"YX500 Eco-Friendly Gold Leaching Reagent: A Revolutionary Product in Gold Metallurgy"
Product Description
In the field of gold metallurgy, an innovative product - the YX500 eco-friendly gold leaching reagent is quietly changing the industry landscape. Developed by Y&X Beijing Technology Co., Ltd., it has independent intellectual property rights and has successfully replaced sodium cyanide and is widely used in gold beneficiation and smelting production.
1. Outstanding Product Advantages
1.1 Excellent Environmental Performance
- YX500 is an environmentally friendly reagent with low toxicity, showing no or low toxicity to humans and other organisms. Its unique component structure ensures that even though a small amount of cyanide group (CN -) can be detected, it does not harm the environment.
- The developed "synergistic leaching" and "in-situ treatment" technologies enable the standard discharge of tailings slurry while ensuring gold leaching indicators. The overall technology has reached an international advanced level, and the "synergistic leaching - in-situ treatment" technology has reached an international leading level.
1.2 Superior Gold Leaching Effect
- The reagent has a high recovery rate and shows excellent performance in the gold leaching process of various gold-bearing materials. For example, in experiments in different ore dressing plants in various regions, satisfactory leaching rates have been achieved for ores with different grades and impurity contents.
- It has good stability and can maintain a stable gold leaching ability under different environmental conditions. It can work normally within a temperature range of 0 - 50°C and under various pH conditions (generally maintaining a pH value of 10 - 12).
1.3 Convenient and Efficient Use
- YX500 is a powdery solid, and its dissolution method is simple. It can be used after being fully dissolved in water at room temperature.
- The reagent preparation is convenient. The dosage can refer to that of sodium cyanide, and different concentrations of reagents can be prepared according to different ore grades and impurity contents. Generally, it is first prepared into a solution with a concentration of 15 - 20% and added at the same location where sodium cyanide was originally added.
- The product usage process is consistent with the conventional sodium cyanide leaching process and is applicable to various leaching processes such as heap leaching, pool leaching, carbon slurry, and stirring leaching. Moreover, the gold recovery method of the leaching precious liquid is the same as that of the cyanide leaching process, having no impact on the recovery rate.
1.4 Reasonable Economic Cost
- It has a low dosage and cost. Although in some cases, the reagent consumption for specific ores may be slightly higher than that of sodium cyanide, considering factors such as environmental protection treatment cost, hidden costs related to safety management, and the increased revenue due to the higher gold leaching rate, the overall cost has an advantage. For example, in an experiment in a carbon pulp processing plant in Hebei, although the reagent consumption per ton of YX500 is slightly higher than that of sodium cyanide, the cost of environmental protection treatment is significantly reduced, and the total cost of leaching + environmental treatment is more favorable for YX500.
2. Product Components and Principles
The main components of the YX500 gold leaching reagent include sodium carbonate tripolycyanate, alkaline thiourea, alkaline polymeric iron, and carbonate, etc. During the gold leaching process, the components work synergistically. The cyano-like groups (CN -) in the branched chain of carbonized sodium cyanurate are linked by covalent bonds. In an alkaline environment, they usually do not decompose into free cyano groups but have a similar complexation performance to free cyano groups. Together with other components, they can oxidize and complex gold.
3. Wide Range of Applications
3.1 Diverse Applicable Materials
- It is suitable for various gold-bearing materials such as gold and silver oxidized ores, primary ores, cyanide tailings, gold concentrates, roasting slag, and anode sludge.
3.2 Comprehensive Applicable Processes
- It is perfectly suitable for both traditional processes such as heap leaching and pool leaching and modern processes such as carbon slurry and stirring leaching.
4. Precautions for Product Use
4.1 Concentration and Environmental Monitoring
- Due to the fast gold leaching speed, it is recommended to regularly monitor the content of precious and lean liquid, pH value, and YX500 concentration. A too low pH value will increase the reagent consumption, while a too high pH value will affect the gold leaching effect; a too low YX500 concentration will affect the gold leaching rate.
4.2 Details of Reagent Dissolution
- After YX500 is dissolved, there will be a small amount of black slag (water-insoluble substances ≤ 3%, mainly iron-containing oxides). This is a normal phenomenon and has no impact on the leaching effect and subsequent operations. Instead, it further improves the product's safety performance.
4.3 Storage Condition Requirements
- It can be stored at a low temperature but should avoid contact with acidic substances and moisture. It is recommended to store it in a sealed manner. If the temperature is lower than 0°C during use, it will affect the gold leaching efficiency and leaching rate.
The YX500 eco-friendly gold leaching reagent, with its many advantages such as environmental protection, high efficiency, and economy, brings new hope and choice to the gold metallurgy industry. If you are looking for a high-quality gold leaching reagent to replace sodium cyanide, YX500 is undoubtedly your best choice. Please feel free to contact us for more information.
