22 | Method for thermographic lump separation of raw material (variants) and device for carrying out said method (variants) | US10561891 | 2004-06-03 | US07541557B2 | 2009-06-02 | Volodymur M Voloshyn; Viktor Y Zubkevych |
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. | ||||||

Apparatus and method for sorting scrap metal pieces dependent on the type of metal therein. The apparatus includes a conveyor and a feeding arrangement to feed the scrap metal pieces on to the conveyor, together with an X-ray fluorescence detector to examine each metal piece and determine the type of metal as a result of the characteristic X-rays emitted. A respective control signal is utilized to move pegs on the conveyor so as to permit the respective metal piece to exit from the conveyor along a respective path and to enter a bin for that particular type of metal. In this way scrap metal pieces of different metal are collected in different bins for subsequent processing. | ||||||
24 | Separation of limestone from limestone ore | US897740 | 1978-04-19 | US4208272A | 1980-06-17 | Brij M. Moudgil |
A method for the separation of limestone from a particulate limestone ore containing particles of limestone and gangue which comprises conditioning the limestone ore with at least one coupling agent selected from saturated and unsaturated carboxylic acids containing from about 4 to about 22 carbon atoms, or at least one coupling agent selected from the group consisting of aliphatic amines containing from about 8 to about 22 carbon atoms, and beta amines containing from about 7 to about 21 carbon atoms, to selectively coat the limestone or the gangue in the ore to the substantial exclusion of the other in combination with providing at least one fluorescent dye to said coupling agent; radiating the conditioned ore to excite and induce fluorescence of the fluorescent dye to a degree sufficient to distinguish the coated particles from the non-coated particles and separating the fluorescing, coated particles from the nonfluorescing, non-coated particles. | ||||||
25 | Automated continuous classification and reblending system for sand and other granular material | US53380274 | 1974-12-18 | US3913788A | 1975-10-21 | MCCAULEY PORTER THOMPSON |
A continuous-operation automated control system for a water scalping tank or like apparatus in which granular material of different sizes accumulates at varying rates at a series of classification stations; the material is discharged to at least one specification reblending flume, in predetermined ratios, to produce a specification product, and excess material is discharged to an auxiliary flume. One classification station is designated a master station. Discharge at each station is initiated whenever sufficient material has accumulated to allow a relatively constant flow. Each station has a digital timer for measuring its flow to the specification product; the time of flow for the master station is continuously compared with the flow time for each secondary station in a pre-set ratio that may be different for each secondary station. When the comparison for any secondary station shows excessive cumulative flow from that station, its discharge is diverted from the specification flume to the auxiliary flume, but only until the master station flow catches up. When the comparison for any secondary station shows an inadequate cumulative flow, the master station discharge is diverted to the auxiliary flume until the secondary stations have all caught up.

28 | Conductionmetric resin separation | EP84105261 | 1984-05-09 | EP0128363A3 | 1986-11-20 | Salem, Eli |
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. |

37 | Device for manufacturing iron or non-ore-smelting type | US3752897D | 1971-06-17 | US3752897A | 1973-08-14 | ATSUKAWA M |
A device for manufacturing iron, in which by supplying an alternating current directly to the accumulation of a preheated iron-manufacturing raw material in the form of powder and particles a high-density current concentrated locally in the accumulation is formed. The reduction of iron oxide is carried out by applying Joule heat and electromagnetic force caused by the high density current to the raw material for manufacturing iron through which the current is flowing, thereby to soften a gangue material and simultaneously to aggregate iron particles, whereby in a non-ore-smelting state the iron in the form of a bare rod or particles is separated from the gangue material in the form of pumice.
