beneficiation of ilmenite by selective leaching

Jan 01, 2020 Reactivity of ilmenite improved, low iron leaching. b. Fast leaching, rapid impurities dissolution, recovery of rutile for chloride process. c. High Ti recovery. a. High energy consumption. b. High Fe leaching, filtration problem, rapid hydrolysis. c. High temperature and conc. Acid requirement, release of toxic gases on H 2 SO 4 decomposition
