How to use gold absorbing resin in sewage

Hello, the general gold-absorbing resin has certain operating requirements for the precious liquor, as follows:

1. The noble liquid should be clear and free of suspended solids and colloids, 2. The gold should exist in ionic form, 3. The pH value of the noble liquid should be controlled between 5 and 11 as much as possible.

4. The following are the parameters of the use steps: DL301-II** special resin use process.

Pretreatment process:

Recommended use: 30g L (HCl) hydrochloric acid solution is washed into the exchange column for washing, the dosage is 2 times the bed volume, the time is about, and finally the pure water backwash method can be used from the washing pH value of 4-5. (Hydrochloric acid flow rate 2 mh, from wash flow rate 30-50 mh).

General use method: adjust the pH value to 1-2 with 30g L (HCl) hydrochloric acid solution, soak for more than 6 hours, stir every 1 hour, and the longer the conditional soaking time, the better, so that the resin can be fully transformed. Then wash with pure water from pH 4-5 and set aside.

Running process: 1) Resin filling method: Fill the pretreated resin into the ion exchange column, and the loading height should not be less than 1 meter. The resin loading volume is 65-75% of the volume of the ion exchange column.

Ion exchange column design is best if 3 or more ion exchange columns are connected in series) It is also possible to run on a self-designed device according to this principle.

2) Pay attention to the following points when running:

2-1) The precious liquid should be fed into the noble liquor from top to bottom, and the precious liquid should be a clear liquid, without turbid suspended solids and colloidal substances, the pH value should not be higher than 10, and the liquid level of the precious liquor should be kept 15-25 cm higher than the height of the resin.

2-2) The running flow rate is controlled at: 10-20 m h, the operating temperature range: 1 -40, and the best pH value.

Analysis process: After the resin is saturated with gold, it is dehydrated and dried, and the gold can be obtained after the direct high temperature of 1000 is completely ashed.

Since it is sewage, it must be filtered, and a filter is added before entering the resin. If there is oil, it has to be removed. ZOE-009 gold-absorbing resin is connected in series through the resin tank, and the gold-containing precious liquid can also be connected in parallel with less water every day. Looking at the pressure of the pump, it is recommended that the gold absorption rate in series is high and the water output is controllable.

A sucker! Won't the fire turn to ashes? You can suck about 300 grams.

Zhengzhou Qinshi company has a large amount of gold absorption resin, and can be incinerated or analyzed after use.

How to extract the ** in the resin.

Gold absorbing fiber can also be used.

It can be parsed, it can be incinerated. Gold absorption resin can adsorb more than 30 grams of gold per liter After the adsorption is full, the analytical solution can be configured for elution It is recommended to incinerate the secondary adsorption effect becomes worse after elution The incineration method is also simple and easy to operate If you don't understand, you can consult the manufacturer.

Resin gold absorption is the resin ion mesh exchange method, such as strong alkaline resin and macroporous bifunctional group resin, and the 353E type exchange resin currently used by Liang Xunfeng in large quantities. Suction process: slurry - adjust pH value - resin soaking - desorption - NaOH restoration.

It is directly used in the production of tail grinding line, and there are few cases at present. Because the rubber must improve the ion exchange cylinder or resin composite molding, it is also necessary to solve the technical problems of slurry acidity and alkalinity, flow rate, soaking time, exchange, desorption and recovery.

Seal with Tianna water, add wax for a period of time, and the resin will corrode the remaining ** genus.

Liquid analysis is carried out, the gold is washed off the resin with purified water and salt, and then the gold is precipitated and extracted.
