Researchers use standard gravity separation froth flotation technology to recycle AG3 battery materials
According to foreign media reports, chemical engineering students at Michigan Technological University in the United States have used century-old mineral processing methods to find an economical solution for recycling lithium-ion batteries.
The research team used two mining industry technologies to separate the components of the battery: the casing, metal foil materials, and the anode and cathode coatings.
The biggest advantage of this process is that it is cheap and energy-saving. In order to re-manufacture batteries, its recycled materials are of the same quality as the original materials, but at a cheaper price.
The team saw an opportunity to use existing technology to solve the challenges that are gradually emerging (battery material scarcity, insufficient supply, high prices, etc.). They used standard gravity separation technology to separate copper from aluminum, and then used froth flotation to restore key materials, including graphite, lithium and cobalt. This type of mining technology is currently the cheapest technology, and the required infrastructure is already in place.
To further promote the research, the Translational Research and Commercialization (MTRAC) Innovation Hub of Michigan Technological University provided financial support.
In addition, the project also received a grant of $15,000 from the U.S. Environmental Protection Agency.
