Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of water and flushed away. The iron ore magnetite, Fe 3 O 4, is ferrimagnetic. It can be separated from abundant deposits of taconite by grinding to a ...

iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.

The density of manganese oxide ore is generally about ~/m3, which is significantly different from silicate type gangue. Commonly used gravity separators include mineral jigs, shaker table, cyclones, chutes, and the like. The density of manganese carbonate ore is ~/m3, which has a small difference from the density of gangue.

Iron Ore Beneficiation Process Flow. One popular beneficiation method is mechanical crushing and screening, which involves breaking down large chunks of ore into smaller pieces and separating them based on size. This method is particularly effective for lowgrade ores where the iron content is not very high.

Hematite and magnetite are the most prominent iron ores. Most of the highgrade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− + mm) and fines (approximately − mm) products.
