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.

Abstract: The invention relates to a pole terminal for producing an electrical connection. Said pole terminal comprises a metallic conductive body which is surrounded by an insulating body which can be fixed to the housing of an electrical appliance, and on which a tensioning nut can be screwed, said tensioning nut clamping the electrical conductor to be connected against the conductive body, establishing an electrical contact. The aim of the invention is to improve one such pole terminal in such a way that the conductive body can be produced from a material which is highly conductive, such as silver or copper. To this end, the conductive body is produced from a material exhibiting higher conductivity, by means of noncutting deformation, and is connected to the surrounding insulating body to form a composite body. Preferably, the conductive body is embodied as a stamped part which is machined by bending strain.
