Waste ternary lithium batteries is recycled to produce nickel sulfate crystal, cobalt sulfate crystal, battery grade lithium carbonate and other products, as well as manganese carbonate, copper sponge, sodium sulfate crystal, aluminum alloy, aluminum alloy structural parts, copper foil, aluminum foil and other by-products.
Feed: Waste Ternary Lithium Battery
Main product: Battery grade lithium carbonate(Li2CO3≥99.5%),
Nickel sulfate crystal (Ni≥22%), Cobalt sulfate crystal (Co≥20%)
By-products: Manganese carbonate (Mn≥45.43%), Aluminum foil (ternary), Copper foil (ternary)
Aluminum alloy housing (ternary), Sponge copper (ternary)

After disassembly of waste ternary lithium battery, positive and negative powder (black mass), copper foil, aluminum foil are obtained. The copper foil and aluminum foil are packed in tons of bags and transferred to the by-product warehouse for storage and sale. The ternary black mass is sent to water leaching process. The pulp is pumped to filter press for filtration, and the filtrate obtained is sent to the mixed liquid tank for further iron and aluminum removal. The leaching residue is sent to the acid leaching process to recover nickel, cobalt and manganese.
The filtrate after Fe, Al, heavy metals and Ca removal process is then sent to MVR concentration and the lithium precipitation process afterwards, where industrial grade lithium carbonate product is produced. If battery grade lithium carbonate is required, further carbonization process is required.
The nickel-cobalt-manganese residue produced in the Lithium carbonate workshop is pulped and pumped for leaching and purification workshop for acid leaching - copper removal - iron and aluminum removal - settling press filtration - defluorination of purification solution to obtain nickel-cobalt-manganese sulfate purified liquid, which is adjusted PH value and sent to the extraction process for the next step of production.
The purified liquid goes through impurities extraction by extraction agent P204, cobalt extraction by agent P507 and nickel extraction by agent P507, and then the impurities reverse-extraction liquid (crude manganese sulfate), cobalt reverse-extraction liquid and nickel reverse-extraction liquid goes to ultrasonic and activated carbon two-stages oil removal process, and then be sent to evaporation crystallization workshop to produce nickel sulfate crystals and cobalt sulfate crystals. Manganese carbonate is produced by the process of impurity removal and manganese precipitation of impurities extrcation liquid, and sodium sulfate crystal is produced by the process of evaporation crystallization of sodium sulfate.
