Targeted Custom Gold Ore Crushing Equipment: Engineered for HighValue Mineral Recovery

1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Le traitement du minerai aurifère présente des défis distincts et coûteux qui ont un impact direct sur vos résultats.. Standard crushing circuits often fall short, leading to operational inefficiencies that erode profit margins. Vivez-vous:

Metal Loss and Poor Liberation: Inefficient crushing can overgrind free gold or fail to properly liberate locked particles, causing valuable metal to report to tailings or become unrecoverable.
Excessive Abrasion & Coûts d'entretien: The high silica content (quartz) common in gold ores rapidly wears standard manganese steel components, leading to frequent downtime for liner changes and high consumable expenses.
Throughput Bottlenecks from Variable Feed: Dur, abrasive cap rock versus softer clayrich zones create inconsistent feed for your primary crusher, causing surges and reducing overall plant capacity.
Consommation d'énergie élevée par tonne: An inefficiently configured or improperly selected crusher for your specific ore hardness (par ex., lowgrade vs. highgrade, freemilling vs. réfractaire) wastes significant power without improving recovery.

Si ces problèmes vous semblent familiers, your operation requires a purposeengineered solution. The right custom gold ore crushing equipment is not a luxury—it is a fundamental requirement for optimizing recovery yield and controlling operational costs.

2. APERÇU DU PRODUIT

Notre solution technique est un CustomConfigured Gold Ore Crushing Circuit, typically centered on a heavyduty jaw crusher for primary reduction and a cone crusher for secondary crushing, specifically tailored to your ore characteristics and plant flow sheet.

Flux de travail opérationnel:
1. Réduction de la taille primaire: ROM ore is fed into a robust jaw crusher designed with optimal nip angle and stroke to handle hard, abrasive feed without bridging.
2. Scalping & Concassage fin: Primary crushed material is screened; oversize is conveyed to a secondary cone crusher with a chamber geometry matched to your target product size for optimal liberation.
3. Dimensionnement du produit: The final crushed product is screened to ensure consistent feed size (typically ½" to ¾") for downstream grinding mills, maximizing cyanide leach efficiency or gravity recovery.

Champ d'application & Limites:
Portée: Ideal for hard rock gold mining operations processing lode or vein deposits with moderate to high abrasiveness (par ex., quartz, granit). Effective for both freemilling and complex ores requiring fine liberation.
Limites: Non conçu comme une solution autonome pour les dépôts alluviaux/placeurs où le lavage et le criblage sont des processus principaux. Maximum feed size and capacity are determined by the specific model configuration.
