1) Likewise, the preferential solubility of the precious metals in molten base-pared to their solubility in slag or matte is an inherent property of high-temperature systems that has few counterparts in hydrometallurgical processing.
2) Hydrometallurgical processes normally operate in the temperature range of 25~250℃
3) The advantages of hydrometallurgy are applicability to low-grade ores and to separation of high similar materials.
