Renascor Resources (ASX:RNU) has successfully produced graphite concentrate at its Siviour graphite deposit in South Australia, this week pulling the concentrate from a 730-tonne bulk ore sample run through conventional flotation.

Listen to the HotCopper podcast for in-depth discussions and insights on all the biggest headlines from throughout the week. On Spotify, Apple, and more.

Following a winter shutdown, the company re-staged its processing campaign and produced graphite concentrate at an average grade of 96.8% carbon. And, the flotation processing led to a graphite recovery of 96.5%, exceeding the parameters originally set for Siviour’s early-days campaign.

The graphite concentrate is now to be used as base feedstock for Renascor’s government-funded Purified Spherical Graphite (PSG) demonstration plant.

First-run deliveries of Renascor’s milestone concentrate are expected to arrive in South Australia “on schedule” as work on its PSG facility ramps up – that will become a fairly key focus next quarter, HotCopper understands.

This purification sets the producer up with one of the world’s cheapest sources of graphite concentrates, Renascor’s managing director, David Christensen, declared.

“Our work in maturing the technical readiness level of our purification process, including utilising the bulk sample material for our PSG development plant, offers an additional comparative advantage that can transform Renascor into a vertically integrated battery materials company,” he said.

“The competitiveness of our BAM project is underpinned by our Sivior deposit.”

It’s perfect timing, too, the company chief suggested, with the U.S. clamping down on Chinese anode material exports through anti-dumping duties and import tariffs – and Renascor is now ready to step in.

“[We can now] offer a secure and competitive source of high-value, 100% Australian-made graphite… to fill the growing ex-China demand for battery anode.”

Once it’s up and running, the Aussie smallcap hopes to use the demonstration facility to demonstrate commercial viability for its eco-friendly, hydrofluoric acid-free PSG process and then eventually become the first ex-China lithium-ion battery anode producer. South Korea’s POSCO has a stake in the facility.
