Hydrochloric acid (HCl) leaching of black mass obtained in the battery recycle process has the advantage of higher recovery of metals. 

Applying the Ark process, no additional waste materials such as sodium sulfate (Na2SO4) will be generated and the process is 100% circular by recovering the potassium chloride and generate the potassium hydroxide and hydrochloric acid, reducing the environmental impact and the energy consumption significantly. 

Let´s make battery recycling really circular!

Below a diagram of battery recycle is shown and how lithium ark process can be implemented.
