| 121 | Amine-aldehyde resins and uses thereof in separation processes | US11298936 | 2005-12-12 | US08702993B2 | 2014-04-22 | James Wright; Carl R. White; Kurt Gabrielson; John B. Hines; Lisa M. Arthur; Paul Hart; Richard Rediger |
| Amine-aldehyde resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These resins are especially useful as froth flotation depressants in the separation of bitumen from sand and/or clay or in the beneficiation of clay (e.g., kaolin clay) from an impure clay-containing ore. The resins are also useful for treating aqueous liquid suspensions to remove solid particulates, as well as for removing metallic ions in the purification of water. | ||||||

| Disclosed herein is a process for preparing transportation fuel and optionally a middle distillate, a diesel fuel, a heating oil, a jet fuel, a kerosene, an aviation gasoline, a gasoline fuel, or a lubricant base oil. The process includes the steps of (a) producing a naturally occurring aqueous fluid containing greater than 1 wt. % soluble carboxylic acids; (b) isolating at least a portion of the organic acids from the naturally occurring aqueous fluid; and (c) upgrading the isolated carboxylic acids. The step of upgrading the isolated carboxylic acids can include at least one of hydrotreating, hydrocracking, isomerization, esterification and FCC cracking. The aqueous fluid can then be used in processes for recovery of a mobile kerogen based product. Also disclosed herein is a process for preparing a biofuel comprising the organic acids isolated from naturally occurring aqueous fluid. | ||||||

| 129 | Method for removal of unburned carbon contained in fly ash | US12087069 | 2006-12-11 | US07703610B2 | 2010-04-27 | Kazuyoshi Matsuo; Kazuo Abe; Takao Suzuki; Shinichiro Saito |
| Disclosed is a method for removal of an unburned carbon contained in a fly ash material. The method comprises the steps of adding water to the fly ash to prepare a fly ash slurry; shearing the fly ash slurry using an agitating blade that can rotate at a high speed to generate an active energy on the surface of an unburned carbon by the shearing force, thereby imparting lipophilicity to the unburned carbon; and adding a collecting agent and a foaming agent to the slurry containing the lipophylized unburned carbon to cause the attachment of the collecting agent to the lipophylized unburned carbon, and at the same time, causing the attachment of the unburned carbon having the collecting agent attached thereto an air bubble to separate the unburned carbon by flotation. | ||||||
| 130 | Method and apparatus for treating animal waste and wastewater | US10679770 | 2003-10-06 | US07005068B2 | 2006-02-28 | Robert O. Hoffland |
| Novel methods and apparatuses are disclosed for the treatment of wastewater to reduce often associated offensive odors by promoting aerobic conditions through decreasing the amount of oxygen required to maintain aerobic cultures and/or aerobic biological activity in the wastewater. Also, the wastewater is screened or otherwise separated the wastewater to remove or concentrate the solids which are anaerobically digested. By concentrating the solids, a smaller digester can be used. The anaerobic digestion produces biogas that may be collected and used, or burned by a flare or oxidized by a semipermeable membrane to deodorize the biogas. The heat produced from the biogas may have a variety of uses, including raising the temperature of the anaerobic digester and the bacterial metabolism. The wastewater is also clarified to remove nitrogenous and organic carbon wastes. | ||||||

| 134 | Method for optimizing flotation recovery | US09359262 | 1999-07-22 | US06390303B1 | 2002-05-21 | David William Clark; Billy Kim Fung Chan; Rustam H. Sethna; Peter L. Fleming; Jason Simon Tullai |
| A method for optimising a mineral recovery process. A slurry 10 is fed to a conditioning step 20. The condition slurry 30 is then provided to a flotation circuit 40 to recover a concentrate 50. The remainder of the slurry is then rejected as tail 60 or passed for further processing. The present invention provides apparatus for analysing a sample stream 100 of the slurry. A sample stream 100 is provided to an analysis device 200 which treats the sample with an oxidising gas similar to the oxidative treatment 20. Several parameters are measured before and/or after the oxidative treatment of the slurry. The flotability characteristic of the slurry is then determined as a function of the measured parameter(s). The result is used to optimise mineral recovery. This apparatus can be used intermittently or continuously to provide on-going optimisation of the mineral recovery circuit. | ||||||
| 135 | Dore slag treatment | US334897 | 1981-12-28 | US4404022A | 1983-09-13 | Peter W. Godbehere |
| A method is disclosed for treating dore slag resulting from smelting of a dore furnace charge, by grinding such slag and then subjecting the obtained pulp to froth flotation in the presence of a suitable frother and collector to produce a precious metals concentrate which is then filtered and returned to the dore furnace with the next charge. The tails from the froth flotation may then be finely ground and subjected to several additional flotation stages to improve recovery of the precious metals, and the entire operation is preferably carried out as a closed loop process so that only the tailings from the rougher flotation are removed and shipped to the smelter. | ||||||

| A system for reconditioning soils contaminated with crude oils or other refined petroleum products. The system comprises a mixer input device for mixing and heating the soils with a liquid and providing a heated blended slurry. A sparger kiln agitates the slurry to break down its component parts into a fine particle slurry. A first clarifier washes the fine particle slurry to effect a first separation of oil particles from the slurry. A network of flotation cell units further wash and agitate the fine particle slurry from the clarifier to effect a second separation of oil particles from the fine particle slurry. A reagent is added to the flotation cells to effect the oil separation. An aeration clarifier further separates the oil particles from the liquid mixture elected from the flotation cell units. A collecting system is provided to recover the oil particles separated from the first clarifier and the aeration clarifier. | ||||||

| An apparatus and a method for concentrating an ore to recover valuable minerals from the ore is disclosed. The apparatus is based upon flotation separation techniques and comprises a trough into which is fed a slurry of ore particles which have been conditioned with a flotation reagent. The trough has a side extending outwardly forming a downwardly sloping flat table. The slurry of conditioned ore particles flows out of the trough and downwardly along the sloping table. Positioned along the sloping table is a disperser for dispersing larger particles up and into the slurry, which larger particles are generally along the surface of the sloping table. The sloping table is equipped with at least one aerator positioned along the flow path of the slurry, downstream of the disperser which aerates the conditioned ore slurry. The particles coated with the flotation reagent form agglomerates with gas bubbles produced by the aerator. These agglomerates float at a higher level within the slurry than the non-coated, non-agglomerating ore particles. A splitter is positioned near an open end of the sloping table. The splitter height above the surface of the sloping table is adjustable for intersecting the conditioned ore slurry at differing levels. The splitter separates the agglomerative, coated particles floating at a higher level from the non-agglomerative, non-coated particles floating at a lower level in the slurry. | ||||||
