REAGENTS CALCULATIONS:
Knowing and adding the correct amount of reagent is critical in metallurgy.In plant operations, the throughput changes with time, consequently,
the reagent flow rate (L/min) should correspond to the desired dosage rate (grams of reagent per tonne of ore).
The same principle applies to laboratory batch tests where the volume of reagent solution (mL) added
should achieve the target dosage rate (g/t).

To use:
The dosage rate is calculated from the reagent flow rate (plant) or volume (laboratory).
The reagent flow rate (plant) or volume (laboratory) is calculated from the dosage rate.
