1. ABERTURA ACIONADA POR PAINPOINT

Are you scaling your gold recovery operations only to be constrained by washing and scrubbing capacity? Feed inconsistente, alto teor de argila, and inefficient fines recovery directly impact your bottom line. Considere estes desafios comuns:
Taxa de transferência com gargalos: Your existing scrubber or trommel can't keep up with excavator or dredge output, capping plant capacity at 300 TPH and leaving valuable material stockpiled.
Tempo de inatividade excessivo & Manutenção: Falhas frequentes em rolamentos, ofuscamento da tela, and unexpected breakdowns in harsh, abrasive environments lead to costly operational stoppages and high parts replacement costs.
Poor Clay & Fines Liberation: Inadequate scrubbing action leaves gold locked in claybound aggregates, resulting in significant recoverable gold reporting to tailings.
Água alta & Consumo de energia: Older designs are inefficient, consuming excessive water per ton processed and driving up operational expenses in remote sites.

How do you increase plant throughput to 500 TPH reliably while ensuring maximum clay breakdown and gold liberation? What solution minimizes unplanned maintenance and optimizes resource consumption for a superior return on investment?

2. VISÃO GERAL DO PRODUTO

The FDA Approved 500 A planta de lavagem de mineração de ouro TPH é um serviço pesado, modular scrubbing and classification system engineered for highvolume alluvial and eluvial deposits. It is designed to meet stringent requirements for materials handling in sensitive environments where regulatory compliance is critical.

Fluxo de Trabalho Operacional:
1. Alimentar & Pré-triagem: Runofmine material is fed via conveyor into a robust hopper with a grizzly section to remove oversize rocks (>75milímetros).
2. Esfrega Intensiva: Material enters the central rotating drum scrubber, where lifters cascade ore for maximum attrition, breaking down clays and dissolving agglomerates.
3. HighPressure Spray Washing: Internally mounted spray bars deliver highimpact water jets to disintegrate stubborn material coatings.
4. Triagem Eficiente & Classificação: Scrubbed material passes over modular screen panels (typically 10mm), with undersize reporting to downstream recovery (eclusas, centrífugas) and oversize conveyed to waste.

Escopo de aplicação: Ideal for largescale alluvial gold operations, placer mining projects, and heavy mineral sands beneficiation requiring highvolume feed processing.

Limitações: Not suitable for hard rock primary crushing or processing of highly cemented gravels without prior size reduction. Performance is dependent on consistent feed characteristics and adequate water supply.

Solução: Implementation of the GW500FDA as the primary scrubbing module ahead of existing gravity circuits.
Resultados: Atingiu um rendimento sustentado de 480 TPH of difficult claybound gravels. Clay liberation efficiency improved from 70% para 94%, leading directly to a measured 8% increase in overall gold recovery within the plant flow sheet within the first quarter.

Placer Mine Expansion Project, Yukon Territory

Desafio: A new project required an environmentally compliant solution capable of processing 500 TPH of frozen pay gravel within a strict permitting framework that governed materials contact surfaces.
Solução: Installation of the GW500FDA configured with steam injection manifolds at the feed hopper and FDAcompliant internal components.
Resultados: The plant met all regulatory requirements for permitting approval. The robust scrubbing action efficiently processed challenging frozen aggregates while the lowwater design reduced thermal input needs, keeping operational costs within budget projections.
