The present invention is directed towards an apparatus and methods for a precise, fast and easy to use manipulation of beads. This method is particularly useful to carry out separation between the beads and the remaining supernants present in the fluid, maximizing the collection and purification efficiencies in tips for liquid handling.

The present application relates to a concentration process of iron minerals from ultrafine tailings (slimes) from iron ore processing through reverse flotation with pH between 8.5 and 10.5 with the addition of amide-amine type collector, or further a mixture thereof with traditional cationic collectors (amines), in the absence of any depressant, alternatively including a step of high field magnetic concentration, which allows to obtain a concentrate with iron content higher than 66% and contents of SiO2+Al2O3 below 4%.

A skimmer for removing a layer of oil floating on a surface oil contaminated water which subsequently concentrated and separated in an oil water separator which removes tramp oils or other fluids, such as hydraulic oils, with specific gravity less than that of the operating fluid are required to be removed from operating fluid such as water, lubri-coolants or other liquids. The skimmer supplies concentrated oil water composite fluid to a separator apparatus designed for use in industrial applications in which unwanted tramp oils or other fluids, such as hydraulic oils, with specific gravity less than that of the operating fluid are required to be removed from operating fluid such as water, lubri-coolants or other liquids.

A defined mineral phase is separated from a ground ore having several chemical phases and being present in a heterogeneous particle size distribution by classifying the ore according to a defined particle diameter into at least two fractions, a first fraction having particles essentially larger than the defined particle diameter and a second fraction having particles essentially smaller than the defined particle diameter, and the defined mineral particles of value being present in both fractions, floating the first fraction having the greater particle diameters and selecting the defined mineral particles of value in a flotation concentrate, selectively admixing the defined mineral particles of value in the fraction having the smaller particle diameters with magnetizable particles, applying a magnetic separation process to the second fraction having smaller particle diameters, and separating a concentrate with an enrichment of the defined mineral phase of value.

A method is provided including coupling magnetic beads to a population of cells in a fluid sample to form magnetically-labeled cells, magnetically separating the magnetically-labeled cells from non-magnetically-labeled cells in the fluid sample, and separating target cells from non-target cells of the magnetically-labeled cells based on a size difference between the magnetically-labeled target cells and the magnetically-labeled non-target cells. A microfluidic device is provided including a fluidic pathway traversing a magnetic isolation region and a size-based isolation region. The magnetic isolation region includes a magnet positioned to separate magnetically-labeled cells from non-magnetically labeled cells in the magnetic isolation region. The size-based isolation region includes a separator configured to separate cells less than a threshold size from cells greater than a threshold size.
