Precipitation test results showed that silicate removal reached 90% at an …
Interpretation of high base consumption in the flotation of gypsum
The pH of the slurry when above 8 decreases when the pulp is aerated as in flotation. To counter, a large amount of lime or other base (for example, sodium carbonate) is consumed. The origin of this effect is the solubility of gypsum. The solubility of gypsum releases Ca 2+ ions. As the pH is raised these ions coexist as CaOH + and Ca (OH) 2 ...
