1. PAINPOINT DRIVEN OPENING

Scaling your gold recovery operation to 500 Tph presents distinct and costly challenges. Are you experiencing:
High Operational Cost: Excessive water consumption and high reagent use in traditional gravity circuits eroding your profit margins per ton.
Inconsistent Recovery Rates: Variable feed grades and particle sizes leading to unpredictable gold loss, especially in fine and alluvial deposits.
Excessive Downtime: Frequent maintenance cycles on complex washing systems causing production halts and missed throughput targets.
Space and Infrastructure Strain: The footprint and water management requirements of conventional plants limiting deployment in remote or constrained sites.
Labor Intensity: Reliance on manual operation and monitoring for process control, increasing overhead and human error.

How do you achieve reliable, highvolume gold recovery while controlling operational expenditure and maximizing plant uptime? The solution requires a purposebuilt system engineered for scale, efficiency, and robustness.

2. PRODUCT OVERVIEW

A 500 Tph Gold Mining Washing Plant is a highcapacity, modular processing system designed for the primary concentration and washing of goldbearing alluvial, eluvial, or hard rock feed material. Its core function is to separate gold from gangue material through scrubbing, screening, and gravitybased concentration at an industrial scale.

Operational Workflow:
1. Feed Preparation & Scrubbing: Raw material is fed into a robust scrubber or trommel to break down claybound aggregates and liberate gold particles.
2. Primary Screening & Sizing: Material is screened; oversize (waste rock) is rejected, while undersize (goldbearing sands/gravels) reports to the concentration circuit.
3. HighCapacity Gravity Concentration: A multistage circuit, typically employing centrifugal concentrators and sluices, separates highspecificgravity gold from lighter sands.
4. Tailings Management & Water Recycling: Processed tailings are stacked efficiently, while process water is clarified and recirculated to minimize fresh water intake.

Application Scope & Limitations:
Scope: Ideal for largescale alluvial mining operations, placer deposits, and weathered conglomerate deposits where gold is liberated or can be liberated through scrubbing. Effective on a range of particle sizes from coarse nuggets to fine flour gold when configured appropriately.
Limitations: Not suitable for primary processing of hard rock ores requiring crushing and milling. Recovery efficiency is highly dependent on the degree of natural liberation of gold in the feed material.
