H1: 500 TPH Gold Mining Washing Plant: Engineered for HighVolume, HighRecovery Operations

PAINPOINT DRIVEN OPENING

Scaling alluvial or eluvial gold operations to 500 TPH introduces distinct operational and financial challenges. Inefficient material handling at this volume directly erodes profit margins. Are you experiencing:
High Losses in Fines Gold: Inadequate scrubbing and classification can lead to significant gold losses in fine particles, with industry estimates suggesting unrecoverable losses of 515% in poorly configured plants.
Unscheduled Downtime from Blockages: Heavy clay content can blind screens and clog sluices, halting your entire processing line for hours, costing thousands per hour in lost throughput.
Excessive Water and Power Consumption: Inefficient pump systems and oversized components not meeting their duty cycle can inflate operational expenses by 2030%, negating the benefits of high throughput.
Inconsistent Feed Grade Handling: A plant that cannot effectively handle fluctuations in feed material—from loose gravel to cemented conglomerates—creates bottlenecks and unstable recovery rates.

The central question for a plant manager is: How do you achieve reliable, efficient, and profitable gold recovery at a 500tonperhour scale without compromising on recovery percentage or operational stability?

PRODUCT OVERVIEW

The 500 TPH Gold Mining Washing Plant is a complete, modular processing system designed for the continuous recovery of placer and alluvial gold. It integrates robust scrubbing, precise classification, and efficient concentration into a single, coordinated flow.

Operational Workflow:
1. Primary Scrubbing & Disaggregation: Feed material is aggressively scrubbed in a largediameter trommel or scrubber to break down clays and cemented aggregates.
2. Size Classification: The discharged slurry is screened to separate oversize waste rock (+10mm to +75mm, depending on deposit). The undersize fraction reports to the concentration circuit.
3. Primary Concentration: A series of sluices or jigs capture the majority of liberated gold from the screened slurry.
4. Secondary Recovery & Tailings Management: Fine gold recovery units (e.g., centrifugal concentrators) may be employed for scavenging, with clarified water recirculated to minimize consumption.

Application Scope & Limitations:
Ideal For: Largescale alluvial/placer deposits, eluvial deposits with clay content, riverine operations requiring highvolume processing.
WellSuited For: Projects with consistent feed material over a defined particle size range (typically 100mm).
Limitations: Not designed for hard rock (lode) ore requiring crushing and chemical leaching. Performance is contingent on proper feed preparation (removal of oversized boulders) and consistent water supply.

APPLICATION SCENARIOS

West African Alluvial Gold Project

Challenge:A largescale concession with highly variable clay content was causing frequent screen blinding in their existing setup, limiting throughput to under 350 TPH with high gold losses in claybound fines.

Solution:A customconfigured washing plant was installed featuring an extended residence time scrubber moduleand a twostage screening deck.

Results:Achieved sustained throughput of480520 TPH, reduced screenrelated downtime by70%,and increased overall fine gold recovery by12%as measured against previous production audits.

South American Riverine Placer Operation

Challenge:The operation neededto relocate their processing plant every1218 months as mining fronts advanced,a process that previously took months using fixed infrastructure.

Solution:A fully modular washing plant built on skidmounted modules was supplied.

Results:The entire plant was disassembled,moved50 km upstream,and recommissioned within21 days,minimizing production interruption.Field data shows relocation costs were reduced by approximately40%comparedto previous methods.
