The grade of tungsten raw ore in a metamorphic sandstone quartz veinlets zone is low,with WO3 grade of around 0.15%,and wolframite accounts for 96.09%of the total tungsten content.There are various types of metal sulfides in ores,but their content is low,which belongs to easily selected wolframite ore.In order to recover tungsten resources from this ore,firstly,a systematic study of process mineralogy was conducted to identify the mineralogical factors affecting tungsten beneficiation index.Then,based on this,the experimental study of ore washability was carried out by using the process of gravity concentration first and then flotation,and the effect of the scheme was analyzed in detail.The results showed that the yield of tungsten concentrate was 0.204%,the grade of WO3 was 48.88%,the recovery of WO3 was 72.315%;the copper concentrate rate is 0.098%,the copper grade is 23.35%,and the copper recovery rate is 51.99%.Finally,it is recommended to use the process of"shaking table roughing+copper recovery from the flotation of rough concentrate"to recover tungsten resources from the ore.Reasonable suggestions are provided.
