flowsheet development for the extraction of rare earths . - MintekLeaching of the resulting slag was found possible and most efficient in hydrochloric acid amongst other lixiviants tested. KEYWORDS. Direct smelting, Extraction, Hydrochloric leaching, Iron rich rare earth bearing ore, PyEarth, Rare earth. COM2017 | THE CONFERENCE OF METALLURGISTS hosting World Gold & Nickel.A New Process for Cobalt – Nickel Separation - TeckMay 25, 2010 . The process uses synergistic solvent extraction (SSX) with commercially available reagents, but in a novel and efficient manner using kinetic factors. It is applicable to dilute nickel leach liquors containing high levels of impurities such as magnesium and manganese. It therefore allows the separation of.
