E3 Lithium (TSXV:ETL), a high-growth lithium stock, has successfully produced 99.78 per cent pure battery-grade lithium hydroxide monohydrate (LHM), which is used in the production of cathode active material for lithium-ion batteries.
The LHM production process begins with refining the lithium concentrate produced through E3’s proprietary direct lithium extraction process, which yields lithium carbonate. The lithium carbonate is then converted into LHM, which is then crystalized into its final salt form. The battery industry generally requires LHM of a purity greater than 99.5 per cent.
E3 is currently working alongside major equipment vendors to scale up its refining process for commercial production, amid continual development to improve purity and lithium recovery.
“Ultimately, E3 Lithium aims to be a supplier directly into the battery industry,” Chris Doornbos, president and CEO of E3 Lithium, said in a statement. “Demonstrating that we can produce an industry-quality specification on conventional and standard industry equipment is an important and exciting step forward. The engineering work continues on this piece of the flow sheet to support the completion of our pre-feasibility study on the Clearwater Project.”
E3’s Clearwater project in Alberta features a preliminary economic assessment with a US$820 million net present value at 8 per cent after tax, a pre-tax value of US$1.1 billion, and an internal rate of return of 27 per cent after tax and 32 per cent pre-tax. The project’s resource stands at 16 million tonnes of lithium carbonate equivalent (LCE) measured and indicated and 0.9 million tonnes LCE inferred.
The battery-grade results follow positive production tests at the company’s direct lithium extraction field pilot plant in Alberta, with an initial lithium recovery of more than 94 per cent.
