Cationic flocculants are a type of chemical commonly used in water treatment, sewage treatment, paper manufacturing and other fields. Its main function is to interact with negatively charged suspended particles or colloids through the interaction of positively charged ions and negatively charged suspended particles or colloids, so that these particles or colloids can be aggregated into larger flocs, which are easy to separate from the water.
Specific uses include:
Water treatment and sewage treatment:
Cationic flocculants are widely used in drinking water, industrial wastewater and domestic sewage treatment. It can effectively remove pollutants such as suspended matter, silt, grease, bacteria and organic matter in water.
Papermaking industry:
In the papermaking process, cationic flocculants are used to improve the quality of pulp, promote fiber aggregation in pulp, and improve the strength and production efficiency of paper.
It can also help recover fine fibers in pulp and reduce pollutants in wastewater.
Petroleum extraction and drilling fluid treatment:
Cationic flocculants can be used for drilling fluid treatment in oil fields to improve the performance and recyclability of drilling fluid by aggregating and removing solid particles in drilling fluid.
Mineral processing:
During ore processing, cationic flocculants can be used to promote the aggregation of ore particles, enhance the efficiency of flotation and sedimentation processes, and help separate valuable minerals from ore pulp.
Soil improvement:
Cationic flocculants are also used in certain soil improvement processes, especially to help improve soil structure and increase water retention capacity.
Textile printing and dyeing industry:
During textile dyeing and processing, cationic flocculants can be used to remove suspended matter from dyes, prints and sewage to achieve purification and water reuse.

High-efficiency and eco-friendly new technology - gold leaching agent
Posted on Nov 18.2024
Gold leaching agent plays a vital role in the gold extraction process, and its main functions include the following aspects:
Dissolving gold: Gold leaching agent can effectively dissolve gold and separate it from the ore. For example, cyanide leaching extracts gold from the ore by reacting cyanide with gold to form a soluble gold cyanide complex.
Increasing leaching rate: Some leaching aids such as gold heap leaching aids can increase the permeability of the solution, prevent scaling of powder ore, and accelerate the dissolution and leaching of gold. This leaching aid is non-toxic, non-corrosive, and will not pollute the environment. At the same time, it can increase the leaching rate of gold and make full use of mineral resources.
Environmental protection: New environmentally friendly synthetic gold leaching agents are regarded as perfect substitutes for cyanide, with the characteristics of non-toxicity and non-polluting. These gold leaching agents will not cause harm to the environment during preparation and use, and meet the requirements of modern industry for environmental protection.
Reducing production costs: Some gold leaching agents reduce production costs by optimizing the extraction process. For example, by increasing the gold-carrying capacity of gold and shortening the production cycle, the consumption of production materials and production costs can be reduced.
Adapt to different ore types: Different gold leaching agents are suitable for different types of ores. For example, acidic gold-containing materials can use gold leaching agents containing copper bromate, tribromoacetyl chloride and other ingredients, which can form stable complexes with gold ions to improve extraction efficiency.
In short, the gold leaching agent can not only effectively dissolve gold and improve the leaching rate during the gold extraction process, but also reduce production costs. At the same time, it has environmental protection characteristics and is suitable for different types of ores.

The application of mercury in gold mining
Posted on Nov 14.2024
The methods of mining and refining gold have a rich history dating back to ancient times. Mercury, a unique chemical element, plays an important role in the gold mining process. Especially in the refining of gold ore and the separation of gold, mercury is widely used in a technique called the "amalgam process." The application of this method makes the gold mining process more efficient.
The chemical properties of mercury and the gold mining process:
Mercury has unique chemical properties, most notably its ability to form alloys with metals, especially gold to form amalgams. Mercury is liquid at room temperature, and it has a strong affinity for gold and can react quickly with gold to form gold amalgam.
The formation process of this alloy is as follows:
When gold in the ore comes into contact with mercury, the mercury quickly penetrates into the gold particles and reacts with them to form gold amalgam.
Through this method, gold can be separated from the ore. Gold amalgam has a lower melting point than pure gold, so it can be heated at lower temperatures to release the gold from the alloy.
Heating evaporates the mercury, and what remains is pure gold.
The advantage of this method is that it can efficiently extract gold from the ore, especially when the gold content in the ore is low, or the gold particles are small and difficult to extract through traditional physical methods (such as flotation, gravity separation).
