ProdApplicable ore types: gold and silver ores, cyanide tailings, gold concentrates, roasted sulfates, lead-zinc roasted residues, anode mud, etc., various materials containing gold and silver. Applicable beneficiation processes: heap leaching, pond leaching, carbon slurry process (stirred leaching), etc.uct Detail
Method of dissolving Jinzhibao: It can be used after fully dissolving in water at room temperature (generally, dissolving will be faster in running water or after thorough stirring; when heap leaching, a dosing pool can be built beside the barren solution pond, allowing the return water after carbon treatment to directly wash Jinzhibao into the barren solution pond).
Adjusting alkalinity: Lime or caustic soda is generally used to adjust and maintain a pH value between 11±0.5; when the pH value of the return water decreases, alkalinity should be adjusted promptly; when the pH value is too high for a long time (greater than 12), it can easily produce alkaline scale affecting activated carbon adsorption, or cause liquid passivation affecting the leaching effect.
Dosage Calculation:
1. The dosage of Jinzhibao can fully refer to the usage amount of sodium cyanide, and it is recommended to conduct beneficiation tests and refer to its optimal conditions; (For commonly 1-2 g/t gold oxide ore, the concentration of Jinzhibao is generally maintained at 0.3-0.8%, adjusted according to different ore grades and harmful components);
2. Method for calculating the dosage: Jinzhibao supplement dosage = (optimal concentration value - current measured concentration) x water volume in dosing tank; assuming the optimal concentration of Jinzhibao is 1.5% (by water volume), the return water gold concentration is 0.6%, and the poor solution tank contains 500 m³ of water, then the Jinzhibao supplement dosage: (1.5 - 0.6) x 500 = 450 kg.
Product Usage Process: (same as using sodium cyanide for heap leaching or carbon-in-leach process)
1. Heap leaching and tank leaching process: ore crushing, pile/tank charging, leaching, activated carbon adsorption (zinc powder displacement), elution and electro-winning, smelting;
2. Carbon pulp process (stirred leaching): ore crushing, grinding, carbon leaching, elution and electro-winning, smelting.
Other Matters:
1. GoldTreasure works best when the slurry temperature is at room temperature, but it should not be lower than 10°C;
2. Due to the fast gold leaching rate, it is recommended to regularly check the gold content in rich and poor solutions, the pH of the solution or slurry, and the concentration of GoldTreasure;
3. Strong oxidizers such as hydrogen peroxide and potassium permanganate are not recommended to be mixed with GoldTreasure (they can be used for pretreatment) to prevent consumption of some GoldTreasure reagent;
4. The use of chemical reagents such as ammonia, sodium sulfide, potassium ferrocyanide, and lead nitrate in the pretreatment of complex ores has little impact on the gold leaching effect of GoldTreasure;
5. A small amount of black insoluble matter after dissolving GoldTreasure does not affect the effectiveness of the reagent;
Mixing GoldTreasure with sodium cyanide has no adverse effect on the leaching of gold and silver;
In the carbon slurry gold leaching process, the "oxygen-rich leaching" process may adversely affect the leaching effect of GoldTreasure.
Concentration Testing Method (Titration Method)
Required Instruments: 1 50ml Erlenmeyer flask, 2 10ml pipettes, 1 dropper with red head.
Reagent Preparation: (Store in a brown glass bottle, avoid heat and light)
1. Indicator: Add the entire bottle of reagent A into 500ml of acetone solution, stir until fully dissolved, and set aside;
2. Test Solution: Add the entire bottle of reagent B into 1000ml of distilled water, stir until fully dissolved, and set aside.
Operating steps:
1. Take 10 ml of the test solution and place it in a 50 ml conical flask. Add 5 drops of indicator and shake well (turning yellow);
2. Use a pipette to draw 10 ml of the test reagent for titration; during titration, add drop by drop while shaking and observe the color change of the liquid. When it turns pink, it reaches the endpoint. Record the amount of test reagent consumed (in milliliters);
3. Calculating the result: Jinzhibao concentration = (milliliters of test reagent consumed / 2) * 100%Operating steps:
1. Take 10 ml of the test solution and place it in a 50 ml conical flask. Add 5 drops of indicator and shake well (turning yellow);
2. Use a pipette to draw 10 ml of the test reagent for titration; during titration, add drop by drop while shaking and observe the color change of the liquid. When it turns pink, it reaches the endpoint. Record the amount of test reagent consumed (in milliliters);
3. Calculating the result: Jinzhibao concentration = (milliliters of test reagent consumed / 2) * 100%Operating steps:
1. Take 10 ml of the test solution and place it in a 50 ml conical flask. Add 5 drops of indicator and shake well (turning yellow);
2. Use a pipette to draw 10 ml of the test reagent for titration; during titration, add drop by drop while shaking and observe the color change of the liquid. When it turns pink, it reaches the endpoint. Record the amount of test reagent consumed (in milliliters);
