D301 resin is an anion exchange resin with tertiary amine group [-n (CH3)2] mainly on macroporous styrene-divinyl benzene copolymer.

D301 resin is an anion exchange resin with tertiary amine group [-n (CH3)2] mainly on macroporous styrene-divinyl benzene copolymer.

The resin has a specific pore structure, the skeleton has a specific strong, weak basic groups. It has a variety of excellent properties, especially for gold cyanide complex has a special selectivity, especially suitable for the recovery of a large number of gold containing poor liquid or waste liquid. Gold mine is mainly used for heap leaching and heap leaching cyanidation process, which can replace activated carbon for adsorption.

Characteristics of gold extraction resin:

1. The adsorption capacity of gold extraction resin is large, the saturated adsorption capacity of the resin is 40 g/l, and the gold content of the residual liquid adsorbed by the resin can reach a low level of 0.01 PPM at least.

2. The adsorption rate of gold lifting resin is fast, which is more than five times that of ordinary coconut shell carbon adsorption rate. The method of using resin adsorption column in series (generally level 2 can be used) for adsorption has a high adsorption rate and a high recovery rate.

3. Good selectivity and low interference to other metal ions (such as copper, nickel, iron, lead, etc.).

4. anti-pollution performance is good, you can use pure water or sodium chloride solution to clean it.

5. Wide range of application, mainly used for the adsorption of gold in cyanide solution, as well as the adsorption of gold dissolved in acidic solution or even aqua regia.

6. Wide adaptation conditions, he is not too harsh on the adsorption condition PH value, PH value 0 -- 14 can be.

7. There are various methods for the post-treatment of gold extraction, such as liquid analysis and reignition, or direct carbonization and burning at high temperature to directly refine into simple gold particles, with a high recovery rate.

8. Adsorption of ultra-low concentration gold poor liquid can be carried out, and the concentration below 1mg/L can also be treated, and the effluent quality can be achieved to 0.02mg/L. In this way, reasonable recovery and utilization of ultra-low content gold poor liquid and waste liquid can be conducted to reduce unnecessary waste and loss.
