Under the leadership of Assoc. Dr. Fırat Burat from the Department of Mineral Processing Engineering, within the scope of the GAP project titled "Recovery Of Precious Metals From End-Of-Life Mobile Phone Lithium-Ion Batteries", the recovery of strategically valuable raw materials in the composition of mobile phone lithium-ion batteries is being investigated.
Lithium-ion batteries, primarily lithium and cobalt; There are plastics along with precious metals such as graphite, copper, aluminum, nickel, and manganese. With this project, the recovery of precious metals from end-of-life mobile phone lithium-ion batteries, which have high metal content, is achieved through ore preparation and enrichment processes, creating an environmental and economic process.
Selective removal of metals and plastic was achieved using physical and physico-chemical enrichment methods of copper, aluminum, iron, and plastic found in large fractions in end-of-life mobile phone batteries. In addition, after separating graphite from battery powder, which is concentrated in the finer size fraction and is more economically valuable, cobalt, lithium, nickel and manganese will be selectively recovered by hydrometallurgical methods.
Fractions obtained by crushing and classification processes.
Floating copper (a) and sinking aluminum, iron and nickel (b) particles as a result of froth flotation in size -2+03mm.
