1. ABERTURA ACIONADA POR PAINPOINT

Gerenciar uma operação de processamento de ouro requer equilíbrio no rendimento, taxas de recuperação, e custos operacionais. Equipamentos ineficientes ou não confiáveis ​​impactam diretamente seus resultados financeiros. Você está enfrentando esses desafios persistentes?

Taxas de recuperação abaixo do ideal: Inconsistent particle size liberation or poor separation mechanics can leave valuable gold in your tailings, representando uma perda direta de receita.
Alto tempo de inatividade operacional: Falhas mecânicas frequentes, excessive wear part changes, and unplanned maintenance halt your entire processing line, custando milhares por hora em perda de produção.
Excessive Energy and Water Consumption: Inefficient motors, bombas, and separation processes inflate your utility costs, eroding profit margins in an energyintensive industry.
Operação Intensiva em Mão de Obra & Riscos de segurança: Equipment requiring constant manual adjustment or posing spillage and dust hazards increases labor costs and exposes your team to unnecessary risk.

The right gold mining equipment must address these issues with engineering precision. How does your current setup measure up?

2. VISÃO GERAL DO PRODUTO: HighCapacity Gold Concentrating Centrifuge

This continuous centrifugal concentrator is engineered for highvolume gravity separation of free gold from alluvial deposits and hard rock milled ore. It is designed to replace or augment traditional methods like sluices and jigs in applications requiring higher throughput and finer gold recovery.

Fluxo de Trabalho Operacional:
1. Preparação de alimentação: Ore slurry is screened to the optimal feed size (normalmente 6 mm) and mixed with water to a controlled density.
2. Concentração Centrífuga: A pasta é introduzida em um tambor de rotação rápida. Centrifugal force pins material against the drum wall, where riffles trap highdensity gold particles while lowerdensity gangue is flushed out.
3. Descarga Contínua: Minerais pesados ​​concentrados, including gold, are automatically discharged at programmed intervals into a secure collection system without stopping the feed.
4. Gestão de Rejeitos: Depleted tailings exit the system for further processing or disposal.

Escopo de aplicação & Limitações:
Ideal para: Operações de placer de alto volume, primary gravity recovery circuits in hard rock plants, scavenging from flotation tails, and cleanup of amalgamation concentrates.
Limitações: Not suitable for dry feeds or clayrich ores without adequate scrubbing and classification. Efficiency declines significantly for ultrafine (100 malha) gold without preconcentration.

6. CENÁRIOS DE APLICAÇÃO

Alluvial Placer Operation – West Africa

Challenge A largescale placer mine was experiencing significant fine gold loss in its trommelbased system due to variable clay content and limited retention time.
Solution Implementation of two GC350 units in parallel downstream of scrubbing screens to act as primary concentrators.
Results Plant throughput stabilized at target capacity with a measured increase in overall recovery from ~65% to ~88%. The automated discharge allowed operation across three shifts with minimal new operator training.

Hard Rock Mill Scavenger Circuit – Canada

Challenge A quartz vein processing plant needed to recover liberated gravityrecoverable gold from cyclone underflow before it entered the flotation circuit, which had poor recovery for coarse gold.
Solution Installation of a single GC350 unit fed by a dedicated cyclone pack handling mill discharge.
Results The unit consistently produced a highgrade concentrate amounting to an additional 15% of total monthly gold production that was previously lost to flotation tails or locked in circuit recirculation.
