and compared with the PSO LS-SVM model. Then the production data from a purification process of zinc hydrometallurgy was used to test the model precision. The test results show that the proposed model has...]. Hydrometallurgy, 2004, 73(1): 163-168.

concentration on the zinc solubility, which can provide thermodynamic references for the zinc hydrometallurgy. Key words: thermodynamics; predominance diagram; zinc hydrometallurgy; ammonia leaching 1... for hydrometallurgy. It thus established the foundation for ammoniacal leaching in copper and nickel hydrometallurgy. Many researches on the leaching of oxidized zinc ores have been carried out in ammoniacal......
2017 Abstract: Zinc leaching residue (ZLR), produced from traditional zinc hydrometallurgy process, is not only a hazardous waste but also a potential valuable solid. The combination of sulfate roasting...; sulfate roasting; water leaching; valuable metals recovery 1 Introduction In China, a large amount of zinc leaching residue (ZLR) is produced from the traditional zinc hydrometallurgy process. The huge......
