Refining precious metals is a complex process, increasing the efficiency of extraction of precious metals through the use of ion-exchange resins significantly increases profit and profitability of production. The use of ion exchange resins for refining precious metals is widely used throughout the world. Due to the high cost of platinum group metals, gold and silver - increasing the purity of the product and increasing the percentage of extraction becomes the most important task of most refineries. Separation, purification and separation of precious metals - all this is done by sorption plants based on our ion-exchange resins.
