FIELD: hydrometallurgy.
SUBSTANCE: invention relates to hydrometallurgy and can be used to create waste-free technologies for the disposal of hazardous substances and environmental protection. The effect is achieved through the use of environmentally friendly reagents (water, ammonium bicarbonate, succinic acid), their repeated and repeated use due to simple low-cost regeneration, selective extraction of copper already at the preparatory stages.
EFFECT: reducing the cost of implementing a method for processing lithium-ion batteries, reducing the harmful environmental impact, increasing the degree of lithium extraction.
