Sorption methods for the extraction, separation, purification and concentration of rare metals and other substances are based on the use of ion exchange processes between ion exchanger (solid ion exchange resin) and a solution containing the necessary components.
All equipment for ion-exchange sorptions manufactured at the enterprise is didided into:
- Working in a batch mode with a fixed layer of sorbent.
- Working in a continuous mode with complete circulation of the sorbent in the circuit.
For sorption in a fixed layer, sorption columns with a diameter of 100 mm to 1400 mm and a height of 800 mm to 5000 mm are used.
For sorption in continuous mode, columns operating in a dense sorbent layer are also manufactured; counter current ion exchange columns (PIC). These columns with a diameter of up to 1400 mm and a height of 5000 to 10,000 mm are used in the sorbent regeneration stage.
For sorption processes, we produce polypropylene tanks for an acid of ideal mixing with air mixing of Pachuk type with a geometric volume of up to 14 m³.
