Abstract: Disclosed are capsule/tube connector/tube assemblies that eliminate a connection point in a filter capsule apparatus. A relatively soft tube is thermally or sonically bonded to a relatively hard tube connector that may have a tube receiving bore, a frustoconical tube receiving channel or a straight tube receiving channel. The tube connector is bonded to a filter capsule port. The manufacturing process can be either a one-step process bonding the tube and capsule during formation of the tube connector in one step, or a two-step process that binds the tube to the tube connector in one step and binds the tube connector to a filter capsule port in a second step. Single and dual-walled tubes may be used as well as single and dual-walled tubes having reinforcing material superposed about or embedded in the tube wall(s). A tube support collar is also disclosed.

Abstract: A liquid filter arrangement is provided, as well as methods of assembly and use. Advantageous features, relating to a preferred filter cartridge and a preferred slide arrangement, are provided.

Abstract: Disclosed herein are methods and systems for recovery of ancylite, a rare earth mineral comprising strontium carbonate, from rare earth ore. In many embodiments, the disclosed methods and systems provide for recovery of greater than 50% of the ancylite from an ancylite containing ore. In many embodiments, the ore is subjected to flotation in the presence of an acid, for example a hydroxamic acid, such as octanohydroxamic acid. The ore may also be subjected to magnetic separation, for example wet high intensity magnetic separation.

Abstract: The descriptions relate to preventing assembly of a fluid filter apparatus unless a filter cartridge is installed, and preventing assembly of a fluid filter apparatus if the incorrect filter cartridge is installed. A mechanism includes cooperation of a movable member and a structure that can move the movable member to ensure that a fluid filter apparatus cannot be completely assembled, for example connecting its filter head to its shell, when there is no cartridge installed inside the shell or when there is an attempt to install an incorrect cartridge. This can protect from an inadvertent or intentional failure to install a cartridge (or correct cartridge) in the fluid filter apparatus.

Abstract: A separation system for separating solids from a slurry of waste material, the separation system comprising a housing, a drum assembly, and a drive assembly. The housing defines a collection chamber. Liquid within the collection chamber defines a liquid level. The drum assembly defines a perforated cylindrical wall and the drum assembly is supported such that at least a portion of the drum assembly is below the liquid level. The drive assembly rotates the drum assembly relative to the housing.

Abstract: A process for producing an iron ore having a sulfur content reduced to 0.08% or less, which includes a step of subjecting an iron ore containing sulfur in an amount of more than 0.08% and 2% or less to a flotation. The flotation satisfies any one of the following (1) to (3): (1) a xanthate-based compound and a salt of an amine compound are used as collectors, (2) a xanthate-based compound is used as a collector and a substance which releases a sulfur ion in water is used as an activator, or (3) a xanthate-based compound and a salt of an amine compound are used as collectors and a substance which releases a sulfur ion in water is used as an activator.

Abstract: A method for recovering at least one precious metal from an aqueous solution containing the metal and particularly to recovery of silver and optionally one or more other precious metals from overflow of a sedimentation unit such as a thickener, a clarifier or a pond includes subjecting the aqueous solution to a micro and/or nanobubble flotation, wherein the pH of the aqueous solution is at most 1.5.

Abstract: Provided are a method and apparatus for treating a feed stream for a flotation device comprising a mechanical agitator in a tank, the feed stream comprising solid particles. The method comprises generating microbubbles in a diluation water stream, mixing the diluation water stream with the feed stream to facilitate attachment of the microbubbles to the solid particles in the feed stream and generate bubbles for attachment to microbubble-attached solid particles, and fluidly connecting the feed stream to the flotation device. The apparatus comprises a feed stream conduit fluidly connected to the flotation device, a diluation water stream conduit fluidly connected to the feed stream conduit for conveying the diluation water stream to the feed stream, and a microbubble generator connected to the diluation water stream conduit for generating microbubbles in the fluid stream.

Abstract: A magnesium suppressant/flocculant for use in separating dolomite from calcium phosphate. The magnesium suppressant/flocculant may be applied at a mine site prior to subjecting ore fractions to phosphate flotation or at a chemical plant after grinding.

Abstract: The present invention relates to a process for the separation of at least one hydrophobic or hydrophobized material from a dispersion comprising said at least one hydrophobic or hydrophobized material and at least one second material. The process according to the present invention comprises the steps (A) to (D) which are described herein.

Abstract: Apparatus for removing suspended impurities from a liquid (e.g., wastewater), methods of use, and systems including such apparatus. In an embodiment, an apparatus may include a vessel defining a chamber for receiving gas induced liquid influent through an inlet, the influent including suspended impurities. A riser tube may be provided within the vessel, in fluid communication with the inlet so that liquid influent introduced into the vessel through the inlet is introduced into the riser tube. One or more coalescing members may be disposed within the riser tube. The coalescing members may be sufficiently small to be easily removable by hand, without requiring a crane. The coalescing members may be freely disposed within the riser tube, rotatable within the flow of the liquid influent, aiding the coalescing members in exhibiting some degree of “self-cleaning”, so as to be less prone to fouling and clogging.

Abstract: An attaching system for a filter cartridge may include: a top cap configured to attach to a filter cartridge; a mating projection located on the top cap; at least one locking projection projecting radially away from the mating projection; and a base portion defining an annularly shaped flat surface surrounding the mating projection on a first side and configured to attach to the filter cartridge on a second side. A method of attaching a filter cartridge to a filter assembly may include: providing locking projections on a top cap of a filter cartridge; locating a spring around a mating projection of the top cap; forming annular groove between the spring and the locking projections; and configuring the top cap to a portion of the filter cartridge.

Abstract: A dual stage filter assembly for use in a fluid cleaning and sludge removal operation, including a first stage separator incorporated into a first vessel and receiving a dirty fluid flow, a first stage clean fluid outlet extending from the first stage separator. A second stage filter is incorporated into a second vessel in fluidic communication with a dirty fluid outlet of the first stage separator for subsequent filtering and outflow through a second stage clean outlet. A flow restrictor is incorporated into said second stage clean outlet for controlling a flow rate through said filter in order to prevent clogging of the same by aggregating debris.

Abstract: A DAF skimmings separation system 10 that processes SPN/DAF skimmings 11 received from a meat processing facility to separate water and SPN-content solids includes a heating chamber coupled to a processor chamber having one or more pressurized discharge nozzles that expels DAF skimmings onto a spatter plate to cause SPN animal components within the DAF skimmings to break into smaller pieces denaturing the molecular structure and allowing the entrapped moisture to be evaporated within a heated airstream in the processing chamber, for separating nutritionally valuable SPN while reducing moisture content. A method of processing DAF skimmings to yield dryer SPN with reduced moisture content is disclosed.
