1. PAINPOINT DRIVEN OPENING

Are you facing escalating operational costs and unpredictable output in your largescale gold mining operation? For commercial buyers and plant managers overseeing hightonnage projects, the challenges of a 500 TPH washing plant are significant:
High Downtime from Blockages: Claybound or sticky material can halt your entire processing line, costing thousands per hour in lost production and labor for manual clearing.
Inconsistent Recovery Rates: Inefficient scrubbing and screening lead to goldbearing fines bypassing recovery circuits, directly eroding your project's profitability.
Excessive Water & Power Consumption: Outdated washing technology consumes unsustainable volumes of water and high horsepower, creating both environmental compliance pressures and crippling utility costs.
Rapid Component Wear: Abrasive feed material degrades liners, screens, and pump systems prematurely, resulting in frequent, unplanned maintenance shutdowns and high parts inventory costs.

Is your current setup delivering the consistent 500tonperhour throughput your reserve model requires? Are you achieving maximum gold liberation while controlling your most variable operating expenses?

2. PRODUCT OVERVIEW

The modern 500 TPH Gold Mining Washing Plant is a modular, heavyduty processing system designed for alluvial, elluvial, or weathered hard rock deposits. Its primary function is to disaggregate, scrub, and classify ore to prepare liberated gold for downstream concentration (e.g., sluices, centrifuges). China 500 Tph Gold Mining Washing Plant Factories

Operational Workflow:
1. Primary Feed & Scalping: Runofmine (ROM) material is uniformly fed via apron feeder to a robust scalping screen, removing oversized waste (+75mm) before the scrubber.
2. Intensive Scrubbing & Liberation: The core rotary scrubber or trommel uses internal lifters and highpressure water sprays to break down clay matrices and cementation, thoroughly liberating gold particles.
3. Precise Particle Classification: Discharged material is screened into multiple fractions (e.g., +10mm gravel waste, 10mm+2mm sand, 2mm slimes). This critical step ensures optimal feed sizing for downstream recovery units.
4. Tailings Management & Water Handling: Efficient slurry pumps and cyclones manage fine tailings streams. Integrated water recovery systems recirculate up to 90% of process water.

Application Scope & Limitations:
Scope: Ideal for surface mining operations with claybound auriferous gravels, saprolitic (weathered) deposits, and alluvial placer projects requiring highvolume throughput.
Limitations: Not suitable for competent hard rock without prior crushing. Performance is highly dependent on accurate feed characterization regarding clay content and plasticity.

6. APPLICATION SCENARIOS

West African Alluvial Gold Project | Challenge: Extremely sticky lateritic clays caused constant plugging in existing scrubber trommel, limiting throughput to <350 TPH with excessive manual cleaning. High seasonal rainfall complicated water management.| Solution: Installation of a purposebuilt 500 TPH washing plant featuring an aggressive doublelifter scrubber section for clay attrition and a primary dewatering screen for initial slimes removal.| Results: Achieved consistent design throughput of 480520 TPH within two weeks of commissioning. Plant availability increased from 92%. Water recycling rate reached >85%, mitigating seasonal supply issues.

Southeast Asian Weathered Hard Rock (Saprolite) Operation | Challenge: Inefficient classification led to significant gold losses in the 2mm+0.5mm fraction reporting incorrectly to tailings due to screen blinding.| Solution:: Deployment of a modular washing plant utilizing highfrequency Derrick®style screening technology for precise sand fraction separation ahead of gravity concentration.| Results:: Metallurgical accounting confirmed a recovery improvement of over 8 percentage points in the target size fraction. The modular design allowed installation on a constrained hillside pad without major earthworks.
