摘要： The interrelated group of inventions relates to methods and devices for raw material lump separation and can be used for dressing ferrous and non-ferrous metal ores, mining chemical feedstock, secondary raw material and technogenic waste. The essence of the inventive method and device lies in that a useful component containing lump and a barren rock is irradiated by an ultrahigh frequency electromagnetic field (UHF). Said radiation frequency is selected in such a way that the electromagnetic wave penetration depth dependent of lump material properties is greater than the lump maximum linear dimension at the peak attenuation of the electromagnetic wave. UHF electromagnetic radiation energy absorbed by the lump material initiates the heating of the components thereof, wherein the component exhibiting a greater electrical conductivity absorbs the greater amount of UHF energy than the component exhibiting a lower electric conductivity during the same time, whereby the heating temperatures of the useful component and the barren stock measured after irradiation are different. The temperature law depends on the mass ratio of the lump components exhibiting different properties and is recorded by a thermographic system. Said invention makes it possible, under the same conditions, to increase the useful component content from 6-10 % to 18-25 %, the increment of the useful component mass ratio by 4.5 %, to reduce the useful component tailing up to 3 % and the energy consumption by 5 % by decreasing the raw material dilution during the processing thereof.

摘要： The present interdependent group of inventions pertains to methods of and devices for lump separation of raw material and may be used in ferrous and non-ferrous metal ore dressing, concentration of mining and chemical raw materials, processing secondary raw materials and technological wastes.
The method and the device are based on the idea that a lump comprises a useful component and refuse, and such lump is exposed to ultrahigh frequency (UHF) electromagnetic field. The frequency selected is such that electromagnetic wave penetration depth will exceed the maximum linear size of a lump under conditions of maximum damping of electromagnetic wave, which depends upon characteristics of such lump material. The energy of UHF electromagnetic radiation absorbed by a lump material causes heating of the lump components. A component with higher electric conductivity will absorb UHF energy higher than UHF energy absorbed by a component with lower electric conductivity during the same period of time. As a result, after removing the UHF field the useful component and the refuse will be heated to different temperatures. A lump temperature profile will depend on mass ratio of components with different properties within such lump, and said temperature profile is registered by a thermographic system.
The invention implementation will make possible to increase the useful component content from 6 ~ 10% to 18 ~ 25% under conditions and loads unchanged, increase weight % of the useful component to 4.5% while decreasing its content in tails to 3%, decrease the total electric energy consumption by 5% due to decrease of refuse content in the raw material being concentrated. 7 independent claims, 6 figures
