Abstract
1314558 Removing Fe from Ti minerals SACHTLEBEN AG FUR BERGBAU UND CHEMISCHE INDUSTRIE 10 Dec 1970 [11 Dec 1969] 58814/70 Headings C1A and C1N Iron is removed from a finely divided uncalcined Ti-containing mineral by leaching at the boil with dilute H 2 SO 4 in the presence of a reducing agent, separating off the liquor, and repeating the process. After each leach, the suspension may be diluted and boiled to ppt. any dissolved Ti optionally with the addition of flocculants, e.g. polyethylene oxide or polyacrylates. The reducing agent may be Ti<SP>III</SP> sulphate, Fe scrap, Zn, Al, Mg, SO 2 , CO or " Longalite " (Trade Mark) and may be used in amount of 0À5-10% by wt. of the mineral. The H 2 SO 4 may be of 10-35% concn. and may be waste acid from Ti sulphate hydrolysis. The mineral may be ilmenite having a maximum particle size of 100 Á with at least 80% below 40 Á. The process may be carried out continuously in 2 series of leaching tanks (Ex. 4). FeSO 4 may be crystallized out from the filtrate and converted into Fe 2 O 3 , and mother liquor from the crystallization may be recycled to the leaching stage. The upgraded mineral may be used to make TiO 2 by the sulphate process.
