1. ABERTURA ACIONADA POR PAINPOINT

Are you managing escalating costs and unpredictable downtime in your gravity separation circuit? Taxas de alimentação inconsistentes, inefficient water management, and high maintenance cycles on your concentration tables directly impact your bottom line. These operational challenges manifest as lost fine gold, increased reagent consumption, and laborintensive cleanup procedures. Como você consegue resultados consistentes, highgrade concentrates without sacrificing throughput or requiring constant operator intervention? The solution lies in optimizing a core component of your recovery plant: the shaking table.

2. VISÃO GERAL DO PRODUTO

Our Wilfleystyle mineral concentrating shaking table is engineered for the efficient separation of heavy mineral particles, specifically for gold recovery in both alluvial and hard rock processing plants. It operates on the principle of differential particle density and size across a riffled deck subjected to a reciprocating motion.

Fluxo de Trabalho Operacional:
1. Introdução à pasta: A controlled slurry feed (tipicamente 2030% sólidos) is introduced at the head of the table.
2. Estratificação & Separação: The reciprocating motion and wash water flow stratify particles; denser minerals (por exemplo, ouro) settle into the riffles, while lighter gangue material is carried across and off the table.
3. Coleta Concentrada: Highgrade concentrate is channeled to specific collection points along the side of the deck, with middlings and tails directed to separate outlets.

Escopo de aplicação: Ideal for final concentration of gold from cyclone underflow, centrifugal concentrator tailings, or as a primary concentrator for coarse liberated gold. Effective on particle sizes typically between 100 malha e 1 milímetros.

Limitações: Not suitable for slimes (ultrafine particles below ~400 mesh). Performance is dependent on consistent feed density and particle size distribution. Requer um estábulo, level installation foundation.

6. CENÁRIOS DE APLICAÇÃO

[Hard Rock Gold Mill – Flotation Tailings Cleanup] Desafio: A milling operation was losing fine liberated gold to flotation tailings due to inefficient scavenging. Existing tabling was hampered by inconsistent feed from cyclones.

[Solução]: Two ST4422 shaking tables were installed in parallel to process cyclone underflow. Modular riffles were configured for fine gold recovery (~100 mesh).

[Resultados]: Field data shows an additional 0.8 g/ton gold recovered from tailings stream, generating a payback period of under nine months based on throughput.

[Aluvionar / Placer Operation – Primary Concentration] Desafio: A placer site needed a robust primary concentrator that could handle variable clay content without constant clogging or operator adjustment.

[Solução]: Implementation of shaking tables with enhanced wash water controls allowed operators to quickly adapt to changing feed conditions.

[Resultados]: Disponibilidade de plantas aumentada em 12%, and concentrate grade improved by 22%, significantly reducing downstream smelting charges.
