| Abstract: |
| Compared with traditional hydrometallurgy process, pressure leaching technology is a strengthening hydrometallurgical process with the advantages of fast reaction speed, high metal leaching rate and environmental friendly. Since industrialization in 1887, it has been widely used in uranium, copper, aluminum, zinc, nickel, cobalt, molybdenum, gold and other industries. In this paper, application and research status of pressure leaching technology in rare and precious metals industry were summarized, including primary minerals such as molybdenum, gold and PGMs, as well as secondary resources such as copper anode slime, scattered metal enrichment and arsenic-containing solid wastes. On the basis of summarization, the future development trend of pressure leaching technology in rare and precious metal industry is prospected. |
