1. ABERTURA ACIONADA POR PAINPOINT

Are you scaling up alluvial or hard rock gold operations but finding your recovery process a bottleneck? Gerenciando um 500 A taxa de alimentação TPH apresenta desafios distintos que impactam diretamente a lucratividade. Obstáculos operacionais comuns incluem:
High Volume Inefficiency: Conventional scrubbers and trommels struggle with consistent feed and claybound materials at this scale, leading to frequent blockages, consumo excessivo de água, and lost fines.
Downtime for Maintenance: Plants requiring daily liner changes, screen cleaning, or complex bearing assemblies lose hundreds of tons of potential processing per hour. Unplanned stoppages can cost tens of thousands per day in lost revenue.
Low Recovery on Fine Gold: Simple screening and sluicing systems often fail to capture micron gold particles, sacrificing significant value. Industry estimates suggest inefficient plants can lose 1025% of recoverable gold to tailings.
Elevadas despesas operacionais: Systems dependent on multiple conveyors, complex water management, and large crew sizes erode profit margins.

Is your current setup maximizing recovery while minimizing operational cost per ton? Can your washing plant handle variable feed material without constant operator intervention? The solution requires robust engineering designed specifically for highvolume, highrecovery operations.

2. VISÃO GERAL DO PRODUTO

O 500 TPH Gold Mining Washing Plant is a modular, heavyduty scrubbing, triagem, and gravity concentration system engineered for continuous, highcapacity operation. It is designed to liberate gold from alluvial deposits, materiais eluviais, and weathered ore.

Fluxo de Trabalho Operacional:
1. Esfrega primária & Desagregação: Feed material is introduced into a largediameter rotary scrubber, where robust lifters and highpressure water jets break down clay agglomerates and cemented gravels.
2. Triagem Primária & Dimensionamento: Discharged material is screened (typically at 10mm). Tamanho grande (+10milímetros) barren rock is conveyed to waste. Undersize (10milímetros) slurry containing gold reports to the secondary circuit.
3. Triagem Secundária & Concentração: The slurry passes over fine screening (por exemplo, 2milímetros) and/or a series of cascading sluices with optimized riffle design. Highdensity gold particles are trapped while lighter gangue material is washed away.
4. Gestão de Rejeitos & Esclarecimento de Água: Waste slurry can be directed to a settling pond or optional cyclone/water recycling module to reduce freshwater demand.

Escopo de aplicação & Limitações:
Escopo: Ideal para depósitos aluviais/placer, riverbank operations, and soft rock saprolite zones with high clay content. Effective on particle sizes from nuggets down to +100 mesh fine gold.
Limitações: Not suitable for primary crushing of hard rock quartz veins or processing lateritic nickel ores without significant precrushing. Performance is contingent on appropriate feed size distribution and controlled clay content.
