Greenland Minerals Ltd’s (ASX:GGG) optimisation test work for the Kvanefjeld Project in Greenland is progressing to the final pilot plant stage.

Kvanefjeld is projected to be one of the largest producers globally of key magnet metals including neodymium, praseodymium, dysprosium and terbium, along with by-production of uranium and zinc.

Technical optimisation of Kvanefjeld is part of an on-going program of co-operation with leading rare earth company and major shareholder Shenghe Resources Holding Co Ltd (SHA:600392).

This strategy sees the integration of world-leading Chinese rare earth processing technology with one the world’s most significant rare earth projects, with the aim of developing a simpler, lower cost rare earth value chain.

Shenghe had selected two leading laboratories in China to develop and enhance the flotation circuit.

Both laboratories have delivered excellent results, with improvements in mineral concentrate grade in the order of 60%.

The subsequent phase has involved transferring the development work to Australia, overseen by technical teams from China.

Based on results, the preferred of the two new methodologies will be selected for pilot plant operation.

Importantly, the significant increase in mineral concentrate grade with a reduced mass of solids will result in substantial reductions in the size of equipment leading to lower capital and operating costs of the processing plant circuit.

Efficient and cost-competitive concentrator circuit

Greenland Minerals managing director Dr John Mair said: “It is fantastic to have two established rare earth specialist groups assisting Shenghe in the optimisation program and final pilot plant specification.

“Each group has a pedigree in metallurgical work for production assets in China and delivered exceptional initial results for Kvanefjeld.

“The approach taken will ensure the establishment of the most efficient and cost-competitive concentrator circuit.”
