1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Are you scaling up your alluvial or hard rock gold operation and finding that your washing and recovery processes are the bottleneck? At a planned 500 Tph throughput, common pain points quickly escalate into significant financial losses:
Manejo inconsistente del alimento: Variable clay content or particle size distribution can blind screens and clog scrubbers, leading to frequent stoppages and reducing effective capacity well below 500 Tph.
Inefficient Fines Recovery: Traditional sluices or jigs often struggle with gold fines below 150 micrones, resulting in unrecovered value reporting to tailings. Incluso un 0.1% loss at this scale represents substantial annual revenue erosion.
High Water & Consumo de energía: Inefficient plant design leads to excessive water recirculation and oversized pump requirements, inflating both operational costs and environmental footprint.
Excessive Maintenance Downtime: Poorly constructed or configured washing modules suffer from abrasive wear, requiring frequent liner changes and component replacement, cutting into productive operating hours.

Is your current setup reliably achieving target availability and recovery rates at a true 500 Tph? Are your operating costs per ton under control, or are they being undermined by inefficiency?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

A 500 Tph Gold Mining Washing Plant is a modular, highcapacity processing system designed for the primary scrubbing, classification, and gravity concentration of goldbearing ores. Se transforma crudo, excavated material into concentrated heavy mineral product for further upgrading.

Flujo de trabajo operativo:
1. Fregado primario & Disaggregation: Feed material is aggressively scrubbed in a robust trommel or rotary scrubber to break down clays and cemented aggregates.
2. Particle Size Classification: The discharged material is screened to separate oversize waste rock (+10mm to +75mm, depending on ore) from valuable undersize.
3. Primary Gravity Concentration: The undersize slurry reports to primary concentrators (p.ej., concentradores centrífugos) to recover free gold and heavy minerals.
4. Gestión de relaves & Water Clarification: Processed tailings are dewatered via cyclones or linear screens, with clarified water recirculated to minimize fresh water demand.

Ámbito de aplicación & Limitaciones:
Alcance: Ideal for alluvial/eluvial deposits, placer operations, and freemilling hard rock ores where liberation occurs via scrubbing. Effective on a range of materials from weathered conglomerates to lateritic clays.
Limitaciones: Not suitable for refractory ores requiring chemical leaching or complex sulphide ores needing flotation. Performance is highly dependent on accurate feed characterization (clay content, humedad, particle size).
