02/01/2012· In general, phosphorus is considered as a gangue mineral in iron ore because it makes steel brittle. High levels of phosphorus in iron ore attract a penalty and reduces the profit margin substantially. The mineralogy of phosphorus in iron ore depends on the type of iron minerals.
Ore mine gangues which are industrial wastes can act as potential sources of industrial materials. Typical iron ore minerals may contain antimony, arsenic, beryllium, cadmium, chromium, copper, lead, nickel, as well as silver and zinc. The economic viability of these metals would depend on

The small fraction of zinc sulfide minerals present in the ore makes beneficiation necessary in order to produce a concentrate suitable for treatment. Themon method forplishing this concentration is to isolate the sulfide mineral from the impure constituents, or gangue, by flotation separation. In this process, the ore initially is crushed to about 1.9 centimetres 0.75 inch
A recent concern is the limited reserves and the rapid depletion of high grade iron ore, which is utilized in the ironmaking process, due to an increase in steel demand in emerging countries. In addition, high grade orees higher in gangue Si, Al, and P and lower in Fe contents, year by year.
