Abstract
In 2018, The silver(referred to as Ag) demand in the electrical and electronic field was 249 million tons, and for producing solar modules, 81 million tons of silver were demanded. Currently, due to the rapid increase in solar module installation, the silver demand is also increasing drastically in Korea. However, Korea's metal resources and reserves are insufficient compared to consumption, and the domestic self-sufficiency rate of silver ores among metal resources is lower than 1.5%. It implies that the recycling technology for recovering valuable metal resources contained in the waste plating solution generated in the metal industry is necessary. Therefore, in this study, through B/C analysis, the economic evaluations were compared and analyzed according to the improvement of the valuable metal recovery process in the waste plating solution. As a result, the B/C ratio was 1.48, which means feasibility. Therefore, the improvement of recycling technology has a high possibility to reduce the usage of chemicals and energy, and to improve resource productivity in the urban mining industry.
