| Abstract: |
| Pressure leaching technology, a hydrometallurgical process with high efficiency, has been widely used in heavy metal industry of Cu, Zn, Ni and Co, and also in rare and precious metal industry of U, Mo, Au and PGMs. Application and research status of pressure leaching technology in heavy metal industry of Cu, Pb, Zn, Ni, Co and their by-products were summarized, including primary minerals such as Cu, Zn, Ni and Co sulfides, nickel laterite, as well as by products in metallurgical processes such as copper anode mud, arsenic residue, copper mud, waste dusts, smelting slag bearing copper and cobalt, zinc leaching residue, enrichment containing Ga and Ge, lead matte, copper residue, cobalt matte etc. On the basis of summarization, future development trend of pressure leaching technology in heavy metal industry is prospected. |
