04/01/2007· Most iron ore processing in the fine particle ranges is carried out on a wet basis. The alternative is dry magnetic separation, but many laboratory tests have shown that it is not as efficient as wet magnetic separation in the fine particle ranges. However, some iron ore resources are located in dry areas where adequate water supply is very difficult to obtain and hence dry processing is the ...

The cement industry has for some time been seeking alternative raw material for the Portland cement clinker production. The aim of this research was to investigate the possibility of utilizing iron ore tailings (IOT) to replace clay as alumina-silicate raw material for the production of Portland cement clinker. For this purpose, two kinds of clinkers were prepared: one was prepared by IOT; the ...
