Global demand for batteries is growing at about 15% each year driving demand for both Nickel and Cobalt. PBT are in a unique position to harness this growth and provide a cleaner, flexible and more affordable option for battery producers.

Our Innovation


Our patented Selective Acid Leaching (SAL) process. Discovered by the University of Queensland and commercially proven to produce high-quality, more affordable nickel and cobalt battery materials with a lower environmental footprint.

Main Business


We refine Mixed Hydroxide Precipitate (MHP) to produce nickel and cobalt materials for Lithium Ion Batteries (LIB). Our technology can also be used to recycle existing LIB materials creating a closed-loop lifecycle for these critical minerals

Global Processing


Our primary commercial refinery, K & E Germany, can produce the equivalent of 50,000 tonnes of NiSO4 (Nickel Sulphate) in varying nickel products. Our plant currently under development in Townsville, Australia will have the capacity to produce 125,000 tonnes of NiSO4 and 15,000 tonnes of cobalt concentrate from MHP feedstocks.

Removing Economic Barriers


PBT’s processing technology is supporting the global journey into the rapidly expanding renewables industry. PBT will also directly create new jobs in the Australian and International critical minerals industry, by providing both an economic primary production route and a competitive recycling production methodology.

We will also directly provide over 100 new jobs for North Queensland through our planned new refinery.

Environmental Benefits


Our metal processing is better for the environment which means the batteries made with our products are better for the environment. We don’t use the same high-heat or toxic solvents; diluents or modifiers as other processes and produce less waste and tailings. We create a strong clean separation of nickel and cobalt and can extract very high levels of the metals though our process.

Commercial Advantage


Our process can extract a specified quantity of nickel and produce flexible nickel and cobalt products. This could provide our customers with bespoke battery material on demand. Our advanced processing also solves recycling complications. We can recycle battery material faster without existing environmental impacts.
