Lithium treatment of waste

Disused lithium battery, and contains a large number of non-renewable mineral resources of high economic value, such as cobalt, lithium, nickel, copper, aluminum, etc., if they can effectively deal with abandoned or substandard recycling lithium batteries, can not only reduce waste batteries on the file environmental pressures, and also avoid causing cobalt, nickel and other metal waste of resources.

First, lithium pretreatment of waste, including discharges, dismantling, crushing, sorting;

After dismantling recycling plastic and iron shell;

After sorting electrode material for alkaline leaching, acid leaching, cleaning after the extraction. Extraction is a key step, the copper and cobalt, nickel separation; copper into the groove for EW EW EW copper products produced;

After extraction of cobalt and nickel extraction solution then, when after crystallization was concentrated directly cobalt salt and nickel salt; or separated by extraction of cobalt and nickel respectively, into the electrodeposition bath, get drilled and electrowinning of nickel electrowinning products.

Drilling electrodeposition step, copper, nickel recovery rate of 99%, and grade 99.98% respectively, 99.95% and 99.2% to 99.9% cobalt sulfate, nickel sulfate, and so meet product standards.
