Kimyasal metalurjide çevreci bir yaklaşım: Solvometalurji

Hydrometallurgy is an efficient and well-known method that is frequently used in metal extraction. However, due to the high amount of water used in these systems and the amount of waste acid released, alternative method research activities in the scientific world are increasing day by day. Furthermore, when the literature is examined, it is seen that the concepts of green chemistry and solvometallurgy come to the fore. In this study, green solvents used in solvometallurgical methods are defined and information about ionic liquids and deep eutectic solvents is given. Examples of solvometallurgical methods to primary raw materials are given, such as extraction of rare earth elements and copper from their ores. Also, detailed information is given about the recovery of metals from waste lithium-ion batteries, fluorescent lamp wastes, scrap NdFeB and SmCo magnets, and mine wastes by using solvometallurgical methods. In conclusion; the method is suggested as an efficient way to reduce the use of resources in production, especially the use of less water, and producing less amount of waste acid. It is expected to increase the number of publications related with solvometallurgy within following years. Also, studies about upscaling the method to industry is an ongoing process.
