A method and apparatus for removing magnetic beads together with molecular targets of interest from a fluid is described. A consumable bead collection probe is placed in a vessel containing magnetic beads suspended in the fluid. A magnet outside the vessel concentrates magnetic beads on a surface of the collection probe so they may be manipulated in and out of vessels during washing or processing steps without transferring the fluid into or out of a vessel. In a further embodiment, a vibrational source is attached to the collection probe such that, in combination with the magnet in a position external to the vessel, beads may be washed without releasing them from the collection probe.

Methods of reducing copper metal content of shredded scrap steel are provided. The method includes continuously separating a first scrap steel fraction from an amount of scrap steel concurrently with separating a second fraction from the amount of scrap steel; continuously separating the second fraction and providing a nonmagnetic fraction and, concurrently, a third scrap steel fraction; grinding the nonmagnetic fraction followed by magnetic separation to provide a fourth scrap steel fraction and, concurrently, an enriched nonmagnetic fraction; continuously combining the first scrap steel fraction, the third scrap steel fraction, and the fourth scrap steel fraction to obtain a combined scrap steel product comprising scrap steel with reduced copper metal content; and introducing the combined scrap steel product to an electric arc furnace. Systems of reducing copper metal content of shredded scrap steel are also provided.

A filter for treating a fluid in a piping of a heating and/or cooling system, in particular of domestic and/or industrial type, includes: a main body internally having at least one chamber, a first mouth and a second mouth respectively comprising a first duct and a second duct allowing the fluid to enter and/or exit the at least one chamber, wherein the first mouth has a first longitudinal axis and the second mouth has a second longitudinal axis, in particular the second mouth being positioned on the main body in such a way that its second longitudinal axis is substantially perpendicular to the first longitudinal axis of the first mouth; a filtering element for treating the fluid, housed at least partially in the chamber, in particular the filtering element having at least one magnetic element adapted to intercept and trap the ferrous impurities that are present in the fluid to be treated.

A system and process for sorting and recovery of recyclable materials, and in particular, sorting and recovery of recyclable materials from mixed waste comprising municipal solid waste in a materials recovery facility.

The system extracts water from lunar regolith and includes a regolith intake having a digging bucket that collects lunar regolith soil and a gravel separator that separates and discharges gravel and passes a mixture of ice-regolith powder having ice grains that are about 10-100 microns along the conveyor. A pneumatic separator receives the ice-regolith powder and pneumatically splits the ice-regolith powder into streams of different sized lithic fragments and ice particles per the ratio of inertial force and aerodynamic drag force of the lithic fragments and ice particles. Each split stream may include a magnetic separator that separates further the magnetic and paramagnetic lithic fragments from ice particles to discharge up to 80 percent of lithic fragments to slag.

A method for operating and diagnosing faults in a laboratory instrument comprising a plurality of subsystems may comprise performing an analytic sequence and a set of diagnostic steps. Such a method may be performed using a diagnostic reagent comprising paramagnetic particles and lacking an antibody component. Such a method may also include evaluating a set of the instrument's subsystems in the opposite of the order in which those subsystems are used during analysis.

The disclosed is a method for producing a carbon material dispersion which removes efficiently and reliably metallic components from carbon materials, and that provides a carbon material dispersion of a high product quality and stable electrical properties. The method comprises a first magnetic separation step in which the powdered and/or granulated carbon material C is applied to the surface of a rotating magnetic roll 130 to remove the metallic component M from the carbon material in the dry state of the powdered and granulated carbon material C; and a second magnetic separation step in which a magnet element 310 is placed in a carbon material dispersion D, in which the carbon material from which the metallic component has been removed in the first magnetic separation step is dispersed in a dispersing medium, in advance of the second magnetic separation step.
