positive selection with macs technology minimizes unwanted effects on target cells the high magnetic gradient generated by the matrix in the macs column allows for minimal labeling of target cells with nano-sized microbeads. this ensures that plenty of surface epitopes remain free for subsequent fluorescent staining and flow cytometry analysis.

the dry magnetic separator can be divided into strong magnetic field magnetic separator and weak magnetic separator according to the strength of magnetic field. the reason why the magnetic intensity is different mainly because of the different magnetic sources, the magnetic separator is mainly used in the ore dressing production.

magnetic separator also can separate non-metal ores two types of magnetic drum separators magnetic drum separator can be divided into two types: one is dry magnetic separator, the other is wet magnetic separator. the dry magnetic separator is designed for material with 2 to 200 millimeters which is in dry or nearly dry state like crushed iron ore.

in a dense media separation (dms)/ heavy media separation ( hms) plant, powdered ferrosilicon (an alloy of iron and silicone) is suspended in water to form a fluid near the density of diamond (3.52 g/cm3), to which the diamond-bearing material is added to begin the separation process of the heavier minerals from the lighter material.

dry vibrating magnetic filters eriez unique vibrating magnetic filter incorporates vibrating filter elements to provide a high capacity material flow. as the material flows through the magnetized elements, the iron bearing contaminants are captured, resulting in a high‑purity product.

low-intensity separators are used to treat ferromagnetic materials and some highly paramagnetic minerals. minerals with ferromagnetic properties have high susceptibility at low applied field strengths and can therefore be concentrated in low intensity ( ~0.3t) magnetic separators. for low-intensity drum separators used in the iron ore industry, the standard field, for a separator with ferrite ...

there are two types of dry low-intensity magnetic separator. 1. use suspended magnets, magnetic pulleys and plate, and grate magnets to remove iron and strong magnetic impurities. 2. the magnetic drum is mainly used to concentrate the valuable components of strong magnetism. wet low-intensity magnetic separators.

dec 20, 2019 magnetic separation is realizing the mineral processing according to the magnetic differences between minerals from magnetic and other mechanical force. at present, it is used in the processing of ferrous metal and non-metal, and the fine processing of non-ferrous metal and precious metal. to be brief, the working principle of magnetic ...

during separation, the magnetically labeled cells are retained within the column, while unlabeled cells flow through. after a washing step, the column is removed from the magnetic field of the separator, and target cells are eluted from the column. positive selection can be performed by direct or indirect magnetic labeling.

aug 09, 2019 the dry magnetic separator generally does not need a tank for accommodating the slurry, and the material is conveyed by a vibrating feeding device, and a dustproof device is often provided. the wet magnetic separator has a tank to accommodate the slurry to maintain the fluidity of the material, and the pump is usually transported by a slurry pump.
