Rainbow Rare Earths Ltd - Guernsey-based mining company - Confirms successful development of rare earths extraction flowsheet from the phosphogypsum stacks at its Phalaborwa Project in South Africa. The process was developed in collaboration with K-Technologies Inc, following test work at ANSTO Minerals, Australia, and K-Tech's facilities in Florida.
Chief Executive Officer George Bennett comments: ‘Working closely with K-Tech, we have been able to identify and confirm a novel process which will allow us to recover valuable rare earth oxides in a low capex and opex manner from phosphogypsum. We are now in the process of jointly patenting this intellectual property with K-Tech and believe it will allow us to secure additional rare earths opportunities, such as the previously announced collaboration with a major chemicals group in South Africa.’
