Abstract
The invention relates to methods and devices for breaking up ore. The methods and devices are characterized in particular in that ore mineral or ore minerals can be subsequently easily extracted. For this purpose coherent NIR radiation, non-coherent NIR radiation, at least one electric alternating field having a frequency greater than 300 GHz, at least one magnetic alternating field having a frequency greater than 300 GHz, at least one electromagnetic alternating field having a frequency greater than 300 GHz, or a combination thereof are respectively applied to the ore at least once by means of a device for generating the radiation, the at least one alternating field, or the radiation and the at least one alternating field, wherein ore mineral, ore minerals, absorbent components, or ore minerals and absorbent components of the ore absorb(s) energy from the radiation, the alternating field, or the radiation and the alternating field and said energy is not or is only slightly absorbed by the lode matter. Thus, advantageously, cracks are formed in the ore or the ore splits by means of the resulting stresses.
