Is Your Current Gold Recovery Equipment Costing You 1520% in Lost Yield?

Every plant manager in hard rock or alluvial gold operations faces the same set of bottlenecks: declining ore grades, rising energy costs, and the constant pressure to increase recovery rates without expanding footprint. A standard ball mill and CIL circuit can lose up to 15% of fine gold to tailings due to inefficient liberation or poor contact time. Your engineering contractors are likely spending 30% of their budget on retrofitting offtheshelf equipment that wasn’t designed for your specific gangue mineralogy.

How much downtime are you accepting from equipment that wasn’t engineered for continuous 24/7 operation? Are your current suppliers delivering the metallurgical guarantees your project financing requires?

Product Overview: CustomEngineered Gold Processing Solutions

As an industrial gold mining equipment contract manufacturer, we provide purposebuilt machinery for the complete gold recovery workflow—from primary crushing to final doré bar production. Our equipment is designed for both freemilling and refractory ore bodies.

Operational Workflow:
1. Primary & Secondary Crushing: Heavyduty jaw and cone crushers with automated gap adjustment to achieve P80 of 1215mm.
2. Grinding & Classification: Overflow ball mills or SAG mills paired with hydrocyclone clusters for optimal grind size (P80 of 75150 microns).
3. Gravity Concentration: Centrifugal concentrators and jigs for coarse gold recovery (up to 60% recovery before leaching).
4. Leaching & Adsorption: Highefficiency carboninleach (CIL) or carboninpulp (CIP) tanks with interstage screening.
5. Elution & Regeneration: Acid wash columns, electrowinning cells, and carbon regeneration kilns.

Application Scope: Suitable for openpit and underground operations processing 500 to 5,000+ tonnes per day. Limitations: Not designed for ultrafine (<10 micron) refractory ores requiring pressure oxidation or bioleaching without pretreatment circuit integration.

FAQ

Q: Can your equipment handle ore with high arsenic or sulfide content?
A: Yes. We offer stainless steel and rubberlined options for corrosive environments. For sulfides, we recommend our preaeration tank design to reduce cyanide consumption by up to 30%.

Q: What is the typical lead time for a 1,000 TPD plant?
A: Standard lead time is 2024 weeks from order confirmation. This includes engineering, fabrication, and factory acceptance testing. Expedited delivery (16 weeks) is available for an additional 10% premium.

Q: Do you provide metallurgical testing before equipment design?
A: Yes. We require a 50kg ore sample for benchscale testing (gravity, leaching, settling). This data is used to guarantee recovery rates in your contract. Testing costs are credited toward the final equipment price.

Q: How does your equipment handle power fluctuations common in remote mining sites?
A: All VFDs and control systems include builtin surge protection and brownout ridethrough capability (up to 2 seconds). We also offer optional diesel generator synchronization packages.

Q: What is the expected lifespan of the CIL tank agitators?
A: With proper maintenance (annual bearing replacement, quarterly gearbox oil analysis), the agitator assembly has a design life of 10+ years. The tank liners typically require replacement every 57 years depending on abrasion.

Q: Can you retrofit your equipment into an existing plant layout?
A: Yes. Our engineering team performs a 3D laser scan of your existing facility to ensure fit. We have completed 15+ retrofits where space was constrained to less than 2 meters between existing tanks.

Q: What are the warranty terms for the carbon regeneration kiln?
A: The kiln shell carries a 5year warranty against thermal fatigue. The refractory lining is warranted for 2 years. The burner system carries a 3year warranty on all components.
