About Rainbow:

Rainbow Rare Earths aims to be one of the lowest cost suppliers of critical rare earth raw materials in the western world supply chain. Advancing two core projects, Phalaborwa in South Africa and Uberaba in Brazil in partnership with The Mosaic Company, Rainbow is one of the most advanced market participants pursuing secure, near-term and globally competitive upstream supply of rare earths products crucial for industrial, energy transition, and defence applications. 

With a unique project portfolio focused on the recovery of rare earth elements from phosphogypsum, a by-product of fertiliser production, Rainbow's projects avoid traditional mining and front-end processing stages. This represents a significant competitive advantage in bringing sustainable, long-life and low cost supply of rare earths to market.
