ERMS Enhanced Roasting Magnetic separation-also known as Ernie's Reductive Magnetic Separation
ERMS Enhanced Roasting Magnetic separation-also known as Ernie's Reductive Magnetic Separation : A process for beneficiating ilmenite, yielding an off-white product containing more than 99 percent of TiO2. The ilmenite is roasted in a fluid bed, leached with hydrochloric acid, and beneficiated by dry magnetic separation. The acid is recycled by the EARS process. The product can be used as a chloride-process feed material, or as a lowgrade pigment
