1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are escalating operational costs and unpredictable downtime eroding your gold mining operation's profitability? Key challenges in material handling and primary recovery often include:
High PreConcentration Losses: Inefficient initial screening results in fine gold reporting to tailings or requiring intensive downstream processing, impactant directement les taux de récupération.
Temps d'arrêt excessif pour la maintenance: Frequent clogging and wear in feed systems halt entire processing lines, coûtant des milliers de dollars par heure en perte de production.
High Water and Energy Consumption: Inefficient separation technology demands excessive water volume and pump horsepower, inflating both utility costs and environmental management expenses.
Gestion incohérente des aliments: Variable feedstock from the pit causes surges and bottlenecks, preventing optimal, steadystate operation of your recovery circuit.
Opération à forte intensité de main d'œuvre: Reliance on manual adjustment and monitoring increases labor costs and introduces human error into a critical recovery stage.

Is your operation equipped to maximize yield from the first stage of recovery while controlling the total cost of ownership? The efficiency of your primary concentration technology is a decisive factor.

2. APERÇU DU PRODUIT: Jig Concentrators for Gold Recovery

UN {{mot-clé}} is a gravity separation device designed for the highcapacity, continuous concentration of heavy minerals, specifically free gold, from crushed ore. It operates on the principle of pulsating water through a bed of material to stratify particles by density.

Flux de travail opérationnel:
1. Présentation du flux: Crushed, screened ore slurry is evenly distributed across the machine's bed.
2. Pulsation & Stratification: A precisely controlled hydraulic or mechanical pulse pushes water upward through the ore bed, fluidizing it. Denser gold particles settle to the bottom (ragging layer), while lighter gangue material rises to the top.
3. Continuous Separation: The stratified bed is continuously harvested; concentrated heavy material (goldbearing concentrate) is extracted through a discharge gate, while tailings overflow at the top of the bed.

Champ d'application & Limites:
Idéal pour: Highvolume primary recovery of liberated free gold (>50 microns), alluvial/elluvial deposits, and as a rougher concentrator ahead of finer gravity circuits or flotation. Effective on both virgin ore and for scavenging from milled tails.
Limites: Not suitable for recovering ultrafine or chemically bound (réfractaire) gold without prior liberation. Performance is dependent on consistent feed size distribution and appropriate ragging material selection.
