This brings us to lime, which is one of the most commonly used chemical reagents in mineral flotation due to its ability to economically and efficiently control pH. It is added at various points in the flotation circuit, whenever it is necessary to raise the pH, as calcium hydroxide (also known as hydrated or slaked lime, Ca(OH) 2) slurry.

Lime slaking. To investigate the effect of steamslaking and water slaking at different temperature on the microstructural and mineralogical characteristics of lime, 3 different batches of slaked lime were produced by slaking the same quicklime in different conditions (Table 2).Lime 'A' was produced at room temperature as a 'control' slaking process and, therefore, to be used as a ...

Temperature is the most reliable means of control when the desired outcome is consistent highly reactive lime slurry. Slaking temperature is directly related to reactivity. Detention Slakers and Vertical Ball Mill slakers measure temperature directly in the product zone and are therefore the easiest to control.
