Mobile Gold Washing Plant for Alluvial & Placer Gold Mining (100‑500 TPH)

Mobile gold washing plant is a wheel‑trailer‑mounted integrated gravity separation solution built for alluvial placer gold recovery. It targets dry river‑bed, beach and shallow overburden gold deposits, solving the pain point of frequent site relocation for small‑to‑medium scale gold mining operations.

Project Background

Many alluvial gold mining sites are scattered, without fixed workshops. Frequent mine‑site shifting makes stationary gold processing plants uneconomical. Operators need complete washing‑screening‑gold‑recovery equipment that can be towed and quickly put into production.

This mobile gold washing plant adopts wheeled mobile chassis, can be towed by excavator, wheel loader or truck. It integrates feeding, scrubbing, trommel screening and gravity gold recovery in one unit, with processing capacity ranging from 30‑500 TPH, suitable for 10‑hour continuous mining cycles.

Core Technical Challenge

1. Raw material contains clay agglomerates; clay must be fully scrubbed to liberate coarse gold, flake gold and fine gold particles.
2. Avoid sluice box blinding which causes fine‑gold loss. Realize dual‑channel recovery for coarse gold and fine gold.
3. Fast relocation and quick commissioning for remote mining areas without complicated foundation construction.
4. Flexible matching: adapt to different gold particle sizes from various placer deposits.

Process Flow

Loader feeding → Hopper with heavy grizzly → Scrubber → Rotary trommel screen 　

Raw ore is fed into the hopper by wheel loader. Heavy grizzly blocks extra‑large boulders. The scrubber breaks clay lumps, then material enters the rotary trommel for washing and sizing. Oversize rock waste is rejected. Under‑size slurry flows to downstream gravity separation equipment for capturing coarse, flake and fine gold.

Multiple gravity‑recovery modules are interchangeable according to ore conditions. It overcomes traditional fixed sluice‑box blinding issue, improves overall gold recovery rate.

Main Equipment Configuration

1. Feed hopper with heavy‑duty grizzly: block oversized rock
2. Scrubber drum: disintegrate sticky clay
3. Rotary trommel screen: wet washing and size classification
4. Wheeled trailer chassis: mechanical / hydraulic levelling support
5. Power system: diesel power pack for sites without grid electricity
6. Gravity recovery cluster: optional sluice box, jig, centrifugal concentrator

Key Features

• High mobility: Wheel‑mounted trailer chassis, towable by loader or excavator, no concrete foundation required.
• Integrated compact design: Feeding‑washing‑screening‑gold‑recovery all‑in‑one unit.
• Wide capacity range: 100‑500 TPH throughput for medium‑large placer mines.
• Flexible modular configuration: Switch sluice box, jig or centrifugal concentrator for coarse / fine gold ore.
• Diesel self‑powered: Work in remote mining locations without grid power supply.
• Easy maintenance: Simple structure, convenient spare‑part replacement for African and Central‑Asia mining sites.

Application Scenarios

• Dry‑land alluvial gold deposit, ancient river‑channel placer gold
• Beach sand gold, shallow overburden gold ore
• Small‑medium scale mobile gold mining projects in Africa, Central Asia and South‑East Asia
