    • 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.

    • A method for separating resins of an exhausted, mixed bed resin. The exhausted, mixed bed resin includes (a) an exhausted cation exchange resin having a first density and a first conductance value when suspended in the classifying fluid at a first concentration; (b) inert particulate material having a second density that is less than the first density and having a second conductance value when suspended in the classifying fluid that is at most about 30 percent at the conductance of the cation exchange resin when measured in the classifying fluid at the first concentration; and an exhausted anion exchange resin having a third density that is less than the second density and also having a third conductance value that is greater than the second conductance value when the exhausted anion exchange resin is suspended in classifying fluid and measured at the first concentration. The mixed resin bed is classified with the classifying fluid in a container to form a vertical column of resin such that the cation exchange resin forms a bottom layer, the inert resin forms an intermediate layer and the anion exchange resin forms a top layer. The slurry is passed out of the bottom of the container while the classification is maintained. The conductance value of the passing slurry is measured, and after the conductance value has become substantially constant, the conductance value is stored to determine an initial conductance value. Subsequent conductance values of the passing slurry are also measured and those subsequent conductance values are compared to the initial conductance value. The passage of the slurry out of the container is terminated when the first subsequently measured conductance value is at most about 30 percent of the initial conductance value. A second embodiment of the invention utilizes only cation and anion exchange resin. The method steps are substantially the same as recited with the embodiment utilizing the inert resin, except that the slurry passage is terminated when the first subsequently measured conductance value is at most about 55 percent of the initial cation exchange resin conductance.
    • 一种用于分离排出的混合床树脂的树脂的方法。 耗尽的混合床树脂包括(a)当以第一浓度悬浮在分级流体中时具有第一密度和第一电导值的排出的阳离子交换树脂; (b)惰性颗粒材料,其具有小于第一密度的第二密度,并且当悬浮在分级流体中时具有第二导电值,当在分级流体中测量时,其在阳离子交换树脂的电导下为至多约30% 在第一集中; 以及当排出的阴离子交换树脂悬浮在分级流体中并以第一浓度测量时,具有小于第二密度的第三密度的耗尽的阴离子交换树脂,并且还具有大于第二导电值的第三电导值。 将混合树脂床与容器中的分级流体分类以形成垂直的树脂柱,使得阳离子交换树脂形成底层,惰性树脂形成中间层,阴离子交换树脂形成顶层。 在保持分类的同时,将浆料从容器的底部排出。 测量通过的浆料的电导值,并且在电导值变得基本恒定之后,存储电导值以确定初始电导值。 还测量通过浆料的后续电导值,并将那些随后的电导值与初始电导值进行比较。 当第一个随后测量的电导值至多为初始电导值的约30%时,将浆料从容器中流出以终止。 本发明的第二个实施方案仅使用阳离子和阴离子交换树脂。 方法步骤基本上与使用惰性树脂的实施例所述相同,只是当第一后续测量的电导值为初始阳离子交换树脂电导率的至多约55%时,浆料通道终止。

    • A process for separating coal particles from ROM coal containing coal particles and refuse particles, by treating particulate ROM coal with a detectable marking agent in a manner to attach the marking agent preferentially to only one class of particles in the R0M coal, and by thereafter separating particles carrying the marking agent from the treated particulate ROM coal. In a preferred embodiment, a method is disclosed for the separation of coal from run of mine (ROM) coal containing particles of coal and refuse, which comprises conditioning the ROM coal with a coating agent capable of selectively coating the particulate coal to the substantial exclusion of coating the refuse, which coating agent is at least one alcohol containing from about 6 to about 22 carbon atoms. Combined with said coating agent is a fluorescent dye in a quantity to make the coated particles of coal fluoresce upon excitation to a degree sufficient to distinguish the coated coal particles from the substantially non-coated refuse. Exciting (as with ultraviolet light) the fluorescent dye coupled to the coal particles induces fluorescence and enables separating the fluorescing, coated coal particles from substantially non-fluorescing, non-coating refuse particles.
