1. PAINPOINT DRIVEN OPENING

Are you scaling your gold mining operation and finding that your material washing and recovery processes are the bottleneck? Inconsistent feed, high fines loss, excessive water consumption, and unplanned downtime directly erode your profit margins. Consider these common challenges:
Throughput Inconsistency: Can your current plant reliably handle 500 Tph of variable claybound or alluvial ore without frequent clogging or bypassing?
Gold Loss in Fines: Are you seeing measurable precious metal values reporting to your tailings due to inefficient scrubbing and screening?
Excessive Operational Costs: How much are you spending on water procurement, recycling systems, and manual intervention to keep your washing stages operational?
High Maintenance Downtime: Is abrasive wear on scrubber liners and screen decks causing weekly shutdowns, delaying your production schedule?

A robust 500 Tph gold mining washing plant is not merely an addition; it is a critical system for liberating gold and ensuring downstream recovery efficiency. The right design addresses these pain points directly.

2. PRODUCT OVERVIEW

This product is a complete, modular 500 Tph Gold Mining Washing Plant, engineered for the primary scrubbing, clay breakdown, desliming, and size classification of goldbearing ores. It serves as the essential preparation stage ahead of gravity concentration or leaching circuits.

Operational Workflow:
1. Primary Feed & Scrubbing: Runofmine material is fed into a heavyduty scrubber, where highimpact paddles aggressively break apart clay conglomerates and cemented gravels to liberate gold particles.
2. Primary Screening & Waste Removal: Washed material discharges onto a vibrating screen. Oversize barren rock (+75mm) is typically conveyed to waste.
3. Secondary Washing & Classification: The undersize reports to a secondary washing trommel or screen deck for further rinsing and precise separation into key size fractions (e.g., +2mm for gravity feed, 2mm for advanced recovery).
4. Slurry Management & Water Recycling: Fine slurry from the process is channeled to a settling system or hydrocyclone bank, with clarified water recirculated to significantly reduce fresh water demand.

Application Scope & Limitations:
Ideal For: Alluvial/eluvial deposits, placer mining operations, and hard rock ores with significant clay content requiring attrition.
Limitations: Not a standalone recovery device; requires integration with downstream gold concentration systems (e.g., centrifugal concentrators, sluices). Primary crushing may be required ahead of the plant for very large feed material.
