1. ABERTURA ACIONADA POR PAINPOINT

Are you facing persistent operational bottlenecks and rising costs in your gold recovery circuit? The efficiency of your final concentration stage directly impacts profitability and metal recovery rates. Common challenges with conventional separation equipment include inconsistent concentrate grades leading to downstream processing inefficiencies, excessive mechanical downtime for maintenance and screen replacement, and significant loss of fine gold particles to tailings due to inadequate separation dynamics. Essas questões se traduzem em perdas mensuráveis: every percentage point of unrecovered gold represents substantial revenue forfeited, while unplanned downtime can cost thousands per hour in lost processing capacity. Are you currently evaluating solutions to enhance the precision and reliability of your final gravity concentration stage? Can your operation afford the ongoing consumable costs and metal loss associated with outdated separation technology?

2. VISÃO GERAL DO PRODUTO

This product line comprises a range of CEMarked Gold Concentrating Tables, specifically engineered for the highefficiency gravity separation of gold from heavy mineral concentrates. As a final concentration device, it operates on the principle of differential particle movement across a riffled deck under the influence of water flow and mechanical vibration.

Fluxo de Trabalho Operacional:
1. Introdução ao feed: A prepared slurry of primary concentrate is evenly distributed along the upper edge of the inclined table deck.
2. Estratificação & Separação: As the deck oscillates, particles stratify by density; heavier gold particles settle into the riffles, while lighter gangue materials are suspended.
3. Longitudinal Transport: Continuous table motion conveys trapped heavy minerals along the riffles toward the concentrate discharge end.
4. CrossWash Separation: Controlled wash water flows across the deck, carrying away middensity materials to middlings and light tails.
5. Coleção: Separated products are discharged into distinct launders for highgrade concentrate, farinha média (for recirculation), and tailings.

Escopo de aplicação & Limitações:
Escopo: Ideal for upgrading concentrates from centrifugal concentrators, espirais, or jigs; recovering fine gold (+100 malha); and final cleaning before smelting or intensive leaching.
Limitações: Requires a wellclassified feed (tipicamente 10 malha) para desempenho ideal. Not a primary recovery unit for whole ore; feed must be preconcentrated. Performance is influenced by feed density, distribuição de tamanho de partícula, and water quality.
