ANALYSIS OF THE GRANULOMETRIC COMPOSITION OF THE ORE MASS DURING UNDERGROUND MINING OF DISSEMINATED COPPER-NICKEL ORES
With the depletion of industrial ore reserves, the acuteness of the problem of improving the quality of ore raw materials increases, since there is objectively a correlation between the granulometric composition (size) of useful components in ores and their stable content. At the Norilsk copper-nick...

With the depletion of industrial ore reserves, the acuteness of the problem of improving the quality of ore raw materials increases, since there is objectively a correlation between the granulometric composition (size) of useful components in ores and their stable content. At the Norilsk copper-nickel deposits, there is a tendency for an intensive decrease in the content of metals in industrial reserves, which is accompanied by an increase in the indicators of variability in the quality of ores. It was found that the value of the nickel content in pieces of broken- off ore mass with a particle size of 5 to 35 cm changes in the aisles from 0.34 to 0.2%, and copper, respectively, from 1.3 to 0.22%, that is, the range of fluctuations is, respectively, 0.14 and 1.08% or relative change - 1.7 and 5.9 times. Mixing and uniform distribution of the average content of useful components in the chipped ore depends on its flowability and lumpiness, determined not only by the average size of the lumps, but also by the granulometric composition of the ore mass. In this work, the analysis of the granulometric composition of the broken-off minerals in the face and the establishment of the weighted average size of a piece of ore mass during underground mining of disseminated copper-nickel ores were considered on the example of the "Norilsk-1" deposit, in the conditions of the "Zapolyarny" mine. |
