Chemetics wins contract for sulfuric acid plant for the Nolans' NeodymiumPraseodymium project

Arafura Rare Earths has entered into an agreement for the supply of the sulfuric acid plant for its 100% owned Nolans NeodymiumPraseodymium (NdPr) Project in the Northern Territory. The sulfuric acid plant will be supplied by Chemetics Inc. a global supplier of sulfuric acid and other specialty chemical facilities, a wholly owned subsidiary of Worley. The sulfuric acid plant for Nolans will utilize Chemetics proprietary CORE-SO2 process which significantly reduces capital cost, maintenance cost and sulfur dioxide emissions from the plant.

The Chemetics plant is also significantly smaller than a traditional sulfur burning acid plant allowing increased use of modularization reducing the volume of site installation labor. These savings were incorporated into the recent Nolans project update. The initial work package includes finalization of specifications and engineering design to allow the plant to be incorporated into the overall project design.

Arafura’s General Manager Projects, Stewart Watkins, said, “Letting the contract for the supply of the acid plant to a global supplier such as Chemetics provides confidence around the outcomes for the Project when the team reaches commissioning. Along with that, the progress made on the selection of our key vendors and placement of long lead orders means that we are set to commence early works construction in the coming weeks.”

As well as the sulfuric acid plant, the Company has also placed several other the orders during recent weeks which are on the critical path for the project, including:

  • Sulfation bakes and cooler paddle dryers with ANDRITZ, primarily to secure detailed design and long lead materials for fabrication.
  • Pipe supply for the first 8 km of HDPE piping for the main water supply pipeline from the borefield to the plant site, which is required for early construction works.
  • Potable and wastewater treatment plants for the construction camp.
  • Equipment and tankage for temporary construction water supply in advance of the pipeline being installed to site.
