1. PAINPOINT DRIVEN OPENING

Are your gold processing operations constrained by inconsistent feed, high maintenance costs, and suboptimal recovery rates? The primary crushing stage sets the tone for your entire recovery circuit. Inefficient or unreliable bespoke gold ore crushing equipment directly impacts your bottom line through:
Unplanned Downtime: Frequent breakdowns from abrasive, highsilica gold ores halting your milling circuit.
High Operating Costs: Excessive energy consumption per ton crushed and rapid wear part replacement consuming maintenance budgets.
Recofficiency Losses: Poorly sized feed from inadequate crushing causing poor leach pad percolation or inefficient grinding mill feed.
Inflexibility: Standard crushers struggling with variable ore hardness or claybound materials, creating bottlenecks.

Is your operation sacrificing throughput and profitability due to a crusher that isn't engineered for your specific ore body's challenges?

2. PRODUCT OVERVIEW

Our solution is engineered bespoke gold ore crushing equipment: customconfigured stationary or modular primary and secondary crushing plants designed for the unique characteristics of hard rock gold deposits. The operational workflow is optimized for precious metal processing:

1. Primary Size Reduction: Rugged jaw or gyratory crushers accept runofmine (ROM) ore, reducing it to a manageable size for secondary processing.
2. PreScreening & Scrubbing: Integrated scalping and scrubbing modules remove fines and break up claybound agglomerates before secondary crushing, enhancing efficiency.
3. Secondary Crushing & Control: Cone crushers or highpressure grinding rolls (HPGR) set to produce an optimal, consistent product size for your downstream ball mill or leaching stack.
4. Material Handling Integration: Custom conveyor systems transport crushed material while minimizing dust generation and spillage.

Application Scope: Ideal for midtolargescale gold mining operations targeting lode or vein deposits with variable hardness (e.g., quartzite, greenstone). Includes solutions for both carboninleach (CIL) and heap leach operations.

Limitations: Not designed for alluvial/placer mining operations requiring minimal crushing. Maximum economic viability requires a defined minimum reserve tonnage and grade.

6. APPLICATION SCENARIOS

HighGrade Underground Mine Transitioning to Open Pit | Challenge: Existing crusher could not handle the increased throughput and more abrasive ore from the new pit, creating a bottleneck that limited mill feed.| Solution: Implementation of a bespoke primary gyratory crusher station with an integrated apron feeder and heavyduty scalper to manage direct truck dump from the pit.| Results: Sustained throughput of 1,200 tph achieved within one week of commissioning; wear part lifecycle matched predictive models within 5%.

Remote Heap Leach Operation with ClayBound Ore | Challenge: Clay content in the ore caused frequent plugging and bridging in the standard crushing circuit, leading to daily downtime for manual clearing.| Solution: Deployment of a bespoke crushing circuit featuring a primary jaw crusher followed by a rotary scrubber module before secondary cone crushing.| Results: Plugging incidents reduced by over 90%; produced a consistently fractured oxide ore ideal for heap stacking, improving overall leach recovery by an estimated 5%.
