1. PAINPOINT DRIVEN OPENING

Managing gold recovery operations presents persistent challenges that directly impact profitability. Are you facing escalating costs and operational inefficiencies? Common pain points include inconsistent feed material leading to variable recovery rates, excessive water consumption in arid regions, high maintenance downtime from abrasive ore wear, and the safety risks associated with manual concentrate handling. These issues translate to lost revenue—every percentage point of unrecovered gold and every hour of unscheduled downtime represents a significant financial drain. How can you stabilize your process, reduce operational expenses, and maximize yield from every ton of ore? The solution lies in purposeengineered, reliable gold mining equipment.

2. PRODUCT OVERVIEW

This product line encompasses heavyduty, modular gold mining equipment designed for the rigorous concentration and recovery of placer and hard rock gold. The operational workflow is engineered for continuous processing: (1) Primary screening and classification to remove oversize material, (2) Highvolume feed into the primary concentration system, (3) Efficient gravitybased separation of gold from gangue material, (4) Secure collection of concentrates for further refinement. This equipment is applicable for medium to largescale alluvial operations, hard rock plant preconcentration, and tailings reprocessing projects. It is not designed for ultrafine (sub50 micron) gold recovery without supplementary circuit design or as a standalone chemical processing unit.

6. APPLICATION SCENARIOS

Alluvial Placer Operation in West Africa | Challenge: Highly variable clay content causing frequent blockages in traditional sluices, leading to constant operator oversight and lost fine gold. Solution: Implementation of a trommelscrubber module feeding into our modular gold mining equipment with integrated grizzly and spray bars. Results: Blockage incidents reduced by over 90%, allowing one operator to monitor multiple lines. Recovery rates improved by an estimated 8% on sub100 mesh gold due to improved scrubbing and retention time.

Hard Rock Tailings Reproject in North America Challenge Lowgrade historical tailings requiring highvolume processing with a very tight water usage permit Solution Deployment of a highthroughput stack of our gold mining equipment configured with specific matting for fine gold recovery within a fully closedwater circuit Results System processes over 2，000 tons per day meeting all environmental compliance standards Project payback was achieved in under14 months based on recovered value
