The process of removing phosphorus from iron ore linked to the concept of selective agglomeration is well grounded in the work of Sirianni et al.. Sparks and Sirianni (1974) applied the technique to remove the iron ore’s phosphorus from Snake River, northern Canada. The content of phosphorus was in the range of 0.34% unacceptable for steel ...

Earlier work with iron ore and iron ore fine/slime indi-cates that beneficiation of iron ore and fine/slime containing very low iron and high alumina and silica is quite difficult. Also, it is equally difficult to know the characteristic proper-ties of the particles where most of the population is below 50 micron.

The processing of iron ore requires physical processes that help ensure conformation to sizing specifications and where required help the ore achieve grade targets. The sizing separation of iron ore is achieved through the comminution and screening processes described in Chapter 8. This chapter is concerned with the further physical separation ...

Available world iron ore resources. Iron is the most abundant element on earth but not in the crust. [citation needed] The extent of the accessible iron ore reserves is not known, though Lester Brown of the Worldwatch Institute suggested in 2006 that iron ore could run out within 64 years (that is, by 2070), based on 2% growth in demand per year.

Probably the biggest financial failure of Edison's career was the magnetic ore-separator. The idea, which Edison's laboratory experimented with during the 1880s and 1890s, was to use magnets to separate iron ore from unusable lower-grade ores.
