1. ABERTURA ACIONADA POR PAINPOINT

Are you managing gold recovery operations where declining ore grades and rising operational costs are squeezing your margins? Key challenges in material concentration and final recovery often include:

Inefficient Fine Gold Loss: Até 1530% of micronsized gold particles can be lost in traditional sluices or jigs, representing a direct revenue drain with every ton processed.
Alto consumo de água: In arid regions or sites with strict environmental permits, conventional concentration methods can require over 200 gallons per ton, creating significant sourcing and tailings management costs.
Dependência do Operador & Inconsistência: Manual tuning and operation of concentration equipment lead to variable recovery rates, making grade control and production forecasting difficult.
Downtime for Concentrate CleanUp: Frequent shutdowns to manually clean up concentrates from tables or spirals halt your primary processing circuit, reducing overall plant availability.

How do you capture the maximum value from every ounce without exponentially increasing your water, energia, and labor overhead? The solution lies in selecting the right primary concentration technology.

2. VISÃO GERAL DO PRODUTO: Knelson Concentrators for Primary Gold Recovery

A Knelson Concentrator is a batchtype, centrifugal gravity concentration device designed for the recovery of free gold and other heavy minerals from grinding circuit slurries. Its core function is to achieve high mass rejection while retaining over 95% of free gold particles, producing a highgrade concentrate for further treatment.

Fluxo de Trabalho Operacional:
1. Introdução ao feed: Slurry from the grinding mill cyclone underflow is introduced under pressure into the rotating cone.
2. Concentração Centrífuga: As the cone spins at high speed (até 200 Força G), centrifugal force pins heavy gold particles against the riffled lining.
3. Fluidized Bed Action: Continuous injection of fluidization water through the riffles creates a teetering bed, allowing dense gold to be trapped while lighter gangue material is flushed upward and out.
4. Retenção de concentrado: Gold accumulates in the riffles throughout the batch cycle (tipicamente 30120 minutos).
5. Descarga Automatizada: At cycle end, rotation stops and the concentrated heavy fraction is automatically flushed to a secure collection point.

Escopo de aplicação & Limitações:
Escopo: Ideal for recovering free (liberated) ouro >30 microns in size from grinding circuits. Highly effective as a primary concentrator in both hard rock and alluvial operations.
Limitações: Less effective on flat or flaky gold particles. O desempenho diminui em ultrafinos (<20 mícron) gold without specific modifications. Requires a consistent feed density and pressure for optimal operation.

6. CENÁRIOS DE APLICAÇÃO

Hard Rock Underground Mine Grade Control Challenge

Desafio: A Canadian underground operation faced erratic head grades, causing significant gold loss to tails when using fixedgravity circuits. Manual table performance was inconsistent across shifts.
Solução: Installation of two Knelson Concentrators in parallel on the primary ball mill discharge, with PLCcontrolled automated cycles synced to shift changes.
Resultados: Achieved an average free gold recovery rate of 96%. The consistent highgrade concentrate simplified downstream smelting scheduling. Annual recovered ounces increased by an estimated 8%, paying back the capital investment in under nine months. Gold Mining Equipment Makers Sourcing
