The Cost of Inefficient Gold Ore Comminution: Are You Losing 1520% of Your Recovery Potential?
Every plant manager knows the bottleneck: if your primary crushing circuit fails to deliver a consistent, properly liberated feed, downstream grinding and leaching efficiency collapses. Industry data indicates that poorly matched crushing equipment can increase operating costs by $0.50 para $1.20 por tonelada due to excessive recirculation loads, premature liner wear, and downstream mill overgrinding. Are you facing excessive downtime from jaw crusher jams on highclay ores? Is your cone crusher producing too many fines, blinding your screens and increasing cyanide consumption? The solution lies in selecting equipment designed specifically for the abrasive, highcompressivestrength nature of goldbearing rock.
Visão geral do produto: The Gold Ore Primary & Secondary Crushing System
This datasheet covers a modular, heavyduty jaw and cone crushing circuit engineered for gold ore feed sizes up to 600mm, targeting a final product of 80% passing 1219mm for optimal SAG or ball mill feed. The workflow is designed for high availability in remote, highaltitude operations.
Fluxo de Trabalho Operacional:
1. Funil de alimentação & Pardo: Scalps 150mm fines to bypass the primary crusher, reduzindo o desgaste.
2. Esmagamento primário de mandíbula: Highstroke, deepchamber jaw reduces ore from 600mm to 150mm.
3. Surge Bin & Alimentador vibratório: Regulates feed rate to the secondary cone crusher.
4. Britagem de Cone Secundário: Hydrosetcontrolled, medium chamber cone reduces material to 1219mm.
5. Triagem de Circuito Fechado: Oversize material is recirculated to the cone crusher.
Escopo de aplicação: Ideal for hard rock gold (veios de quartzo, cinturões de pedras verdes) with compressive strengths up to 350 MPa. Limitações: Not recommended for highclay (>15%) saprolite ores without a dedicated scrubber circuit; throughput drops significantly with excessive moisture.

Cenários de aplicação
HighAltitude Underground Gold Mine (Andes Region)
Desafio: A mine at 4,200m needed to reduce haulage costs by precrushing ore underground. Space was limited, and ambient oxygen levels were low.
Solução: Installed a compact, VFDdriven GOC400 cone crusher on a lowprofile skid. The Hydroset system allowed remote CSS adjustment from the surface control room.
Resultados: Reduced skip hoisting cycle time by 18%. Eliminated manual liner adjustments in lowoxygen environment. Alcançou 98% disponibilidade acima 12 meses.
OpenPit Oxide/Gold Transition Ore (África Ocidental)
Desafio: The ore body contained variable clay content (512%) causing severe blinding of the primary jaw crusher and feeder.

Perguntas frequentes
1. Can this equipment handle highsilica gold ore (quartzo) sem desgaste excessivo?
Sim. The standard liners are 18% manganese with 2% cromo, specifically formulated for highsilica content. Os dados de campo mostram um 30% improvement in wear life over standard 14% Mn liners in quartzrich ore.
2. What is the minimum power requirement for the GOC400 cone crusher?
The crusher requires a minimum of 200 kW. No entanto, for optimal performance and to prevent motor stalling under full load, we recommend a 250 kW motor with a VFD. Operating below 200 kW will reduce throughput by approximately 15%.
3. How does the Hydroset system handle tramp iron?
The system monitors hydraulic pressure. If a noncrushable object (por exemplo, drill bit) entra na câmara, pressure spikes. The Hydroset valve opens instantly, dropping the main shaft to clear the object. The system resets automatically within 10 segundos.
4. What is the typical lead time for a standard package?
Current lead time is 1418 semanas a partir da confirmação do pedido. Isto inclui a fabricação, testes de fábrica, and crating for ocean freight. Premium packages may add 24 weeks for the remote monitoring system.
5. Can this circuit be integrated with an existing SAG mill?
Sim. The target product size (P80 of 1219mm) is standard feed for most SAG mills. We provide a data sheet for the conveyor discharge chute to match your existing mill feed bin. A surge bin with a capacity of 50100 tons is recommended.
6. What is the warranty on the main frame and shaft?
The main frame and eccentric shaft carry a 5year warranty against manufacturing defects. Peças de desgaste (forros, placas de bochecha) are excluded. The hydraulic system components carry a 2year warranty.
7. Do you provide operator training?
Sim. We offer a 3day onsite training program covering startup procedures, Ajuste CSS, liner changeout safety, and troubleshooting common issues like choke feeding and belt slippage. This is included in the Comprehensive Service Package.
