Lowcost, easytouse cell concentration tools are in urgent demand for biomedical diagnosis in resourcepoor settings. Herein, we propose a novel inertial microfluidic syringe cell (IMSC) concentrator that employs inertial focusing to increase cell concentration through ordering the cell and removi .

Final concentrates of the tests were evaluated in a sizebysize manner. Recovery on a. spiral has been shown to increase with an incr ease in particle size up to a poi nt (200 µm) where it is ...

MontWright Mine is one of the most important assets of ArcelorMittal in the world, producing 26 million tons of concentrate per year (through spiral concentrators circuit) with iron grade higher than 66% Fe. On the other hand, 45 million tons of tailings are discarded every year with no additional treatment. Despite this, it is possible to observe a small quantity of iron oxides in the ...

The spiral concentrator is a modern highcapacity and lowcost device. It is developed for concentration of lowgrade ores and industrial minerals in slurry form. It works on a combination of solid particle density and its hydrodynamic dragging properties. The spirals consist of a single or .

2007; Benasa, 2007, and Mathew et al., 2008), spiral concentrators have the ability to achieve effective separations for particle size fraction of less than 150 µm down to 45 µm. The objective of this study is to evaluate the effectiveness of inplant ultrafine spiral concentrators for cleaning ultrafine coal at size interval of 150µm+44µm.

 · Spiral concentrators are devices to separate solid components in a slurry, based upon a combination of the solid particle density as well as the particle's hydrodynamic properties ( drag). The device consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to extract solid particles that have come out of suspension.

Spiral concentrators are one of the most common gravity processing methods extensively used for the concentration of mineral based on their density, particle size and shape.

 · Spiral concentrators are preferred density separation equipment for processing finesized particles; typically, finer than 2 mm but coarser than mm. Their operation is straightforward, with low capital and operating expenditure. In India, they are used to process iron ores, chromite ores, beach sand minerals, coal, etc.
