CNLITE Eco-friendly Environmental Gold Dressing Agent Using Tips

CNLITE eco-friendly environmental gold dressing agent is a chemical agent that can replace sodium cyanide without changing the original nature of ore and in low toxicity and environmentally friendly. In the process of using CNLITE eco-friendly environmental gold dressing agent for gold extraction, what should be noted? The following article will briefly introduce the application method and precautions of CNLITE eco-friendly environmental gold dressing agent in gold processing plant.

CNLITE eco-friendly environmental gold dressing agent has two forms of powder and granules. The main components are sodium oxide, nitrogen, ammonium, calcium, iron and other materials. They are all packaged in two layers of plastic and net weight of each bag is 25.00KG±0.20KG, although the agents exist in different forms, the chemical properties and application methods are exactly same, so the required temperature, pH, dosage and dosage concentration are all same in the gold extraction.

1. Dosing concentration: In general, for 1-2g/t oxidized gold ore, the concentration of CNLITE eco-friendly environmental gold dressing agent should be 0.03-0.08%, but the dosage should be calculated according to the grade and impurity of gold ore. The commonly used formula is: dosing amount = (optimal concentration value - current measured concentration value) * dosing pool water volume.

2. Temperature: because CNLITE eco-friendly environmental gold dressing agent is soluble in water, it is extremely volatile with high temperature conditions, which will cause the waste of chemical. With low temperature conditions, the chemical reaction speed of gold extraction will be limited, and the effect of gold extraction is not obvious. Therefore, in actual production, keep the chemical reaction temperature to room temperature, and the experiment shows that when the temperature is higher than 10 degrees Celsius, the leaching effect of gold is obvious.

3. pH: due to the agent is alkaline, it will react with the gold extraction solution under acidic conditions, under neutral condition the reaction effect is poor. Therefore, CNLITE eco-friendly environmental gold dressing agent must be fully functional under alkaline conditions. In practical production, alkaline chemicals are generally used to provide a suitable chemical environment for gold extraction. The most commonly used are limestone and caustic soda and pH is maintained at 10-12. After the solution is poured into raw ore heap or leaching pool, the optimal pH is 11±0.5. As long as the pH is within this range, the effect of CNLITE eco-friendly environmental gold dressing agent is obvious.

4. Leaching: under the condition of normal temperature and alkalinity, CNLITE eco-friendly environmental gold dressing agent is dissolved in water for sufficient stirring and dissolution, and then the mixed solution is poured into the leaching pool. If heap leaching is adopted, the mixture solution can be added for feeding and spraying at the same time.

5. Washing and displacement precipitation: solid-liquid separation of gold-containing solution and solid tailings after leaching, usually includes replacement of gold-containing solution, concentration and filtration of leaching slurry, and overall cyanide extraction The process of gold is similar. The difference is that the precious and poor liquids of the CNLITE eco-friendly environmental gold dressing agent can be used multiple times.

In addition to the things to be aware of in the above gold withdrawal process, there are some tips on using CNLITE eco-friendly environmental gold dressing agent:

1. Due to the faster leaching speed of gold, the staff of the immersion factory should regularly check the concentration of precious liquid, poor liquid content, pH and CNLITE eco-friendly environmental gold dressing agent to ensure the leaching process is carried out normally and efficiently.

2. Since CNLITE eco-friendly environmental gold dressing agent is alkaline, it is easily oxidized by strong oxidants such as hydrogen peroxide and potassium permanganate. Experts do not recommend mixing strong oxidants with CNLITE eco-friendly environmental gold dressing agent to avoid the consumption of chemicals.

3. When leaching complex ore, the ammonia, sodium sulfide, potassium ferricyanide, lead nitrate and other drugs commonly used in the pretreatment stage do not react with CNLITE eco-friendly environmental gold dressing agent, and can be used directly.

4. CNLITE is a gold dressing agent with hygroscopicity, it should be avoided from dampness and stored in a cool, dry place with airtight seal.

The above information of CNLITE eco-friendly environmental gold dressing agent are just some common guides for you. In the actual production, some adjustment can be made according to the actual situation of ore properties, mineral processing technology to achieve the best mineral beneficiation effect. In CIL, CIP, heap leaching, pool leaching, all sliming zinc powder replacement process, there will be small differences in the use of CNLITE eco-friendly environmental gold dressing agent, but this does not affect the effect of beneficiation, which is also a wide range of applications of CNLITE gold dressing agent. When using gold dressing agent, the successful application of CNLITE eco-friendly environmental gold dressing agent can be used for reference.
