Reducibility Study of Egyptian Ilmenite Ore Briquettes and Powder with Coke Breeze at 800–1100°C

Abstract

Ilmenite ore fine and coke breeze as reduced material briquetted with different amounts of organic materials such as molasses or pitch were studied in this investigation. The produced briquettes in reasonable conditions were reduced in a nitrogen atmosphere at a temperature range of 800Á11008C to determine the factors controlling the reduction and to determine the controlling mechanism. Also ilmenite ore fines with coke breeze were reduced at the same temperature range in a nitrogen atmosphere without the briquetting process, for comparison.

Kinetic Study of Formation of Sodium Titanets by Roasting of Soda Ash and Ilmenite Ore Concentrate

“…X-ray diffraction analysis of Rosetta ilmenite ore concentrate is shown in Fig. 1 Rosetta ore concentrate mainly consist of ilmenite Fe 2 TiO 3 , pseudo-rutile Fe 2 Ti 3 O 9 , hematite Fe 2 O 3 and a minor quantity of rutile [11,12].…”

Sodium Titanates Formation by Roasting of Pellets or Powder Mixture of Soda Ash and Rossetta Region Ilmenite Ore Concentrate in Air

“…The composition of Rosetta ilmenite ore concentrate contains about 43.6% TiO 2 , 27.5% FeO and 20.9% Fe 2 O 3 . X-ray diffraction analysis of Rosetta ilmenite ore concentrate is shown inFigure 1, which indicated that the phases composing Rosetta ore concentrate mainly consist of ilmenite Fe 2 TiO 3 , Pseudorutile Fe 2 Ti 3 O 9 , hematite Fe 2 O 3 and a minor quantity of rutile according to the work which present in literatures[25] [26].…”

The Effect of Adding El-Dekhilla Waste Pellets Upon The Quality and Reduction Kinetics of El-Baharia Iron Ore Briquettes Using Hydrogen Gas

“…Reduction of the prepared briquettes under hydrogen gas was done using TGA apparatus [13][14][15][16][17][18][19]. The sample was placed in a Ni-Cr basket, which was suspended below the electronic balance by Ni-Cr wire.…”
