Process could make carbon capture cheaper by providing a use for trapped CO2

Carbon dioxide direct from a car’s exhaust has been captured and used to separate and purify metals. The technique could offer a much needed business incentive for capturing carbon dioxide to help mitigate climate change while offering a greener route for recycling economically important metals.
