21	Sorting of ores with detectable compounds	US100618	1979-12-05	US4347125A	1982-08-31	Peter M. Di Giacomo
A process for separating ore particles from gangue particles comprises the steps of (1) conditioning the particles with an agent comprising a compound having both a surface-selective functional group and a detectable moiety, to selectively coat either the ore particles or the gangue particles, to the substantial exclusion of the other; (2) detecting the coated particles; and (3) separating the detected, coated particles from the substantially uncoated particles. In one embodiment, the detectable moiety is fluorescent and detecting is performed under ultraviolet radiation.
22	Thermal convection counter streaming sedimentation method for controlling the sex of mammalian offspring	US641501	1975-12-17	US4067965A	1978-01-10	Bhairab C. Bhattacharya
A method and apparatus for controlling the sex of mammalian offspring through separation of X-chromosome female producing sperm and Y-chromosome male producing sperm. The separation is accomplished by producing a thermal convection counter stream within a sedimentation column containing a universal medium with sperm suspended therein, and subsequently allowing the two sperm populations to sediment into different fractions according to different densities. The positive and negative geotaxis thus applied to the sperm facilitate a more efficient separation than has been previously obtained. The apparatus used to accomplish this separation includes means for producing a temperature differential between axial and peripheral portions of the medium contained in the sedimentation column thus creating the necessary thermal convection counter stream, and may also comprise a laser capable of scanning the length of the column and laser detecting means to determine the distribution of sperm produced within the medium.

27	Material separation efficiency determination employing fluorescing control particles	US416710	1989-10-03	US5024753A	1991-06-18	Colin D. Chriswell; Richard Markuszewski; William H. Buttermore
An improved material separation system and method utilizing control particles of generally known physical characteristics as tracer particles through the separation process. The control particles are generally the same or similar to the materials being separated and are coated with or bonded to a fluorescing dye. The control particles are mixed with the material to be separated prior to separation. The mixture is imposed with a energy source which excites the fluorescent dye causing fluorescing emission. The fluorescing emission is detected at the output of the separation of the mixture to determine if the separation is operating efficiently and as desired.
28	Combination feedforward-feedback froth flotation cell control system	US562056	1990-08-02	US5011595A	1991-04-30	Gary F. Meenan; Hayward Oblad
A control system having optoelectric detectors responsive to different solids concentrations and character of the solids of a slurry, the signal of the detectors being input to a process controller which adjusts the rate of addition of chemicals to the feed stream of a froth cell to control the separation of solids from impurities. The impurities pass out of the cell as tailings. The controller calculates a feedforward output from the signals from detectors sensing different slurry conditions in the process feed stream, and the controller output adjusts the addition of different chemicals (additives) to the processing cell. The controller also calculates a feedback output after receiving a signal from a third detector in the tailings which monitors the extent of separation and recovery of solids from the processing cell.

31	Thermal convection counter streaming sedimentation and forced convection galvanization method for controlling the sex of mammalian offspring	US373143	1982-04-29	USRE32350E	1987-02-10	Bhairab C. Bhattacharya
A method and apparatus for controlling the sex of mammalian offspring by separation of the X-chromosome female producing sperm and Y-chromosome male producing sperm according to their different characteristics of density of the respective cells and electric potential on the respective cell surfaces. Separation is accomplished by first producing at thermal convection counter stream within a sedimentation column containing a universal medium with sperm suspended therein and allowing the two sperm populations to settle into different fractions according to different densities. Subsequently, the fractions are further separated and concentrated utilizing convection galvanization. The positive and negative geotaxis applied to the sperm during thermal convection sedimentation in combination with galvanic forces applied during the convection galvanization facilitate a more efficient separation than previously obtained. This is due to the fact that a greater degree of separation of X and Y sperm is achieved by subjecting an unbalanced population of sperm cells, i.e., one predominating in X or Y cells, to convection galvanization. Thermal convection counter streaming sedimentation has been found to be a preferred method for attaining this unbalanced sperm population. The apparatus used to accomplish the above separation includes means for producing a temperature differential between axial and peripheral portions of the medium contained in the sedimentation column, thus creating the necessary thermal convection counter stream, as well as an electrophoreses cell comprising a convection column disposed between the two electrodes of the cell. Alternatively, the sedimentation apparatus and the convection galvanization apparatus may be combined. Additionally, the apparatus may comprise a laser capable of scanning the length of the thermal convection sedimentation column as well as laser detecting means to determine the distribution of sperm produced within the medium therein.

A process for separating limestone ore particles from gangue particles comprises the steps of (1) conditioning the mixed particles with an agent comprising a compound having both a surface-selective functional group and a fluorescent moiety, to selectively coat either the ore particles or the gangue particles, to the substantial exclusion of the other; (2) irradiating the mixture to cause fluorescence in the coated particles; and (3) separating the fluorescing, coated particles from the substantially uncoated particles. The process may be used to separate by coating either the ore particles or the gangue particles.
33	Automatic control apparatus for a grain separator	US190762	1980-02-29	US4318806A	1982-03-09	Toshihiko Satake
An automatic control apparatus of a grain separator for precisely separating a mixture of soil particles and grain having different hue and specific gravity, wherein the grain separator includes a soil discharge opening disposed at the front end of a separating plate which is inclined with a forward elevation in order to perform oscillations back and forth at a larger angle than said inclined angle, and a grain discharge opening disposed at the rear end thereof.The automatic control apparatus is equipped with a light source and a light receiving element at the front end of said separating plate to detect the intensity of the ray reflected from the mixture of soil and grain, at which said light receiving element produces a signal which actuates an electromagnetic driving means to allow or block the discharge of materials from the soil discharge opening, thus discharging only soil particles from the discharge opening.
34	Product separator	US344697	1973-03-26	US3933249A	1976-01-20	Robert A. Welsh; Albert W. Deurbrouck
A secondary light sensitive photoelectric product separator for use with a primary product separator that concentrates a material so that it is visually distinguishable from adjacent materials. The concentrate separation is accomplished first by feeding the material onto a vibratory inclined surface with a liquid flow, such as a wet concentrating table. Vibrations generally perpendicular to the stream direction of flow cause the concentrate to separate from its mixture according to its color. When the concentrate and its surrounding stream reach the recovery end of the table, a detecting device notes the line of color demarcation and triggers a signal if it differs from a normal condition. If no difference is noted nothing moves on the second separator. However, if a difference is detected in the constant monitoring of the color line's location, a product splitter and recovery unit normally positioned near the color line at the recovery end, moves to a new position. In this manner the selected separated concentrate is recovered at a maximum rate regardless of variations in the flow stream or other conditions present.
35	Automatic grader for sorting objects according to brightness and color tones	US36057073	1973-05-15	US3854586A	1974-12-17	PERKINS J
A system and apparatus for grading and sorting tobacco leaves and other objects according to brightness and two color tones are provided. The tobacco leaves or objects are caused to traverse a background plate of known color and both are impinged by polychromatic light. The light reflected therefrom in three distinct spectral bands is detected and analyzed according to a predetermined mathematical relationship to compare the brightness and two color tones of the said leaves or objects to standards which are selectively dialed in to the apparatus. Logic circuitry is provided to constrain acceptance or rejection of the leaves or objects by the system in response to a determination that at least one of the characteristics of brightness and two color tones exceeds a predetermined deviation from the preset standards. One of the spectral bands is chosen to provide uniform reflectivity from the series of leaves or objects being sorted to normalize the size of the various objects to that of the background surface.
36	Beneficiation of new york state talc	US31900172	1972-12-27	US3837582A	1974-09-24	BAAK T
Process of beneficiating Gouverneur, New York talc ore to produce a high purity, platy talc substantially free of tremolite. The process involves crushing the ore and irradiating the crushed ore with short wavelength ultraviolet radiation to cause the talc in the crushed ore to fluoresce predominantly white and the tremolite in the crushed ore to fluoresce a predominantly non-white color. The irradiated crushed ore is then separated into a first portion in which the fluorescent areas of the constituent rocks fluoresce predominantly white, and a second portion in which the fluorescent areas of the constituent rocks fluoresce a predominantly non-white color. The rocks in the first portion are crushed further preferably to a particle size of minus 100 Tyler mesh, and are subjected to at least one froth flotation step. The talc recovered from the froth formed during the last froth flotation step is characterized by a G.E. brightness about 90 and a tremolite content of less than 1.0 percent by weight.

A method and apparatus for sorting articles, such as lumps of limestone and dolomite that differ in color. Each article is illuminated and the light reflected therefrom is directed to a pair of photocells, each having a filter for passing a respective frequency of light. A quotient is derived from the signals generated in the photocells and the quotient is employed for actuating an ejector when the derived quotient is different from that desired.
38	Ore separation	US3722676D	1971-08-23	US3722676A	1973-03-27	MATHEWS T
There is disclosed herein an apparatus for detecting and separating a desired ore or mineral from a quantity of ore. The apparatus includes a plurality of selectively deflectable flowing fluid streams. The streams are controlled to displace the desired mineral particles from the quantity of ore. Pivotally mounted arcuate tubes normally divert the fluid streams when then are not acting to displace particles, but these tubes are selectively movable to allow the streams to hit desired particles. A screen is used for conveying the ore past the fluid streams in such a manner that the streams may act through the screen to displace the selected particles.
