1. PAINPOINT DRIVEN OPENING

Are you scaling up your alluvial or eluvial gold operation and finding that your washing and recovery processes are the bottleneck? At a 500 TPH scale, inefficiencies translate directly into significant revenue loss. Common challenges include:
Inconsistent Feed Handling: Fluctuations in material size and clay content can choke traditional scrubbers, leading to unplanned downtime and reduced hourly throughput.
Inefficient Gold Recovery: Fine gold loss in the sluicing or screening stages due to poor scrubbing liberation or inadequate residence time represents permanent financial leakage.
High Operational Costs: Excessive water consumption, high wearpart replacement frequency on inadequately protected components, and the labor intensity of managing multiple disparate units erode profit margins.
Rigid Plant Design: Inflexible layouts that cannot adapt to variable ore body characteristics or future expansion plans limit the asset's longterm value.

The central question for plant managers and engineering contractors is this: how do you specify a 500 Tph gold mining washing plant that delivers guaranteed throughput while maximizing recovery and controlling total operational cost?

2. PRODUCT OVERVIEW

The 500 Tph Gold Mining Washing Plant is a modular, heavyduty processing system designed for the continuous washing, scrubbing, screening, and gravity concentration of alluvial/eluvial goldbearing material. Its core function is to liberate gold from gangue material (clay, gravel) and concentrate it into a manageable product for further upgrading.

Operational Workflow:
1. Primary Feed & Scrubbing: Runofmine material is fed into a robust trommel scrubber or rotary scrubber, where it is aggressively agitated to break down clays and dissolve cemented aggregates.
2. Sizing & Classification: The scrubbed output passes over vibrating screens to separate oversize waste rock. The undersize slurry reports to primary gravity concentration.
3. Primary Concentration: Highcapacity sluices or jigs capture liberated gold particles from the slurry stream, producing a primary concentrate.
4. Tailings Management & Water Handling: Waste tailings are conveyed to a designated area, while process water is typically sent to a settling pond for recirculation.

Application Scope & Limitations:
Scope: Ideal for largescale alluvial gold projects, riverine deposits, and weathered eluvial deposits where claybound gold is present. Suited for fixed plant installations or large semimobile setups.
Limitations: Not designed for hard rock (lode) ore processing requiring crushing and milling. Performance is highly dependent on consistent feed characteristics; excessive boulder content (>300mm) may require prescreening.
