The thermochemical analysis further explained the influence of sodium carbonate on the liquidus of Na2O-SiO2-Al2O3 slag The improved process enables the complete reduction of the iron from weathered ilmenite to produce a high-grade rutile
Alteration starts on surface of grains and on cleavages and fractures Phases present in the altered material are ilmenite rutile and a new iron-titanium oxide named pseudorutile Final removal of iron from altered ilmenite occurs only in or above the zone of water
Aeration leaching was used to obtain synthetic rutile from a reduced ilmenite The reduced ilmenite obtained from the carbothermic reduction of ilmenite concentrate in a rotary kiln at about 1100 C contained 62 88% TiO 2 and 28 93% Metallic iron The particle
Secondly the iron is drawn out as hydrated iron oxide from the synthetic rutile grains and a mild acid treatment is used to dissolve the impurities and any residual iron The synthetic rutile grains are washed filtered dried and transported to white pigment manufacturing plants in
als and Rutile Ltd (CMRL) Kerala are producing SR by using above men-tioned technologies Various industrial wastes and by-products generated by these companies are presented in Table 3 It can be seen from this Table that removal of iron oxide from
The twinned rutile grew perpendicular to the iron bands consistent with fast solid-state diffusion of metal ions along the c-axis of rutile Although the metallisation within the individual ilmenite grams was crystallographically controlled and was in the form of bands the overall macroscopic reduction within the poly-granular ilmenite discs was of the shrinking core topochemical type
Rutile electrodes can be used to weld in all positions apart from vertical down position Deposition can be improved through the addition of iron powder which leads to more metal being deposited at the same current However electrodes with added iron powder
Fig 5 Effects of citric acid concentration on residual metallic iron in rutile In the case of acetic acid the increasing of acid concentration from 0 0% to 0 7% resulted in much faster rusting RMI was downed to 1 64% after just 2 hours

Alteration starts on surface of grains and on cleavages and fractures Phases present in the altered material are ilmenite rutile and a new iron-titanium oxide named pseudorutile Final removal of iron from altered ilmenite occurs only in or above the zone of water
Complete removal of iron from the pseudorutile lattice results in a grain composed of crystallites of the mineral rutile Only the three mineral phases ilmenite pseudorutile and rutile have been identified in the commercial titanium mineral concentrates studied
In the rutile beneficiation process magnetic separation is commonly used for the removal of magnetic minerals and the further purification of rutile coarse concentrates Magnetic separation equipment mainly includes SLon high gradient magnetic separator permanent magnet double roller magnetic separator SHP strong magnetic separator
Preliminary removal of interfering ions is carried out by means of an oxalate separation A simple and accurate absorption photometric method for determining a small amount of zirconium in iron and steel was devised the method employs pyrocatechol violet
