| Abstract: |
| Ore property of this copper dioxide has been studied through the methods such as chemical analysis, XRD, particle size distribution composition analysis and etc. and the effect of grinding fineness and reagent regulation on flotation has been investigated as well. The results indicate that the raw ore grade is 1.29%, copper oxidation rate is 92.25% and slime content is 65.59%. By closed circuit process of 1 stage of roughing, 3 stages of scavenging and 2 stages of cleaning flotation, 18.32% concentrate grade with 73.46% recovery can be obtained. It is difficult to beneficiate the copper ore because it is mainly cuprite with very high content of slime. |
