Lynas Corporation's executive chairman Nicholas Curtis has declared the safe and efficient operation of the company's controversial Malaysia plant a reality.

Commenting on news the company had successfully commissioned the cracking and leaching rare earth extraction units at the plant, Mr Curtis said Lynas was now providing real-time data that assured people the plant was entirely safe for local communities and the environment.

"This is another significant milestone for Lynas," he said.

"We are excited to start creating value at the LAMP, and we look forward to sharing that value with all of our key stakeholders, including the communities in which we operate."

Lynas' Malaysian plant has raised the ire of many in surrounding communities who argue it poses a health and environmental safety risk.

Lynas has a temporary operating licence for the plant but the Save Malaysia, Stop Lynas group is still pursuing legal action to stop the plant from operating.

Despite the ongoing opposition, Lynas insists there is nothing to stop it from operating the plant and said commercial rare earth products would be available in the next few weeks with ramp up of production to take place over the next three months.
