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

1. PAINPOINT DRIVEN OPENING

Processing goldbearing ore presents distinct and costly challenges that directly impact your bottom line. Standard crushing circuits often fall short, leading to operational inefficiencies that erode profit margins. Are you experiencing:

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 & Maintenance Costs: 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: Hard, abrasive cap rock versus softer clayrich zones create inconsistent feed for your primary crusher, causing surges and reducing overall plant capacity.
High Energy Consumption per Ton: An inefficiently configured or improperly selected crusher for your specific ore hardness (e.g., lowgrade vs. highgrade, freemilling vs. refractory) wastes significant power without improving recovery.

If these issues sound familiar, 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. PRODUCT OVERVIEW

Our engineered solution is a 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.

Operational Workflow:
1. Primary Size Reduction: 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 & Fine Crushing: 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. Product Sizing: 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.

Application Scope & Limitations:
Scope: Ideal for hard rock gold mining operations processing lode or vein deposits with moderate to high abrasiveness (e.g., quartz, granite). Effective for both freemilling and complex ores requiring fine liberation.
Limitations: Not designed as a standalone solution for alluvial/placer deposits where scrubbing and screening are primary processes. Maximum feed size and capacity are determined by the specific model configuration.
