IN BRIEF: Rainbow Rare Earths starts pilot works at Phalaborwa plant
Rainbow Rare Earths Ltd - developer of the Phalaborwa rare earths project in South Africa and the Uberaba project in Brazil - Stock rises after the company announces the start of pilot-scale operations as the final phase of process test work for Phalaborwa. Includes primary flowsheet pilot operations in Johannesburg and delivering the bulk feed sample for off-site solvent extraction test work, confirming the process to deliver separated neodymium and praseodymium oxide and SEG+ products at over 99.5% purity. The SEG+ group is a mix of medium and heavy rare earths.
