1. ABERTURA ACIONADA POR PAINPOINT

Are you facing escalating operational costs and unpredictable downtime in your gold recovery circuit? The efficiency of your final recovery stage directly impacts your bottom line, yet many operations struggle with inconsistent yields, high reagent consumption, and laborintensive processes. These challenges manifest as measurable losses: every percentage point of unrecovered fine gold represents significant annual revenue left in the tails. Are you contending with frequent screen blockages that halt production for cleaning? Is your current process failing to capture micronsized particles, leading to visible gold loss in your tailings dam? Managing these inefficiencies often requires additional manpower and complex chemical balances, driving up both operational expenditure and environmental management costs. The central question for plant managers is clear: how can you achieve maximum payable gold recovery with greater operational consistency and lower total cost of ownership?

2. VISÃO GERAL DO PRODUTO

O {{keyword}} é uma alta capacidade, continuous concentration device designed for the efficient recovery of free gold, particularly fine and micronsized particles, from grinding circuit discharges and leach feed. It operates on a patented centrifugal separation principle, replacing or augmenting traditional batchoperated concentrators.

Fluxo de Trabalho Operacional:
1. Introdução ao feed: Slurry from the grinding mill or cyclone underflow is evenly distributed into the rotating bowl of the {{keyword}}.
2. Concentração Centrífuga: HighG forces pin heavy gold particles against the collection grooves, while lighter gangue material is fluidized and washed out.
3. Descarga Contínua: Concentrated heavy material is automatically discharged at programmed intervals into a secure collection vessel without interrupting the feed flow.
4. Tailings Removal: Depleted slurry (tails) exits the unit continuously, ready for downstream processing or reporting to tails storage.

Escopo de aplicação: Ideal para recuperar ouro grátis >50 microns in size within closedcircuit milling operations, as a primary concentrator for alluvial/heap leach feed preconcentration, or as a scavenger device ahead of leaching/CIL tanks.

Limitações: Not suitable for primary comminution; efficiency diminishes on slimesdominated feeds (<10 mícrons) without preclassification; requires a consistent feed density and pressure for optimal performance.
