BR301-II anion exchange resin for Gold adsorption CAS NO.55279-75-9

Application: The weak alkaline, acidic near neutral medium in the effective exchange of inorganic acid and silicate, and to a larger size impurities adsorbed molecules and the use of non-aqueous solution. Resin with high efficiency of the regeneration, Exchange capacity large, anti-pollution ability, mechanical strength, good benefits, this product is mainly used for hydrometallurgy, pulp instead of activated carbon from cyanide to extract gold. Desorption: Resin adsorption of gold thiourea with 9% + 3% sulfuric acid analysis, analytical dosage of 6-8 times the bed volume, contact time with Resin for 2h or more.

Regeneration process: Resin after resolution after washing, rinse with 2-3 times the bed volumeNaOH, about 1 hour, then rinse renewable HCl solution, the dosage is 2 times the bed volume, time is about 1.5h, washed clean and odor can be the last.
