The solubility of quartz minerals was slightly affected by the solution pH, suggesting that the process variable pH has little effect on the equilibrium rate. However, precipitation caused quartz to dissolve at a rate of 0.04 mmol.L −1.s −1 at 45 °C but increased to 0.07 mmol.L −1.s −1 at 65 °C in 0.8 s.
