BATON ROUGE, La. (AP) — Avalon Rare Metals, which announced plans to build a $300 million rare earth elements separation plant and refinery in Geismar two years ago, has decided against building the Ascension Parish facility.

Company officials say Avalon’s plans to build the rare earths refinery in Geismar were abandoned after the company struck a deal with chemical company Solvay, utilizing its separation plant in La Rochelle, France.
