Looking for a Cost-Effective Way to Extract Gold from Ore? The Wet Pan Mill Might Be Your Answer

Wet Pan Mill: You Can Collect Gold at Low Cost

In the field of gold mining, cost control is key to profitability. For small and medium-sized mines, processing plants, or inpidual gold prospectors, finding an efficient, durable, and cost-effective grinding equipment is crucial. With 20 years of experience in manufacturing mining equipment, we will today provide an in-depth analysis of the wet grinding mill an equipment hailed as a low-cost gold extraction tool and how it can help you maximize your profits.

Overview of Wet Grinding Mills

A wet grinding mill, also commonly known as a wet mill or gold mill, is a traditional ore grinding equipment. It uses two heavy rollers that roll on a grinding plate, utilizing pressure and shear force to crush and grind the ore. Its core design principle is simple yet efficient, making it particularly suitable for processing ores containing free gold. It can grind the ore to the appropriate fineness, preparing it for subsequent gold extraction (such as amalgamation, cyanidation, or gravity separation).

Why is the Wet Grinding Mill the Ideal Choice for Low-Cost Gold Extraction?

Among numerous mining equipment options, the wet grinding mill has remained popular due to its outstanding performance in terms of low cost.

Core Advantages of Wet Grinding Mills

1. Extremely Low Investment and Operating Costs

• Low initial investment: Compared to large equipment such as ball mills, the wet grinding mill has a simpler structure and lower purchase cost, making it ideal for users with limited budgets.

• Low energy consumption: Its power configuration is usually smaller, and its power consumption is significantly lower than that of ball mills with the same processing capacity, significantly reducing long-term operating costs.

• Simple and low-cost maintenance: The mechanical structure is not complex, and wear parts (such as rollers and grinding plates) are easy to replace and cost-effective. Routine maintenance can be performed without the need for highly skilled technicians.

2. Efficient Gold Liberation and Recovery

• Selective grinding: The grinding method of the wet grinding mill has a certain kneading effect, which can more effectively liberate gold particles encapsulated in the gangue, while avoiding excessive pulverization of already liberated gold particles, thus improving the overall recovery rate.

• Compatible with amalgamation method: Mercury plates can be directly added during the grinding process, enabling grinding and gold extraction simultaneously, simplifying the process, and allowing for immediate recovery of some free gold, accelerating capital turnover.

3. Robust Durability and Strong Adaptability

• Robust structure: The main components are made of high-quality cast iron or alloy steel, ensuring durability and adaptability to harsh mining environments.

• Strong processing capacity:  It can not only process gold ore but also has excellent grinding effects on metal ores such as lead, zinc, iron, and molybdenum, offering a wide range of applications.

Successful Case Study

In a medium-sized gold mine project in Africa, the client faced challenges of unstable power supply and a tight investment budget. We recommended the 1200-type wet grinding mill, combined with a simple sluice box gravity separation process. After the equipment was put into operation, it performed excellently:

• Cost: Equipment investment was only one-third of the original ball mill plan, and power consumption was reduced by approximately 60%.

• Recovery rate: The ore was successfully ground to a fineness of 80% passing -200 mesh, allowing for sufficient gold liberation, and the final gold recovery rate remained stable at over 85%.

• Feedback: The client was very satisfied with the stable operation of the equipment and the speed of return on investment, and has placed additional orders.

Related Equipment Recommendations

To build an efficient micro-scale gold extraction production line, we recommend linking the wet grinding mill with the following equipment:

1. Jaw crusher: Used for primary crushing of ore, crushing large pieces of ore to a size suitable for feeding the wet grinding mill (usually -20mm), reducing the load on the mill.

2. Shaking table or centrifugal concentrator: As a gravity separation equipment after grinding, it efficiently recovers the liberated coarse and medium-grained free gold.

3. Amalgamation barrel or mercury plate: Used in conjunction with the mill to achieve immediate gold capture.

Frequently Asked Questions (FAQ)

Q1: Which is more suitable for me, a wet grinding mill or a ball mill?

A1: This depends on your scale and the nature of your ore. If you have a moderate processing volume (1-100 tons per day), prioritize low investment and low cost, and the gold particles in the ore are relatively coarse, a wet grinding mill is a more economical choice. If you have a large processing volume and require very fine grinding, a ball mill might be more suitable. We can provide professional solutions based on your specific situation.

Q2: What are the output and fineness of the wet grinding mill?

A2: The output and fineness depend on the model (common models include 1000, 1200, 1300, 1500, 1600, etc., where the number represents the grinding disc diameter) and the hardness of the ore. For example, a 1200 model processing medium-hard gold ore can achieve an hourly output of 1-2 tons, and the fineness of the output can usually reach 60%-85% passing -200 mesh. The fineness can be adjusted within a certain range by adjusting the scraper and controlling the water supply.

Q3: What is the lifespan of the wear parts? Is replacement difficult?

A3: The grinding wheels and grinding base are made of wear-resistant materials such as high-chromium alloy, ensuring a long service life. Under normal gold ore grinding conditions, they can operate continuously for several months. The replacement process is relatively simple; users can complete it themselves following the instructions or with our remote guidance, minimizing downtime.
