1. PAINPOINT DRIVEN OPENING

Are you scaling your gold mining operation to meet production targets, only to be constrained by your washing and recovery plant? Operational bottlenecks at 500 Tph are not just an inconvenience; they represent significant, quantifiable losses. Common challenges include:

Inconsistent Throughput: Feed variability leads to surges and blockages, causing unplanned downtime and preventing your plant from consistently operating at its 500 Tph nameplate capacity.
High Water & Power Consumption: Traditional scrubbing and screening methods are often inefficient, leading to exorbitant water recycling costs and energy bills that erode profit margins.
Fine Gold Losses: Inadequate scrubbing of claybound materials or poor screening separation can result in precious metal reporting to tails, directly impacting your overall recovery rate and revenue.
Excessive Maintenance Downtime: Poorly designed chutes, underpowered motors, or abrasive wear on critical components lead to frequent stoppages for repairs, reducing overall equipment effectiveness (OEE).
Space & Logistics Constraints: A 500 Tph plant is a major installation. An inefficient layout can increase initial civil works costs and complicate material handling flows.

The central question is: how do you achieve reliable, efficient, and profitable highvolume gold recovery? The answer lies in a purposeengineered Certified 500 Tph Gold Mining Washing Plant Design Service.

2. PRODUCT OVERVIEW

This service provides a complete, engineered design package for a stationary or modular gold mining washing plant certified to handle 500 tonnes per hour of alluvial or eluvial feed material. The design encompasses the entire material workflow from raw feed to concentrated product.

Operational Workflow:
1. Primary Feed & Scalping: Oversized rocks and debris are removed via a heavyduty grizzly or scalper screen to protect downstream equipment.
2. Aggressive Scrubbing & Liberation: The heart of the plant, where robust trommel or scrubber barrels aggressively break down clay matrices and cemented gravels to fully liberate gold particles.
3. Efficient Screening & Classification: Properly sized vibrating screens separate the scrubbed material into multiple fractions (e.g., oversize waste, midsize gravels for additional crushing if needed, and fine sands/slimes).
4. HighCapacity Gravity Concentration: Designed slurry streams are routed through a series of highthroughput gravity concentrators (such as centrifugal concentrators or sluices) optimized for gold particle size distribution.
5. Tailings Management & Water Handling: An integrated water recycling system is designed to minimize fresh water intake, while tailings are managed for environmental compliance.

Application Scope: Ideal for largescale alluvial gold mining operations, mine expansion projects, or contractors requiring a definitive production asset. This service is designed for substantial, longlife deposits.

Limitations: This highcapacity design is not suited for smallscale artisanal mining or hard rock (lode) deposits requiring primary crushing and milling circuits.
