METHOD FOR PROCESSING ILMENITE-CONTAINING MINERAL MATERIALS WITH HIGH CLAY CONTENT, AND RELATED PRODUCTS

摘要

A method to process ilmenite-containing mineral material with high clay content includes processing involving settling velocity separation to prepare a first ilmenite concentrate followed by processing involving magnetic separation to prepare a second ilmenite concentrate. Settling velocity separation may include differential settling separation primarily for removal of clay and silica fines followed by elutriation for removal of coarse silica and additional fines. Also provided are high quality ilmenite concentrate products and slag products including low concentrations of problematic contaminant materials.
