Investigation of the Impact of Leaching Agent Concentration and pH on the Stability of Agglomeration of Ion-Absorbed Rare Earth Deposits

Figure 7

The concentration and pH of the leaching solutions influence the particle size distribution of ore samples. (a) Leaching solution concentrations range from 2.0% to 3.5%. (b) Leaching solution concentrations range from 3.5% to 5.0%. (c) Leaching solution pH range from 2 to 4. (d) Leaching solution pH range from 4 to 6.
