How to Use Eco-Friendly Reagent to Extract Gold?

Why Choose CNLITE? 

CNLITE (eco-friendly gold leaching agent) is an ideal substitute for sodium cyanide, specially designed for the extraction of precious metals such as gold and silver. Compared with the traditional cyanidation method, CNLITE has the following breakthrough advantages:

Key Advantages:

1. Eco-Friendly:

CNLITE is environmentally friendly, its ingredients are sodium oxide, there is no emission of highly toxic substances during the production process, the leaching residue is classified as general industrial solid waste, and the treatment cost is reduced by more than 80%.

2. Wide Range of Application: 

(I) Objects: Materials containing gold and silver, such as gold and silver ores, gold and silver tailings reuse, gold concentrate, sulfuric acid slag, lead-zinc slag, anode slime, etc.

(II) Processes: Heap leaching, pool leaching, Dump leaching, carbon-in-pulp, carbon-in-leach etc.

3. Stable Performance: 

It can reduce the influence of harmful substances such as arsenic and sulfur, and make the gold extraction process stable.

4. Faster Leaching: 

When heap leaching, the reaction rate is faster than using sodium cyanide.

5. High Leaching Rate: 

It can extract gold effectively and have higher leaching rate than sodium cyanide.

6. Lower Cost: 

Because of its special nature, it can reduce the cost of purchasing, shipping, warehousing, usage and environmentally friendly equipment.

7. Easy to Use: 

Because it can be completely substituted for sodium cyanide in the cyanidation process, it is convenient to use and can replace at any time.

8. Easy to Transport: 

Due to its stable nature, it can be transported by rail, sea, road and air. There are no transportation restrictions like sodium cyanide.

How to Use CNLITE?

1. The production operation method is the same as the sodium cyanide process, and the expensive liquid and the poor liquid in the production can be reused.

2. Agent Consumption

(I) It is recommended to conduct a leaching test first to determine the consumption and concentration of the agent at the optimal leaching rate. More agent may be used according to test results during production, and the optimal amount should be determined based on actual effects.

(II) If CNLITE is used as a substitute for sodium cyanide, the original dosing system may be referenced for the amount of CNLITE.

(III) Example: the common oxidized ore and drug dose are 1000g~2000g/ton, which is about 1.0 ~ 2.0‰ of the ore quantity.

Different properties of ore, different grade, different ph, willaffect the amount of the potion. The actual dosage can be calculated accordingto the mass concentration of the liquid.

3. Gold extraction, activated carbon adsorption, zinc powder, zinc wire replacement, The best leaching effect of gold was achieved when the ambient temperature was above 10℃.

4. CNLITE potion is compatible with cyanide extract. The leaching rate of CNLITE potion is 18-28% faster than that of cyanidation. (CNLITE is slower in the early stage and faster in the late stage than that of sodium cyanide) It is advisable to use more drugs according to the experimental data (to avoid the impact on gold leaching and unnecessary waste of drugs).

5. Toxicological information

•   Identification of Corrosive Hazard：The product is not classified in corrosives.

•   Hazardous wastes-Identification for toxic substance content：The content of CN- in the test sample does not exceed the linit.

•   Animalstimulus data: mild irritation

•   The determination of six valence Chromium solid waste: Arsenic, Cadmium, Chromium, Copper, Nickel, Lead, Zinc, all of them do not exceed standard.

6. Heap leaching dosing method

Calculate the amount of water in the tank, weigh and dispense the potion according to the amount of water.

CNLITE is to be weighed in a ratio of one kilogram percubic meter of water.

Put it in a strainer and let CNLITE potion hang in adispenser, and the pipe will run straight or stir to dissolve the potion.

At room temperature after the powder agent with water fullydissolved can be used. (dissolution is usually accelerated in running water or aftersufficient stirring) (a dosing pool can be built beside the lean liquid pool whenpouring)

(allow the backwater after the charcoal to flush the reagentdirectly into the poor liquid pool).

Adjust the alkalinity of about 11.2 before first adding the potion.When the water in the pool is low, pour alkali and the potion together. Can usetwo to rush dush bucket to rush dush lime respectively (or caustic soda) with medicaments to dissolve into medicaments cistern (pool of poor liquid) or putmedicaments cistern to dissolve, assure potion concentration in cistern is even.

Heap spraying process, dosing, spraying can be carried out atthe same time.

Initial stage: control the mass concentration of the potion isabout 1‰ (that is, the ratio of potion to water is 1:1000, that is, 1 kg of potionplus 1 cubic water), for 7-10 days.

Middle stage: the quality concentration ofthe control liquid is about 0.5‰, and the time is 20-30 days.

Later stage: the mass concentration of the control potion isabout 0.3‰, the time to the end of adsorption.

The PH value of backwater is kept stable at about 11.2.
