Electrical blasting disintegration of copper-nickel ores conjointly with separation of particles by size

Absract The effect of electrical blast parameters is studied for grinding mineral materials by example of copper-nickel ore. It is shown that the average energy consumed by the electrical blasting is within 5-50 J/g. The particle disintegration mechanism has been considered at high and low electric conductivity of ore. It is established that grinding and separation of particles by size are possible to be performed conjointly in the same apparatus.
