At present iron and steel industry has entered into the developing period in china, the demond of iron preparation concentrate increases year by year, on the other hand, iron ore face to the shortage after having exploited for several years. So the development of domestic resources rationally is very urgent Recentaly year, the application of new technic,new agentia, new equipment, it is useful for the development of difficult ore dressing of red ore.
Suniteyouqi red ore of Mongolia belongs to hematite acid ore. Minreal compose is very complicated. The particles of useful minerals and non-useful minerals are thinnergenerally, it is difficult processing ore, reserves of iron ore is over I billion ton, its exploit have certain character.
After the technology of gravity treatment-intense magnetic un-folatation dressing ,We can gaine the fitst hematite concentration by this flowsheet, the quality of which is as follows: TFe grade 64.50%, recovery 32.26%, and we gained the second hematite concentration. TFe grade 61.03%, recovery 41.77%. They separately reach to the first national quality standard and the second national quality standard The overall recovery of iron is 74.03%, reach the aim of sufficiently use resource.
So we make the contrast of two flowsheets, the first one is gravity treatment-intense magnetic -un-flotation dressing,its advantage is that the cost of gravity treatment is very lower and cut down the expense of intense magnetic machine in early days.the second is intense magnetic-gravity treatment-un-flotation dressing, this plan makes intense:manetic machine lose tailing ore at first, at the same time this plan provides assurance of the iron concentrate reaching the quality standard and reduces the whole quantity of tailingore, we decide it is the best flowsheet for the second by the quality of iron concentrate.
By economic valuation of mineral processing flowsheet of iron,ifwe build a hematite plant, economic benefit is very good.
