Chemical-enhanced filtration of Cu/Ni concentrate

  • Author / Creator

  • Filtration performance of mineral concentrate is mainly controlled by solid particle size and surface hydrophobicity. Filtration of coarser particles with more hydrophobic surfaces produces better filtration performance characterized by higher filtration rate (U) and lower final moisture content (FMC) in the final cake. Some filtration aids could improve filtration performance by flocculating solid particles and enhancing surface hydrophobicity. For the mineral concentrate used in this study, many filtration aids tested could only improve either U or FMC: one type was effective in improving U, and another type was effective in improving FMC. The combination of the two types of filtration aids at certain dosages could achieve better filtration performance than the optimum performance achieved by each individual filtration aid. Based on the experimental results, the working mechanism of filtration aids behind the filtration behavior was explored to deepen the understanding of the chemical-enhanced filtration of Cu/Ni concentrate.
