Effect of B2O3 Content on the Sintering Basic
The sintering basic characteristics of iron ore play a key role in the process of sintering. In this study the effects of B 2 O 3 on the assimilation characteristics softening temperature fluidity of liquid phase compressive strength of bonding phase and microstructure of the mixed fine powder of hematite and vanadium-titanium magnetite (H-VTM) are studied. Iron sand which is a magnetite-ülvospinel solid solution 8) is the most important titania-magnetite ore type. The direct reduction of iron sand is very slow needs high energy and has a narrow processing temperature window. 8 9 ) Titaniferous magnetite ore is usually very fine and therefore added to the sinter mixture rather than a

Vanadium Resources in Titaniferous Magnetite Deposits
technology of vanadium recovery from titaniferous magnetite ore and the productive deposits are briefly magnetite ore or a magnetite concentrate of the ore by either of two general processes. In one process the ore or concentrate is mixed with a sodium salt and roasted which yields a water-soluble sodium coproduct iron titanium and process staging. Similarly for titanium extraction an organic mixture was tested to prepare isotherms for pilot plant operation. Using the data produced during the bench-scale test program equipment was setup and solutions were prepared to operate a continuous counter-current process for the extraction of iron and titanium.
