Gravity concentration, or densitybased separation methods, declined in importance in the first half of the twentieth century due to the development of froth flotation, which allowed for the selective treatment of lowgrade complex ores. They remain, however, the main concentrating methods for iron and tungsten ores and are used extensively for treating tin ores, coal, gold, beach sands, and ...

The gravity method has played an increasingly important role in the search for new reserves of Fe ores since the development of highly portable gravimeters capable of a high degree of precision. This method has been used in the search for and study of direct shipping ores, but it has proven to be especially useful in the study of large tonnage, wide, near surface "taconite type" ore bodies ...

GRAVITY CONCENTRATION OF IRON ORE R. K. Rath and R. Singh INTRODUCTION Gravity concentration process is the oldest beneficiation method known to mankind. This is a physical process and exploits the differences in densities of minerals to bring about a separation. Although with the advent of froth flotation, the relative importance of gravity concentration has .

Separator (FDS), a gravity device which can be operated for size classifiion and/or relative density separation. The objective was to produce highquality iron ore material suitable as sinter feed. An iron concentrate with a grade around % Fe (Calcined Fe of about %) was achieved while recovering around % of the feed weight. In addition, a rejection of substantial content of ...

· The concentrate collected from the middlings and tails after spiral gravity separation has a lower iron concentration (magnetite) so it must be further concentrated to achieve the customer's 65% Fe concentration. It is immediately directed to a magnetic separator circuit. Magnetized drums collect magnetic material, so it can be further concentrated (magnetite iron minerals content). The ...

ore by gravity concentration or flotation even though a low manganese recovery may be acceptable. The poor metallurgical results were due to the reasons mentioned above and because the ore contained an appreciable percentage of iron oxides. Iron oxides and manganese oxides have very similar physical and chemical properties and therefore cannot be separated satisfactorily by gravity ...
