Nontoxic gold extraction agent - "Jinhu" brand gold processing suitable for use in micro-fine gold oxide ores, gold brown iron ore, Arsenic gold, gold gold residue and sulfuric acid. The company has complete independent intellectual property rights; it has the advantages of environmental protection, strong gold-solving ability, good stability, fast recovery, low dosage, low cost, convenient storage and transportation, etc., and truly realizes the green “environmental gold-savingâ€! Gold agent is a multi-functional and high-efficiency new product, suitable for the recovery and utilization of micro-series gold-containing oxidized ore, semi-oxidized ore, pyrite , primary ore tailings, and superior in immersion gold production applications. Sodium cyanide has the advantages of environmental protection, non-toxicity, strong gold-soluble ability, stable performance, fast recovery, low cost, convenient storage and transportation, etc. It completely replaces the history of toxic and harmful humans of sodium cyanide and solves the problem of environmental pollution. It also solves people's worries, truly realizes “green environmental protection and safetyâ€, and through the country's most authoritative inspection department, Shanghai Entry-Exit Inspection and Testing Center and Beijing Airline Airlift Identification, the relevant project identification and testing of environmentally friendly non-toxic gold-plating agents. Non-toxic, harmless and safe to use. Cyanide especially difficult to process or can not handle gold ore (Cu, Fe, arsenic, antimony, sulfur, lead zinc sulfide carbon) can be directly recovered gold and silver.
(Stone sulfur + base catalytic mixture) immersion gold medicine has been applied for nearly one year, at least three tests can prove to be non-toxic and non-polluting. Comprehensive tests such as wastewater discharge and toxic environmental pollution comply with national industrial wastewater discharge standards. Actual use test: First: Since it was used in three mines in June last year, several dogs on the mine are normally drinking poor liquid and precious liquid, and there is no adverse reaction so far. Second: Farmers often go to drink our poor liquid and the water in the pool of precious liquids. There is no problem with any one cow (no dispute). Third: In the summer pool, we often find frogs and baboons swimming in the summer. The precious liquid and the poor liquid pool can make the frog survive. The dog in the mine has been drinking for nearly a year, and the cow often goes to drink. There have been no problems. So far, the dogs in the three mines are still alive. The cow is occasionally thirsty, and he runs to drink the water in the poor liquid pool. (There are people in the mountains who often bring cattle.) In the summer poor liquid and precious liquid pool, frogs and cockroaches will appear from time to time. At present, mines that are immersed in gold with sodium cyanide are not seen. These phenomena fully demonstrate the toxicity and environmental pollution of this drug, which can be ignored. Professional production to provide environmentally friendly non-toxic gold-plating agent non-toxic gold selection agent non-toxic immersion gold agent!
1. The application range of Jinhu brand non-toxic gold extracting agent;
1 Adapted ore types: gold, silver oxidized ore, primary ore, high sulfur and high arsenic gold ore, cyanide tailings, gold concentrate, sulfuric acid slag, anode mud, etc.;
2 Applicable beneficiation process: heap leaching, pool immersion, carbon slurry (stirring leaching), etc.
2, Jinhu product form: solid block or granular;
3, Jinhu dissolution method: can be used after fully dissolved in water at room temperature (generally in flowing water or after sufficient agitation will accelerate dissolution; when dumping, you can build a drug pool in the pool of lean liquid, so that after the carbon is returned Water directly washes the golden tiger into the poor liquid pool);
4, adjust the alkalinity: generally use lime or caustic soda to adjust and maintain the pH value of 10-12; when the pH value of the return water is reduced, the alkali should be adjusted in time; when the pH value is too high for a long time (more than 12), the alkali scale is likely to affect the activated carbon. Adsorption, or liquid passivation affects the leaching effect);
5. Calculate the dispensing:
1 Jinhu dosage can refer to the amount of sodium cyanide used. It is recommended to carry out the beneficiation test and refer to the best conditions; (commonly about 1-2g/t of gold oxide ore, the concentration of golden tiger is generally maintained at 0.3-0.8‰, Appropriate adjustment according to different ore grades and harmful components);
2 Calculation method of dosage: Jinhu tonic = (optimal concentration value - current concentration value) × water volume in the drug pool; suppose the optimal concentration value of Jinhu is 1.5 ‰ (by water quantity), return water concentration It is 0.6‰, 500 square meters of water in the poor liquid pool, then the amount of gold tiger tonic: (1.5-0.6) × 500 = 450 kg.
6, product use process: (consistent with the use of sodium cyanide heap leaching, carbon leaching process)
1 heap leaching, pool leaching process: raw ore crushing, pile / pool, leaching, activated carbon adsorption (zinc powder replacement), analytical electrowinning, smelting;
2 carbon slurry process (stirred leaching): raw ore crushing, grinding, carbon leaching, analytical electrowinning, smelting;
7. Other matters:
1 It is recommended to use special gold coconut shell adsorption carbon or zinc powder as auxiliary agent (the special activated carbon for carbon extraction in carbon slurry method);
2 The temperature is above 15 °C and the effect of using Golden Tiger is the best;
3 Because the immersion gold speed is faster, it is recommended to regularly check the grade of the liquid, the pH value and the concentration of the golden tiger;
â‘£ hydrogen peroxide, potassium permanganate, and the like with a strong oxidizing agent is not recommended Jinhu served together (pre-treatment can be used);
5 In the complex ore pretreatment, the use of ammonia, sodium sulfide, potassium ferricyanide, lead nitrate, sodium hypochlorite and other by-products does not exclude gold tiger immersion gold;
6 A small amount of black slag after dissolution of Jinhu does not affect the leaching effect;
7 Jinhu and sodium cyanide are not used at the same time;
8 carbon slurry method immersion gold, "oxygen leaching" link has an adverse impact on Jinhu.
Second, the Golden Tiger concentration detection method (titration method)
1. Required instruments: 1 50 ml conical flask, 2 10 ml pipettes, and 1 red head dropper;
2, reagent preparation: (use brown glass bottles to save, pay attention to avoid heat and light);
1 indicator: 1 whole bottle of A-like reagent is added to 500ml of acetone solution, stir completely dissolved and ready for use;
2 Test agent: Add 1 whole bottle of B-like reagent to 1000 ml of distilled water, stir completely dissolved and set aside.
3. Operation steps:
1 Take 10ml of the test solution in a 50ml Erlenmeyer flask, add 5 drops of indicator and shake it (yellow);
2 Pipette 10ml of detection reagent for titration; while shaking, shake while shaking, and observe the color change of the liquid, display pink to the end point, read the consumption of the consumed detection reagent (ie, the number of milliliters);
3 Conversion result: Golden Tiger concentration = ׉
3. Discharge treatment of waste residue and waste water: The ore waste residue and waste water after production are high in alkalinity. It can be added with a small amount of calcium chlorate (bleaching powder) and ferrous sulfate, and then discharged or stacked in a special tailings facility.
Fourth, product transportation and storage methods:
1. Jinhu is tested by the National Safety Production Shanghai Classification and Testing Center for Hazardous Chemicals and the Testing Center of Shanghai Chemical Industry Research Institute, and issued a national-level appraisal certificate to identify the products belonging to ordinary goods without explosion hazard. Safe transportation products that can be used for road, rail, sea and air transportation because of toxic oxidant risk, non-flammable dangerous goods, 6.1 non-toxic substances, non-radioactive dangerous goods, and non-corrosive products;
2. Strictly abide by the national transportation and storage system for chemical dangerous goods;
3, the product is hygroscopic, should be placed in a cool dry place sealed storage, pay attention to moisture, moisture; pay attention to direct oral inhalation of human and animal;
4. It is strictly forbidden to mix with acidic chemicals and food chemicals.
