METHOD AND DEVICE FOR OPENING ORE

摘要

FIELD: mining operations.;SUBSTANCE: invention relates to a method and device for opening ore. To create cracks or splits of ore, the device for opening ore is located at a distance from it. Ore is at least once exposed to radiation from the device of at least one alternating field or radiation and at least one alternating field. The device generates coherent radiation of near infrared spectral band, incoherent radiation of near infrared spectral band, at least one alternating electric field with frequency above 300 GHz, at least one variable magnetic field with frequency above 300 GHz, at least one variable electromagnetic field with frequency above 300 GHz, or a combination thereof. Ore mineral, ore minerals, absorbent components or ore mineral and absorbent components of ore absorbs or absorb the energy of the radiation, alternating field or the radiation and the alternating field. Gangue does not absorb this energy at all or absorbs only in small amounts.;EFFECT: ore mineral or ore minerals subsequently can easily be extracted.;12 cl, 4 dwg
