"Ark Blue and Green+ : Innovative Lithium Solutions for a Sustainable World"

The lithium refining sector has four primary refining pathways which can be represented as Grey Refining, Yellow Refining, Blue Refining and Green+ Refining.

Lithium Ark is the inventor, developer and patent-holder of the Blue and Green+ Refining pathways.

In side-by-side comparisons, Green+ Refining provides the most superior set of ESG benefits and financial performance among all pathways. For some companies, Blue Lithium Refining is a compelling alternative since it generates zero waste in the manufacture of Lithium Hydroxide-BG, a vast improvement over conventional Grey Refining.

The Refining pathways are summarized and evaluated below

Lithium Ark Green+ Lithium Refinery

Our Green+ lithium refining process opens the door to lithium refining that requires zero reagents, has the lowest carbon emission and offers superior financial performance.

Lithium Ark Blue Lithium Refinery

Blue Lithium Refining is a process that is highly sought by companies in the nitrogen processing sector who wish to exploit existing capabilities in the manufacture of urea, ammonium, and other nitrogen-based products to also produce battery-grade lithium chemicals.

LiCl-Electrolysis Refinery (Yellow)

Lithium Chloride Electrolysis is referred to as Yellow Lithium Refining. It works converting Lithium Chloride (LiCl feedstock) into Lithium Hydroxide-BG by electrolysis.

Conventional Liming Refinary (Grey)
