Gold Mining Wet Pan Mill
What is a Gold Ore Wet Grinding Mill?
A gold ore wet grinding mill is a key piece of equipment used in the fine grinding stage of the gold beneficiation process. In processes such as cyanide leaching for gold extraction, gold minerals need to reach extremely high fineness (usually requiring over 90% of particles to be -200 mesh or even finer) to ensure sufficient liberation and contact with the leaching agent, thus achieving a high gold recovery rate. The wet grinding mill is designed for this purpose. It uses the grinding action between a rotating grinding disc and a fixed grinding disc (or liner), with the participation of water, to further grind the slurry from the coarse grinding stage to the required fineness.
As a manufacturer with 20 years of experience in mining equipment manufacturing, we understand the decisive impact of the fine grinding stage on the final economic benefits. An efficient, stable, and energy-efficient wet grinding mill is the "efficiency bridge" connecting crushing and leaching.

Core Advantages of Wet Grinding Mills in Gold Ore Beneficiation
Compared with traditional ball mills, modern gold ore wet grinding mills demonstrate significant advantages in the field of fine grinding.
1. Higher Grinding Efficiency and Finer Product Particle Size
The grinding mill utilizes the principle of material layer crushing, concentrating energy on the mineral particles, resulting in higher grinding efficiency and easier achievement of uniform ultra-fine products. This is crucial for gold ore with complex inclusions and fine particle size distribution, effectively breaking down inclusions and exposing gold particles.
2. Lower Energy Consumption and Operating Costs
Due to its unique working principle, the energy consumption of a wet grinding mill is typically 20%-30% lower than that of traditional ball mills when achieving the same fineness requirements. Long-term operation can save customers significant electricity costs and significantly reduce the cost per ton of ore processed.
3. Simple System and Convenient Control
The equipment has a compact structure, occupies a small footprint, and is easy to integrate with existing processes. By adjusting parameters such as the grinding disc gap and feeding speed, the product fineness can be controlled quickly and accurately, offering high operational flexibility and convenient automation integration.
4. Good Environmental Performance and Safety
Wet operation eliminates dust pollution, resulting in a friendly working environment. At the same time, the enclosed system reduces the volatilization of reagents (such as cyanide), which is more in line with modern mining safety and environmental protection standards.

Case Study of Practical Application
Project Background: In 2022, we provided a complete wet grinding mill system for a medium-sized gold mine project in Ghana, West Africa. The ore in this mine has complex properties, with gold mainly existing in micro- and sub-microscopic forms within pyrite. The original process lacked sufficient fineness, resulting in a leaching rate that consistently hovered around 86%.
Solution: We replaced the original ball mill with a large energy-efficient wet grinding mill for secondary fine grinding. By optimizing the grinding disc material (using high-chromium alloy liners for corrosion and wear resistance) and adjusting process parameters, the final grinding fineness was stabilized at 95% passing -325 mesh.
Application Results: After the modification, the gold leaching rate increased to 93.5%, significantly improving gold recovery. At the same time, the system's unit energy consumption decreased by approximately 25%, the equipment ran smoothly, and maintenance requirements were low. The client recovered the equipment investment cost within 8 months through the increased gold recovery.
Equipment Selection and Related Recommendations
Choosing a suitable wet grinding mill requires considering the following key factors:
• Ore properties: Hardness, particle size distribution, and clay content.
• Processing capacity: Calculated in tons/hour (dry ore).
• Target fineness: The required final product particle size distribution.
• System integration: Whether it's a new project or an upgrade of an existing line.
We recommend conducting detailed ore test work before making a decision. Our technical team can provide experimental support and professional selection solutions. In addition to the main unit, we also recommend using the following supporting equipment:
1. High-efficiency hydrocyclone group: Forms a closed-circuit grinding system to improve efficiency.
2. Wear-resistant slurry pump: Ensures stable slurry transportation.
3. Automation control package: Enables online monitoring and automatic adjustment of feeding, concentration, and fineness.
Frequently Asked Questions (FAQ)
Q1: Are wet grinding mills and vertical mills the same equipment?
Not exactly the same. The principles of both machines are similar, but the wet grinding mill commonly referred to for gold mining is more focused on fine and ultra-fine grinding, and its structure may be specifically optimized for abrasive slurries. Vertical roller mills, on the other hand, are more commonly used in the building materials industry for grinding slag, cement, etc., and have certain differences in specifications and processing methods.
Q2: What is the lifespan of the wear parts of the equipment, and is replacement complicated?
The lifespan of key wear parts such as the grinding disc liners depends on the abrasiveness of the ore, typically lasting 6-18 months. Our equipment uses a modular design, making it very convenient to replace wear parts such as liners. This can usually be completed within 24-48 hours, minimizing downtime.
Q3: Is the wet grinding mill prone to clogging when processing sticky gold ore with high clay content?
This is a good question. Sticky ore does present challenges. Our solution involves optimizing the grinding disc structure and discharge method, adding a dispersion device to the feeding system, and recommending enhanced washing and desliming operations at the front end of the process. We can test your ore samples to ensure the reliability of the solution.
