| Abstract: |
| Pressure hydrometallurgy is one of the special metallurgical technologies, which is widely used in the separation, extraction, metal reduction and mineral synthesis of alumina, laterite nickel ore, sphalerite and gold ore. The development history of pressurized hydrometallurgy technology in China for more than 60 years shows that the production process, technical equipment and scale have reached the world advanced level. In the face of the increasingly fierce competition in the domestic and foreign non-ferrous metal market, energy conservation, emission reduction and environmental protection awareness, as well as the more stringent technical requirements of the production process, the pressure hydrometallurgy technology has increasingly shown its inherent technical advantages in the efficient and clean utilization of complex and low-grade refractory minerals, the pressurized hydrosynthesis and preparation, pressurized hydrohydrogen reduction and low-carbon metallurgy. In this paper, the development and characteristics of pressure hydrometallurgy technology are described, with emphasis on the research progress of clean production of alumina pressure hydrometallurgy, oxygen pressure leaching of sulfide ore and pressure hydrometallurgy of vanadium slag. Finally, the development prospect and direction of pressure hydrometallurgy technology in the future are prospected. |
