Abstract:
1. Method for breaking up ore, characterized in that the ore is loaded respectively at least once with coherent near infrared radiation ( 4 a ), non-coherent near infrared radiation ( 4 b ), at least one electrical alternating field ( 4 c ) with a frequency greater than 300 GHz, at least one magnetic alternating field ( 4 d ) with a frequency greater than 300 GHz, at least one electromagnetic alternating field ( 4 e ) with a frequency greater than 300 GHz, or a combination thereof, with a device, arranged at a spacing to the ore, that generates coherent near infrared radiation ( 4 a ), non-coherent near infrared radiation ( 4 b ), at least one electrical alternating field ( 4 c ) with a frequency greater than 300 GHz, at least one magnetic alternating field ( 4 d ) with a frequency greater than 300 GHz, at least one electromagnetic alternating field ( 4 e ) with a frequency greater than 300 GHz, or a combination thereof, wherein ore mineral ( 2 ), ore minerals ( 2 ), absorbing components ( 2 ), or ore mineral ( 2 ) and absorbing components of the ore absorbs or absorb energy from the coherent near infrared radiation ( 4 a ), the non-coherent near infrared radiation ( 4 b ), the at least one electrical alternating field ( 4 c ) with a frequency greater than 300 GHz, the at least one magnetic alternating field ( 4 d ) with a frequency greater than 300 GHz, the at least one electromagnetic alternating field ( 4 e ) with a frequency greater than 300 GHz, or a combination thereof and lode matter ( 3 ) does not absorb, or absorb only minimally, the energy so that, by means of resulting stresses, cracks 5 are generated in the ore or the ore splits apart, wherein the ore is sequentially or simultaneously subjected to loads selected from the group consisting of coherent near infrared radiation, non-coherent near infrared radiation, the electrical alternating field with a frequency greater than 300 GHz, the magnetic alternating field with a frequency greater than 300 GHz and the electromagnetic alternating field with a frequency greater than 300 GHz.
