Laser mining would allow for a no explosive option and not need huge machines increasing output as well. Also lasers could make more precise cuts rather than blades which would never get dull.
The application of the “Graduated Optical Colimator” (GOC) for the mining industry consists of a one-kilowatt optical power fiber laser to selectively spall igneous geological formations containing narrow veins of precious metals.
Merger said the prototype addresses key issues like mining using less explosives, chemicals and waste.
