Darwin Processing Facility

TNG Limited

TNG Limited (TNG) proposes to construct and operate the Darwin Processing Facility at Middle Arm, Darwin Harbour, within Lot 1817, Hundred of Ayers. The facility would process magnetite concentrate railed from TNG’s (separately proposed) Mt Peake Project, 1400km south of Darwin. The following products would be produced and exported through East Arm Wharf to international customers:

  • titanium dioxide – a pigment for use in paint, varnish, paper, plastics, and other materials including inks, fibres, cosmetics and food
  • vanadium pentoxide - for use as an alloying agent in steel, catalyst and ingredient in battery manufacture (including vanadium redox batteries)
  • iron oxide – the main source of iron for the steel making industry (also known as ferric oxide or hematite)


The project requires assessment under the NT Environmental Assessment Act 1982 and is a ‘controlled action’ under the Environment Protection and Biodiversity Conservation Act 1999. The project is being assessed at the level of an Environmental Impact Statement (EIS) under the bilateral agreement between the NT and Australian Governments. The relevant controlling provisions are: Listed threatened species and communities (sections 18 and 18A); and Listed migratory species (sections 20 and 20A).

The proposal was initially referred to the NT Environment Protection Authority on 27 October 2015 as the Darwin Refinery. The Terms of Reference for the EIS were issued on 20 May 2016.

The draft EIS is available for public comment. Comments are to be submitted on or before COB 21 February 2020
