Metal Recovery from Waste
Critical metals are intrinsically rare in the earth’s crust, poorly concentrated by natural processes and virtually un-available in UK but nevertheless are, by themselves or as compounds, key to advanced technologies in many applications. Molten salts provide the key to recovering these metals in a low cost, robust and waste feedstock agnostic method. The main research activities include study of chloride and borate molten salts, study of molten salt interfaces and electrolysis.
