  • Frontiers | Synthesis of 1-2-Hydroxyphenyl Dec-2-en-1

    The effect of pH on the flotation recovery of malachite is given in Figure 5A. It shows that the best flotation results for HPDO, BHA, SIBX, and DA are obtained at a pH of 8, 8, 8, and 6, respectively. The maximum recovery of malachite with HPDO, SIBX, and DA are close to 95%, but the maximum recovery of malachite with BHA is just 48.0%

  • PDF Investigation into the flotation of malachite

    The results showed that DEHPA exhibited an impressive selectivity for against calcite/quartz in the pH range of 6.0–9.0 and achieved superior recovery over


    For the flotation process, the two most common approaches are controlled CPS and the flotation method. The preferred method is dictated by the nature of the mineral makeup of the gangue
