IRON ORE BENEFICIATION WITH PACKED COLUMN JIG

2012-06-19 06:17:42 (читать в оригинале)

During the previous few decades, low-grade finely disseminated iron ore deposits have become the most sources of raw iron material in several countries. New technologies should be developed that achieve sharp separation at high throughput capability, particularly when treating very fine materials. These technologies should conjointly maintain or improve current standards in more economic and environmentally engaging ways that.

Magnetic separation and flotation are the foremost widely accepted technologies for upgrading fine iron ore particles, however each processes end in iron concentrates with high amounts of terribly fine and/or interlocked silica particles. Gravity separation is a standard process employed in iron trade, however the separation potency becomes unacceptable with finely disseminated materials

In recent years, many advanced technologies are developed to boost the separation of finer materials. Sharper separation is feasible beneath dynamic conditions and/or in multistage processes. Dynamic separators are able to do sharp separation, however they're usually complicated and expensive to take care of owing to moving elements. Also, scale -up possibilities haven't been utterly proven (Sandvik and Rein, 1997). Multistage processes are energy intensive and tough management} and control.

Being single stage separators, packed columns (Yang, 1996) will replace multistage processes in flotation and gravity separation; additional development into several different applications is foreseeable. as an example, packing material is employed for generating microbubbles in flotation and also the packed device is additionally used as a Lamella thickener. Packed Column Jig (PCJ) could be a gravity separator and operates sort of a teetered bed separator (Nicol, 1998), however the interior packing and a pulsating water flow permits higher throughput capability and sharper separation. Packing conjointly limits the turbulence and vorticity that takes place in every cell, therefore avoiding short-circuiting of coarser particles, and ends up in successful operation with fine particles extending the dimensions vary right down to a couple of microns in diameter. PCJ doesn't need reagents to work, encompasses a higher capability per unit cell volume than its competitors, offers sharp separation between iron ores and silica or different impurities, and is well scaled up
