Product:

DL301-II Resin-specific adsorption of gold

Product pictures:

Introduction:

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.
