Application of Di(2-ethylhexyl)phosphoric acid (D2EHPA)and 2-Ethylhexyl 2-Ethylhexyl Phosphate (P507) in Ternary Lithium Battery recycling


Normally ,Black mass mainly come from Ternary Lithium Battery or lithium iron phosphate Battery .

This item we mainly introduce Ternary Lithium Battery which include Metal ion of Nickle ,Cobalt ,

and Manganese  ;There are many way to get nickel sulfate, cobalt sulfate, manganese sulfate of

battery grade.

We just Introduce one of them

1. Use P204 extract leaching solution to get P204 raffinate and P204 loaded organic phase ;

and then use sulfuric acid reverse extraction  P204 loaded organic phase  to get manganese sulfate

2. Take 272 to extract P204 raffinate and get 272 raffinate and 272 loaded organic phase;

3. Use sulfuric acid reverse extraction 272 loaded organic phase to get Cobalt sulfate.

4. 272 raffinate is extracted by P507 and get P507 loaded organic phase that was reverse extraction

by sulfuric acid to get nickel sulfate
