The optimum conditions of Titanium Recovery process from the Iraqi Bauxite Ore

The present work is especially concerned with the Iraqi bauxite ore that includes 4.1% of titanium element (Ti). goal this study to investigate effect various parameters (concentration acid, ratio solid: liquid, stirring speed, contact time, and temperature) in order determine best conditions for leaching extraction element. All tests were conducted different acids (HNO3, H2SO4, H3PO4) a liquid from (1: 100) 8), temperature reaction (25°C) (50°C), period time (30 min) (120 min), speed (400 rpm) (1200 rpm). determined at ratio, (50°C) temperature, (4 M) HNO3 concentration, (900 speed. While, was leached solution by (trioctylphosphine oxide) (TOPO), tri-n-butyl phosphate (TBP), di-2- ethylhexyl phosphoric acid (D2EHPA) dissolved kerosene) an organic/aqueous (1/1, 1/2, 1/3, 2/1, 3/1); are correspondingly (55°C) (8 (15 obtained when using (50%) TOPO (1/3) O/A ratio.
