| 183 | Apparatus and method for sorting and recombining minerals into a desired mixture | US10874087 | 2004-06-22 | US07380669B2 | 2008-06-03 | Earl L. Hacking, Jr.; Thomas A. Swaninger |
| A method and apparatus is employed to create a mixture having a desired composition. A raw material is separated in a pair of density separators into constituent parts. Those parts are then recombined in a desired fashion using a pair of splitters to create an intermediate mixture and delivered to a third density separator. The third density separator processes the intermediate mixture to create a final mixture having the desired composition. | ||||||
| 184 | Dycon gravity mineral recovery apparatus and process | US11492644 | 2006-07-25 | US20080023377A1 | 2008-01-31 | George P. Baummer |
| A gravity mineral recovery apparatus and process uses stratification to separate the relatively heavier valuable particulates from the lighter tailings in ore. A housing holds a process chamber therein, the chamber capable of oscillating within the housing. Ore is gravity fed into the process chamber and falls toward the bottom with the ore channeled to the outer sidewall of the process chamber by a deflector that creates an annular passage within the chamber. The oscillation of the chamber causes the heavier particulate to stratify into circumferentially disposed hoppers while the tailings are discharged through a central chute to a tailings hopper. The hoppers have compound sloped sidewalls and have a sensor for opening a discharge valve within the hopper once a given concentration is achieved. A series of sensors within the tailings hopper control a tailings discharge valve as well as an ore feed valve. Water constantly flows through the system yet does not participate in the actual transport of the particulates. | ||||||

| 188 | Dual-cell mechanical flotation system | US10297635 | 2001-06-07 | US06955763B2 | 2005-10-18 | Melvin O. Stacy; Kenneth Tolmie; James C. T. Chen |
| It has been discovered that a mechanical flotation system having only two cells can be nearly as efficient as one having more cells, yet provide an apparatus with a considerably smaller footprint, significantly reduced capital and operating costs, as well as be resistant to floating oil recovery platform wave effects. The dual-cell mechanical flotation system has, in sequential order, an inlet chamber and two gasification chambers or cells, each with at least one gas ingestion and mixing mechanism, and a discharge chamber. A common primary skim collection channel atop the partition dividing the gasification chambers efficiently channels away the bulk of the floating collected matter. At least one baffle depending from the top of the vessel near the primary skim collection channel helps dampen the action of the fluid containing the suspended matter when the vessel is affected by wave motion against the floating oil production platform. | ||||||

| 191 | Method for reblending sand | US09817679 | 2001-03-26 | US06796432B2 | 2004-09-28 | Trenton L. Soldwish-Zoole; Franklin E. Squires |
| A method of reblending sand in a classification tank having multiples stations and discharge valves within each station includes the steps of delivering sand to the tank; calibrating the tank to analyze the raw feed material and develop discharge rates, flow multipliers, and a mathematical model of the tank; and inputting a specification or quantity and sieve size distribution for a reblended sand product into a computer for controlling the tank. Then the tank is operated in a production mode and the discharge valves at each station of the tank are adjusted by the computer for percent open time and discharge rate. With one algorithm, the computer identifies which station has the most of a sieve size that is out of specification and diverts material at that station by closing the appropriate discharge valve(s). In another algorithm especially adapted to minimize fines, the computer begins with the station most remote from the inlet and diverts material by repeatedly reducing the valve open percentage of the appropriate valve at that station by a given amount until the specification is met or the valve is always closed. Once the valve is always closed, the computer moves a station closer to the inlet and repeats the process. Once a primary product is being produced to specification, the same algorithm can be used to control the production of a secondary product. | ||||||
| 192 | Process for the physical segregation of minerals | US09669076 | 2000-09-25 | US06675064B1 | 2004-01-06 | Jon C. Yingling; Rajive Ganguli |
| With highly heterogeneous groups or streams of minerals, physical segregation using online quality measurements is an economically important first stage of the mineral beneficiation process. Segregation enables high quality fractions of the stream to bypass processing, such as cleaning operations, thereby reducing the associated costs and avoiding the yield losses inherent in any downstream separation process. The present invention includes various methods for reliably segregating a mineral stream into at least one fraction meeting desired quality specifications while at the same time maximizing yield of that fraction. | ||||||

| 196 | Method and means for sand reblending | US09266037 | 1999-03-11 | US06311847B1 | 2001-11-06 | Trenton L. Soldwish-Zoole; Franklin E. Squires |
| A method of reblending aggregate includes delivering aggregate of various sizes to the classification tank having a plurality of stations with primary and secondary discharge valves. The tank is then calibrated to determine raw feed analysis, discharge rates and the flow multipliers needed to develop a mathematical model of the tank. Inputting the calibration information data and the desired production specification into a computer allows the tank to be operated and controlled with appropriate adjustments in discharge rates and valve percent settings at each station. This method provides more accurate control than the existing min-max control methods. The apparatus for this method includes the tank, a pumping device, and a computer interconnected with a PLC and electrohydraulic mechanisms for valves at each tank station such that both the discharge rate from each station and the valve percent settings of the individual valves at each station are variable and controllable. | ||||||
