1. PAINPOINT DRIVEN OPENING

Are unplanned equipment failures and inconsistent performance derailing your gold recovery targets? Operational data from hard rock and alluvial sites consistently points to three costly challenges: premature component wear in abrasive slurry environments, leading to excessive spare parts costs and unscheduled downtime; inefficient material classification, resulting in lost fine gold and reduced overall plant yield; and complex calibration procedures that extend commissioning time and increase labor overhead. These issues directly impact your bottom line through lost production hours and suboptimal recovery rates. How can you ensure your gravity separation and concentration equipment is not the bottleneck in your operation? What would a 15% reduction in maintenancerelated downtime mean for your annual output? The solution begins with rigorous, factorybased validation under simulated realworld conditions.

2. PRODUCT OVERVIEW

This document details our comprehensive Factory Acceptance Testing (FAT) Protocol for gold mining concentration equipment, specifically centrifugal concentrators, shaking tables, and jigs. This is not a simple operational check. Our FAT is a rigorous, datadriven validation process designed to derisk your capital investment before equipment ships to site.

The operational workflow involves: 1) Component Integrity Verification, where individual parts are inspected against material certifications for wearresistant alloys; 2) SubSystem Performance Testing, including hydraulic systems, drive assemblies, and control panels under load; 3) Full Assembly DryRun, assessing mechanical function, vibration, noise, and alignment; 4) Live Material Test, using standardized ore or synthetic feedstock to benchmark recovery efficiency against design specifications; and 5) Data Package Compilation, delivering certified test reports for each unit.

This protocol applies to new equipment builds and major refurbishments. Its primary limitation is that it simulates plant conditions but cannot replicate the exact feed variability or environmental factors of a specific mine site; it is a critical baseline for performance guarantee validation.

3. CORE FEATURES

6. APPLICATION SCENARIOS

Alluvial Gold Operation, West Africa | Challenge: Multiple centrifugal concentrators from different suppliers showed wildly variable field performance, causing inconsistent recovery across the plant fleet and making process optimization impossible. |

Solution: A procurement mandate was established requiring all new concentrators to pass a standardized Factory Acceptance Test with live feedstock using sitespecific alluvial material.| Results: PostFAT implementation, the variance in recovery between units dropped from ±18% to ±4%. Plant managers could standardize operating parameters across the entire fleet, increasing overall site recovery by an average of 11%.
