In at least one illustrative embodiment, an electromagnetic filter may include a transfer pipe and multiple electromagnetic filter elements positioned in an interior volume of the pipe. Each electromagnetic filter element includes a support comb, a solenoid coupled to the support comb, and multiple magnetic members arranged in a planar array positioned within an opening of the support comb. Each magnetic member may rotate about an end that is coupled to the support comb. The magnetic members may be magnetostrictive sensors and may include a biorecognition element to bind with a target microorganism. A method for fluid filtration includes coupling the electromagnetic filter between a fluid source and a fluid destination, energizing the solenoids of each electromagnetic filter elements, and flowing a fluid media through the transfer pipe of the electromagnetic filter. The fluid media may be liquid food such as fruit juice. Other embodiments are described and claimed.

A method, process or system for producing an iron oxide concentrate from a treatment slurry of a low grade mineral assemblage includes mixing a flocculant with the treatment slurry and dewatering the treatment slurry before passing the treatment slurry through a wet high intensity magnetic separator of a type that employs a flux amplifying matrix (i.e., a WHIMS-FAM device) and recovering an iron oxide concentrate fraction and a tailings fraction from the WHIMS-FAM device. Another method, process or system for producing an iron oxide concentrate includes passing the treatment slurry through a WHIMS-FAM device and recovering an iron oxide concentrate fraction slurry and a tailings fraction slurry from the WHIMS-FAM device; mixing a flocculant with the concentrate fraction slurry and dewatering the concentrate slurry to provide a thickened concentrate slurry before filtering the thickened concentrate slurry to provide a concentrate filter cake.

The present invention is a method for applying a gradient magnetic field to a paramagnetic supporting liquid containing a mixture of first particles and second particles to separate the mixture by particle type. A magnetic susceptibility of the first particles is lower than that of the liquid, and a magnetic susceptibility of the second particles is higher than that of the liquid. A gradient magnetic field is applied to the liquid in a separation tank provided with a magnetic filter and the liquid is stirred. The first particles float in the liquid by a magneto-Archimedes effect. A horizontal magnetic force acts on the first particles by the gradient magnetic field, so that the first particles travel to a region lateral to or outward from the magnetic filter and are gathered in the region. The magnetic filter is excited by the gradient magnetic field to catch the second particles.

A device for separating components of a mixture, particularly industrial fluids but also gases including air, allows for targeted components of the mixture to be attached onto a separating bar and removed from the mixture. The separating bars traverse a track formed within the body of the separating device and through respective tank, cleaning, free roll, and compression regions in a controlled cleaning system. The separating bars are detached from one another and allowed to move through the separating device independently of one another. The device removes the use of chains to connect cleaning bars traversing through a cleaning system.

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.
