Graphite iron

Method of recycling iron and aluminum from the waste ternary lithium ion battery, overall PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC process: leaching reaction: after the waste ternary lithium ion battery is broken, add sulfuric acid and hydrogen peroxide to it, and get the leaching liquid after the mixing reaction. Among them, the positive electrode active material of ternary lithium ion battery is lithium nickel cobalt manganese oxide or lithium nickel cobalt aluminate.


PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC

The leaching reaction method includes discharging, disassembling and crushing the waste ternary lithium ion battery, and mixing with water to make the slurry. Sulfur acid and hydrogen peroxide were added to the slurry for stirring reaction, so that most of the nickel, cobalt, manganese, lithium, copper and iron are converted into cations into the solution, get the immersion solution, and conduct PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal process.


what is magnetic separation in science?

The extraction solution is a ternary sulfate solution of nickel, cobalt and manganese, which contains impurities such as copper, iron and aluminum, and the pH value is about 0.5. Copper removal reaction: add iron powder to the resulting leaching solution, filter it after the stirring reaction, and perform the REDOX reaction to obtain the crude copper powder and copper removal solution. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC Can remove the iron from the lithium ion inside (FE2O3).
