Process Of Ilmenite And Silica Magnetic Separation China An ore of magnetite and ilmenite may however employ wet magnetic separation to remove magnetite and all flotation for recovery of the ilmenite in a high grade product In this case all the gravity collect in the concentrate launder The rest of the ilmenite will report in the middlings and in the tailings It would seem that separation would be best at 30 Hz because ample time would be allowed for ilmenite and silica to separate extensively The Aim of The Experiment The aim of the experiment is to investigate the e ect of set operating separation to produce an ilmenite concentrate for hydrometallurgical testing The beneficiation process resulted in three final products high silica tailings magnetitetitanomagnetite concentrate and ilmenite concentrate The ilmenite concentrate was found to have the following chemical assay 389 TiO 2 311 Total Fe 64 SiO 2
