Gold tailings refers to the waste produced after extracting gold from gold mines, usually containing gold, silver, copper and other metals, and the content is very low. In order to fully recover and reuse these metals, electrolysis of gold tailings is a common treatment method. This paper will introduce what equipment is needed for electrolysis of gold tailings and the precautions for use.
How to choose gold tailings electrolysis equipment
1. Electrolytic cell
Electrolytic cell is the main equipment of gold tailings electrolysis and the core of the whole electrolysis system. The selection of electrolytic cell should consider its size, material, current density and other factors. In general, the electrolytic cell should have good electrical conductivity, chemical stability and mechanical strength to ensure long-term stable operation. In addition, the size of the electrolytic cell should also be reasonably configured according to the production needs.
2. Power supply
Gold tailings electrolysis requires a lot of power support, so the choice of power supply equipment is crucial. In general, you can choose DC power or AC power. Dc power supplies usually use a rectifier to convert alternating current to direct current, while AC power supplies do not require this step of conversion. Different power supply types are different in terms of energy consumption, efficiency, cost, etc., and need to be selected according to the specific situation.
3. Cooling device
Electrolytic process will produce a lot of heat, if not timely heat dissipation, it will affect the effect of electrolysis. Therefore, the cooling equipment is also one of the essential equipment for the electrolysis of gold tailings. In general, you can choose water cooling, air cooling or coolant circulation and other ways to cool.
Precautions for use
1. Perform safe operations
Electrolysis of gold tailings is a high-risk operation, so safety must be ensured during operation. Operators should have a certain level of technology and safety awareness, strictly abide by the relevant operating procedures and safety norms, to ensure the safety and stability of the electrolysis process.
2. Maintain the device
The maintenance of gold tailings electrolysis equipment has an important impact on the life and performance of the equipment. In the process of use, the electrolytic cell, power supply equipment, cooling equipment and other equipment should be regularly maintained, and equipment faults should be found and solved in time.
Electrolytic equipment selection
Electrolysis is an important step in the treatment of gold tailings, so it is very important to choose efficient and reliable electrolysis equipment. In general, the gold tailings electrolytic equipment can be divided into three parts: electrolyzer, power supply and electrolyte.
1. Electrolytic cell
The role of the electrolyzer is to reduce gold ions to metals and deposit them on the cathode. In the selection of electrolytic cell, it is necessary to consider its design, manufacturing process, material, cathode area and other parameters. The common electrolytic cells are barrel electrolytic cells, horizontal electrolytic cells and vertical electrolytic cells.
2. Power Supply
Power supply is the core component of electrolytic equipment, its stability and quality will directly affect the efficiency of electrolysis and product quality. At present, there are two kinds of power supplies commonly used on the market, DC power and AC power, of which DC power is more common.
3. Electrolyte
The main function of the electrolyte is to provide gold ions and electrons. When selecting the electrolyte, it is necessary to consider its chemical properties, concentration, PH value, conductivity and other parameters. Common electrolytes are potassium cyanide electrolyte, sulfuric acid electrolyte and so on.
