On-Site Speaker (Planned) M.A. Halim
Abstract Scope Rare earth elements (REE), nickel and cobalt find their use in developing strategic materials and their demand is consistently increasing in the world while the extractable ores of these metals are gradually depleting. Process Research ORTECH Inc. (PRO) has developed innovative mixed chloride leaching processes for the recovery of REE from alumino-silicate ores, and nickel and cobalt from laterite ores. The addition of magnesium chloride in hydrochloric acid enhances the activity of the hydrogen ion by orders of magnitude, which permit rapid leaching rates at moderate temperature and atmospheric pressure, along with high metal recovery. Innovative solvent extraction process steps are used for separating these metals from pregnant leach solutions. PRO processes also produce value added by-product of high purity iron oxide and recycle chloride lixiviant to the leaching stage. This paper will describe the leaching and separation reaction mechanisms and potential process flowsheets.
