Abstract
The review of laser application in mining is followed by discussion of experimental treatment of carbonate rocks by the continuous fiber-optic yutterbium laser radiation at output capability of 600 W. Local disintegration of carbonate rocks is estimated with a view to show the possibility and practicability of laser-aided means and technologies in mineral mining and processing.
