D301G

1) Product introduction:

D301G is a kind of macrospore polystyrene ion exchange resin. It is used exclusively in

gold extraction from alkali cyaniding mineral immersion liquid. Owing to the peculiar

skeleton structure of polymer, this resin has excellent physical and
mechanical properties and extremely high wear resistant property. It has also a high
gold exchange speed and high adsorptive capacity. It can separate gold and other
metal ion well. The elution and reproduce is easy. So it is really an ideal material
for gold extraction in wet-process metallurgy.

2) Physical chemistry properties:

 Particle size can be customized according to customer needs.

3) Note: 
D301G anion resin used in gold extraction must be done pretreatment.

4) About water treatment resin pretreatment program are as follows: 
D301G anion resin pretreatment
1, The resin is first loaded into the switch, the resin is sufficiently large backwash backwash

to clarify the water, and then wash Taisho, but also to wash the water clarification.
2, Regenerated with 5% HCL, the amount of regeneration liquid is 2.5 times more than the

volume of the resin must be regenerated flows, the reproduction end, soaks for 12-24 hours

and then rinsed with pure water to near neutrality.
3, Then 4% NaOH solution was regenerated with regeneration is 2.5 times the amount of the

liquid volume of the resin, 12-24 hours immersion , rinsed with pure water to meet the process

requirements in use.

5) About water with resin regeneration treatment program as follows: 
D301G anion resin pretreatment
1, the kettle (batch material) added 4% 4% NaOH solution regeneration, regeneration

liquid than 20 cm liquid layer.
Second, soak 2 hours, stirring every half hour during 5-10 minutes.
Third, after soaking, put the net regeneration solution.
Fourth, repeat the operation a total of three times.
Five, three times after the end of regeneration, can be put to use.
2, one gram of gold probably needs 800-1200mm weak base anion resin adsorption.
(According to the actual situation, such as liquid gold concentration, etc.)
3, Russia, cycle: 100- 150 cycles. Broken rate of 40% or resin adsorption capacity

decreased by 30% belongs to the scrap.
4, D301G resin or use after recovering 4% NaOH solution for use.
