TalkIron ore Jump to These large tailings basins pose future environmental problems rather than on the business of ore itself (geology, deposits, problems of recovery, preparation, etc., etc.). I'm all for a holistic approach, but you still have to draw the line somewhere. Also my favourite quibble, I admit the English could be
of ore minerals enables greater recovery in traditional circuits designed for magnetic recovery. 5. Conclusion Hydrus Technology has developed the technology to recover a higher proportion of the valuable components present in tailings by changing characteristics of the contained minerals using electrochemical means.
The course ore deck is designed for recovering particles size from 0.5 mm to 2 mm; . and tailing side, and then divided into the concentrates, middling's and Tailings.
For example, a tailings stream in an iron ore application could be thickened to 4550% solids Newtonian slurry in conventional or highrate thickeners. Conversely, the same tailings stream could be thickened to 6570% solids nonNewtonian suspension using a
In 1950, Benson Mines at Star Lake, New York was the largest open pit magnetite iron ore mine in the world. In 1978, when Benson Mines closed, 470 people lost their jobs. During the operation of the mine large amounts of tailings were dumped in the area surrounding the mine.

Maximizing the recovery of fine iron ore using magnetic separation Most iron ore operations that require beneficiation of ROM ore to produce lump, fine (sinter), and pelletizing concentrate iron ore products will discard a slimes fraction to final tailings. This fraction can vary in particle size from 200 181;m down to 10 181;m.
Paste thickening optimizes tailings disposal and water recovery Mine tailings disposal, and its impact on water usage, is an important concern for any mining company. is an important concern for any mining company. The challenge today, whether extracting aluminum, zinc, gold or iron ore, is how to dispose of tailings material

Iron ore tailings containing around 4860 % Fe are generated from the iron ore washing plants and are disposed into tailing ponds without any further utility. These tailings in the form of slimes are not suitable for iron making due unfavorable granulometry, presence of higher amount of gangue constituents.
It is clear that a + 62% Fe can be attained with overall Fe unit recovery at around + 80%. With as received sample test work LIMS magnetics has an average Fe 64.53%, silica 5.70%, amp; alumina 1.12% with mass yield of 54.28%. The average Fe recovery in the magnetics is 83.33%.
