan
Taking the jigging system of an ore-dressing plant in Hainan as the research object,this study addresses the issue of decreased jigging product indicators caused by variations in ore grade.Through physical phase analysis,sampling surveys,and other methods,research was conducted on the granularity and grade of the selected ore,the coef-ficient of the electronic belt scale range,and the grade of products at each particle size,proposing targeted optimization measures for jigging ore-dressing process.The process flow was optimized by controlling the input ore granularity,adjusting jigging parameters,and selecting ore samples ranging from 0 to 75 mm.Significant errors were observed between the measured weights of samples and the readings of the electronic belt scale,with a weight error of up to 16%for samples.After optimizing the coefficient of the electronic belt scale range,the production requirements were met.Comparison between test samples and production samples showed that the actual grade of jigging crude ore,mid-dlings,and powdered ores was lower than that of production samples,while the actual grade of jigging tailings was higher,indicating inadequate representativeness of production sampling,which should be adjusted to sectional sampling.The research results have important reference value for optimizing jigging ore-dressing processes.
