Develop a process for recycling of metals from electronic wastes using aqueous foams
-formulation of stable foams
-development of a process to make foams and recycle shredded metal wastes
-analysis of metal ions in solution
The recovery of valuable metals in WEEE (Waste from Electrical and Electronic Equipment) also called e-waste is becoming a major challenge to preserve natural resources while treating a large amount of waste. Hydrometallurgy processes, based on leaching solutions containing oxidants or acids to extract metals, were traditionally used for the mining industry for ore extraction, is also a promising route for the recovery of metals from WEEE. Hydrometallurgy is particularly suitable for local and short scale installations and presents a high efficiency and selectivity for the purification of metals. Its development is hampered by the large amounts of liquid effluents that need to be collected and treated. At SIMM laboratory we have developped leaching foams. They contain less than 10% of liquid and are thus a promising way of decreasing the environmental footprint of hydrometallurgy.
We are seeking for a chemical engineer who will extend our preliminary study and develop foams for the recovery of various metals as well as a conitnuous process enabling to produce the foams and efficiently have them in contact with shredded electronic wastes.
