The Hidden Costs of Inefficient Gold Recovery at Scale
Your 500 TPH operation faces three persistent challenges: declining feed grades forcing higher throughput demands, escalating water and energy costs consuming 3040% of operational budgets, and recovery losses of 1525% from claybound gold in weathered deposits. Each 1% recovery improvement at 500 TPH represents approximately $1.2M annually at current gold prices. When your washing plant delivers inconsistent liberation, downstream processing becomes a bottleneck—reducing CIL/CIP efficiency by up to 18%. Can your current system handle highclay ores without sacrificing throughput? Are you losing fine gold in slimes that bypass your recovery circuit? Does your washing stage actually prepare material for optimal gravity or cyanidation recovery?
Product Overview: 500 TPH Gold Washing Plant
This factorydirect, modular gold washing plant integrates scrubbing, screening, and primary recovery into a single continuous system designed for alluvial, elluvial, and weathered hardrock gold deposits. The plant processes 500 tons per hour of runofmine feed through a threestage workflow:
1. Feed Preparation – Variablespeed belt feeder with grizzly scalping removes +150mm oversize, directing 150mm material to the scrubber
2. Intensive Scrubbing – Dualdrive rotary scrubber with 18mm thick manganese steel liners breaks down clay agglomerates at 1215 RPM, achieving 95%+ liberation in 35 minute retention time
3. Screening & Classification – Multideck vibrating screen with polyurethane panels separates at 2mm and 6mm, directing 2mm slimes to thickener and 26mm concentrate to recovery circuit
4. Primary Recovery – Integrated jig concentrators or centrifugal concentrators recover free gold from the 26mm fraction, with tailings reporting to final waste stack
Application Scope: Alluvial gold mining, weathered oxide gold deposits, artisanal mining upgrades, and tailings reprocessing operations requiring high throughput with minimal water consumption.
Limitations: Not designed for primary hardrock crushing (requires 150mm feed), limited effectiveness on sulfidehosted gold without preoxidation, and requires minimum 400 m³/hour water supply at 4 bar pressure.

Frequently Asked Questions
Q: What feed moisture content can this 500 TPH plant handle?
The scrubber effectively processes feed with moisture content up to 18% (by weight). Above 18%, material handling on conveyors becomes problematic. For feeds exceeding 18% moisture, we recommend a dewatering grizzly or vibrating feeder with drainage slots. Field data shows optimal performance at 814% moisture, where clay liberation exceeds 96%.
Q: How does this plant compare to a trommelbased washing system?
Trommels typically achieve 7080% clay liberation versus 9598% for our rotary scrubber. The scrubber's counterrotational action and longer retention time (35 minutes vs 12 minutes for trommels) provide superior breakdown of plastic clays. Additionally, our polyurethane screens last 3x longer than trommel screen panels and allow for finer classification (down to 2mm versus typical 610mm for trommels).
Q: What is the expected gold recovery for different particle sizes?
Based on 18 months of field data across 12 installations: +500 micron free gold: 9799% recovery; 100500 micron: 9296%; 75100 micron: 8590%; 4575 micron: 6075% (varies with gold shape and liberation). For sub45 micron gold, we recommend adding a centrifugal concentrator module, which improves recovery in this fraction to 7085%.
Q: Can this plant be relocated after initial installation?
Yes. The plant is designed in 6 modular sections, each weighing under 35 tons. Standard configuration requires 57 days for disassembly and 710 days for reassembly at a new site. The mobile trackmounted option reduces relocation to 4 hours for movement within the same site. All electrical and piping connections use quickconnect fittings.
Q: What is the typical power consumption at 500 TPH?
Average power draw is 1.4 kWh/ton (range: 1.21.6 kWh/ton depending on feed characteristics). This compares favorably to industry average of 2.0 kWh/ton for equivalent throughput. With VFD control, power consumption drops to 1.2 kWh/ton at 400 TPH and increases to 1.6 kWh/ton at 550 TPH.
Q: What warranty and aftersales support do you provide?
Standard warranty covers 12 months from commissioning or 18 months from shipment, whichever occurs first. Coverage includes structural defects, gearbox failures, and motor defects. Wear parts (liners, screen panels, jig hoses) are excluded. Extended warranties up to 36 months are available. Our service team responds to critical failures within 48 hours in most mining regions.
Q: How does the factory wholesale price compare to dealerdistributed plants?
Our direct factory pricing eliminates 1525% dealer margins. A comparable 500 TPH plant from a dealerdistributed manufacturer typically costs $850,000$1,200,000. Our factory price of $680,000$1,080,000 includes the same or superior specifications. Volume discounts apply for orders of 3+ units (5% for 35 units, 10% for 6+ units).
