Oct 17, 2017 The term "ion exchange resin" or "ion exchange polymer" is an insoluble matrix or support structure normally in the form of small 0.25 2 mm diameter beads fabricated from an organic polymer substrate, such as crosslinked polystyrene or polystyrene divinyl

Gold recovery with ion exchange used resins

2001 6 1   The cationic resin could not recover gold from the solution and was then eliminated as a candidate for the job. The measured concentration histories in the solutions in contact with the anionic resins are shown in Fig. 4, while in Fig. 5 the amounts recovered by the resins, calculated with Eq. 5, are shown.These figures clearly show that, when NaOH is used as regenerant,

Ion Exchange Resin to Recover Gold from Acid Solution

2021 2 4   A few drops of concentrated nitric acid were added to the 195Au tracer solution and to the solutions of common metals to prevent reduction of gold by trace impurities in the chloride salts from which these metal solutions were prepared. The test solutions were diluted to 250 ml before they were passed through the ion exchange column.
