1. ABERTURA ACIONADA POR PAINPOINT

Gerenciar uma operação de processamento de ouro apresenta desafios persistentes que impactam diretamente seus resultados financeiros. Are you contending with inconsistent recovery rates due to inefficient separation? Is excessive downtime for maintenance and liner replacement cutting into your production schedule? Are you facing rising operational costs from high energy consumption and water usage? Além disso, does the complexity of your current setup require highly specialized operators, creating staffing vulnerabilities? These issues translate to tangible losses: every percentage point of unrecovered gold and every hour of unplanned downtime represents significant forgone revenue. The central question for plant managers is how to achieve higher throughput and recovery while controlling operational expenses and simplifying maintenance.

2. VISÃO GERAL DO PRODUTO

This datasheet details our advanced line of Concentradores Centrífugos de Ouro, a critical component for the gravity separation stage in hard rock and alluvial gold recovery circuits. This equipment is engineered to maximize the capture of fine gold that traditional methods often miss.

Fluxo de Trabalho Operacional:
1. Introdução ao feed: Pasta, typically from a grinding circuit or screening plant, is continuously fed into the rotating concentrator bowl.
2. GForce Separation: High rotational speed generates centrifugal force, packing heavier gold particles against the collection grooves or riffles, while lighter gangue material is fluidized and washed away.
3. Concentrate Retention: Gold and other heavy minerals are trapped within the bowl's designed retention system.
4. Automatic/Manual Discharge: Depending on the model, concentrated material is either automatically discharged at set intervals or manually cleaned after a scheduled batch cycle.
5. Eliminação de Rejeitos: The waste tailings exit the machine for further processing or disposal.

Escopo de aplicação & Limitações:
Escopo: Ideal para recuperar ouro grátis >30 mícrons, as a primary concentrator in alluvial operations or as a secondary/tertiary concentrator in hard rock mills. Effective on both eluvial and placer deposits.
Limitações: Not suitable for chemicalbound (refratário) ouro ou ultrafino (<20 mícron) partículas sem pré-classificação. Feed particle size and slurry density must be controlled within specified parameters for optimal performance.

6. CENÁRIOS DE APLICAÇÃO

Hard Rock Mill – Gravity Circuit Optimization

| Desafio:| A sulfide ore mill was losing significant fine free gold to the flotation tailings due to an outdated gravity circuit with low recovery below 100 malha. |
| Solução:| Two centrifugal gold concentrators were installed as tertiary concentrators, processing the combined concentrate from shaking tables and spirals.| Resultados:| Dentro de um quarto, overall plant recovery increased by 2.8%. The concentrators paid for themselves in under nine months through additional recovered ounces, with markedly lower operating costs than the previous jig system they supplemented.

Alluvial/Placer Mining Operation

| Desafio:| A largescale placer operation needed higher throughput and more consistent performance than their legacy sluice systems offered, especially during fluctuations in feed grade.| Solução:| A battery of four centrifugal concentrators was deployed in parallel as primary roughing units after trommel scrubbing.| Resultados:| The operation achieved a consistent +95% recovery rate across variable feed conditions, with throughput increased by over 35%. The automated discharge reduced labor requirements per tonne processed by an estimated two manhours.
