Challenge in reagent dosing.
In the dosage of reagents for mining there is the main challenge of the unknown chemical formulation of reagents, coupled with an evolution to stronger collectors which require a smaller amount of flow to dose. The UD-Line® Reagent Dosing System integrates the measurement of the dosed flow and its design is based on the correct selection of materials according to the chemical compatibility of the reagent used, resulting in a high precision and low maintenance system.
Unknown chemical formulation, important characteristics:
a) Corrosives (Collectors that attack SS316)
b) Solvents (Collectors that attack plastics)
c) Flammable (Diesel and collectors)
d) High risk to health (NaSH, CuSO4, etc.)
The dosing system design follows this classification of the reagents. This makes it difficult to define the materials of the dosing system components in contact with the reagent, especially seals and gaskets.
The evolution to stronger collectors, which imply doses lower than 20 ml / min even in large mining. Micro flow dosing system design (<100 ml / min).
