Phosphate rock producer Centrex Ltd., Adelaide, South Australia, on April 16 reported that its wholly-owned subsidiary, Agriflex Pty Ltd., has entered into a nonbinding Memorandum of Understanding (MOU) with Lithium Australia Ltd. The MOU represents a potential pathway to the battery market via the supply of phosphoric acid from Agriflex to Lithium Australia for the purposes of producing LFP or LMFP.
“We are excited to enter into this MOU with Lithium Australia, an Australian company that has developed significant know-how and expertise in the rapidly growing LFP battery market space,” said Robert Mencel, Centrex CEO and Managing Director. “As China currently dominates the global battery supply chain, concerns about supply security have led to increasing investment being driven towards more reliable jurisdictions, such as Australia.”
Mencel said the Australian Government’s recent decision to include phosphorous on its Strategic Minerals List also underscores the emerging opportunity for a domestic LFP battery operation. “With Australia’s significant lithium production base and the emerging global trend towards adopting LFP battery technology, the opportunity to establish an LFP battery operation in Australia is substantial,” he said.
The MOU, which has a 24-month term, envisions the construction of a demonstration plant for LFP or LMFP by Lithium Australia, potentially to be located in Queensland. The plant will have an estimated capacity of 250 mt/y of LFP or LMFP, which would require 200-300 mt/y of phosphoric acid.
If the demo plant is successful and the cathode powders are pre-qualified, Lithium Australia will seek to construct a commercial plant with an estimated capacity of approximately 25,000 mt/y LFP or LMFP, which would require 20,000-25,000 mt/y of phosphoric acid. Potential subsequent expansions to commercial plant capacity will be made in line with market requirements.
Both Agriflex and Lithium Australia will provide support to the MOU and will seek to progress towards a conditional binding offtake agreement for phosphate offtake. Lithium Australia will provide technical input and testing of phosphate samples from Agriflex in respect to their suitability for producing LFP and LMFP. Agriflex will conduct a study to produce phosphoric acid in Queensland and will provide Lithium Australia with phosphate product specifications.
