Gold Washing Plant

Gold Washing Plant Core Features

High Recovery Efficiency
Our gold washing plant is customized according to ore specifications, ensuring the maximum gold recovery rate for your mining operations.

Intelligent Automated Processing
The plant is ingeniously engineered to automatically and simultaneously classify, concentrate and recover alluvial gold, minimizing the need for manual operator intervention throughout the process.

User-Friendly Operation & Maintenance
This gold washing plant is designed for ease of use. Operators only need 2–3 days of training to master its assembly, installation, operation and routine maintenance.

Eco-Friendly & Sustainable Design
The plant operates exclusively with recycled water and uses no toxic chemicals whatsoever. It enables efficient gold processing and recovery, guaranteeing clean, mercury-free and cyanide-free sustainable mining operations.

Heavy-Duty & Durable Construction
Manufactured with premium heavy-duty materials, the gold washing plant can withstand transportation challenges and continuous operation in harsh mining environments. What's more, it features extremely low maintenance requirements, reducing your long-term operaional costs.

Gold Washing Plant Process

The washing and dressing of gold mines are not accomplished overnight, it needs reasonable processes and steps.

01/

Screening
Alluvial gold mine often contains large gravel, which will affect the efficiency of alluvial gold washing and damage the equipment of the gold wash plant. Therefore, the first process of the gold washing plant is to screen the gravel in the gold ore. During the screening process, the soil on the gravel surface needs to be washed with water to ensure that the soil is flushed under the screen.

02/

Desliming
The effect of large gravel on gold washing plant has been removed after coarse screening. The second process is desliming, which is to fully dilute the gold and soil in the placer through water washing and mechanical scrubbing, so as to prevent the gold from being wrapped in the soil, so that the gold can be freed. Cylinder washing machine or spiral washing machine is often used to deal with placer gold with high mud content, and drum washing machine is often used to wash gold with low mud content.

03/

Gravity Separation
Gravity separation is the most common method to process alluvial gold, and the equipment used are chute, jig, shaking table, centrifuge, and so on. Among them, chutes and jigs are often used for roughing operations, and shaking tables and centrifuges are mainly used for concentration operations.

04/

Concentration
The main methods of alluvial gold concentration are gravity separation and amalgamation. Gravity separation method is to use shaking table or centrifuge to enrich and purify the coarse concentrate in jig and chute in the next step.

Packaging & Shipping

Testing Machine before package

Professional packaging: 1pc with poly bag. wooden case and canton box are available.make sure the machine is safe.

Shipping: By sea, By air.
• By sea: If customer not urgently the machine, we advice by sea, even though by sea took time is long, but by sea reduce much money about the freight, and it is good for customer if the machine is heavy and big size.

• By air: It is faster than by sea, but its freight is higher much than by sea, so this kind of type always suggest for light, small size and urgently demand machine.

FAQ

Q: What types of gold can a gold washing plant recover?

A: It is mainly used for alluvial/placer gold found in river sand, floodplains, and surface deposits. Recovery performance depends on gold particle size (coarse vs. fine gold) and ore characteristics.

Q: What capacity can a gold washing plant handle?

A: Capacity is typically measured in tons per hour (t/h) or m³/h. Actual throughput depends on feed size, clay content, water supply, and the selected separation equipment.

Q: What maintenance does a gold washing plant require?

A: Routine maintenance includes inspection of screens, trommel liners, pumps, hoses, bearings, and wear parts, plus scheduled cleaning of sluice mats and separators to maintain stable recovery performance.

Q: What payment methods do you accept?

A: We accept T/T, L/C, etc. A 30% deposit is required before production starts, and the balance should be paid before shipment.

Q: How is the quality of your products?(mining equipment/machine)

A: Our products are manufactured strictly according to national and international standard, and we will do a test on every machine before delivery.
