Leaching and kinetics studies on processing of Abu Ghalaga ilmenite ore
Abstract Agitation leaching technique for upgrading Abu Ghalaga ilmenite ore for wide range of applications and major demands has been studied. Experiments of leaching and dissolution kinetics of ilmenite ore using hydrochloric acid have been carried out. The effect of variable parameters; acid concentration, particle size, solid liquid ratio, agitation speed, temperature, and time leaching were studied. The study results showed that the leaching rates were highly affected by increasing hydrogen ion concentration. Under the optimum condition, synthetic rutile assaying93% TiO2 was obtained from an ilmenite ore assaying of about 37% TiO2. The kinetics of reaction was found fit to the diffusion reaction model. The activation energy was calculated 17.607 KJ/mol.
