1. PAINPOINT DRIVEN OPENING

Are you facing persistent bottlenecks in your gold recovery circuit that directly impact your bottom line? Common operational challenges with gold mining equipment include inconsistent feed rates leading to process instability, premature wear of critical components in abrasive slurry environments causing unplanned downtime, and inefficient separation resulting in measurable gold losses to tailings. These issues translate into quantifiable costs: hours of lost production during component changeouts, ongoing expenditure on replacement parts, and the permanent loss of recoverable value. How do you stabilize your operation to achieve predictable throughput, extend the service life of highwear items, and maximize recovery rates from every ton of ore processed? The solution lies in specifying equipment engineered specifically for the demanding lifecycle of a gold mining operation.

2. PRODUCT OVERVIEW

This product line encompasses heavyduty, modular gold mining equipment designed for the concentration, separation, and recovery of gold from alluvial and hard rock sources. The operational workflow is engineered for integration into existing plants or new installations:

1. Feed Preparation: Scalping or scrubbing modules remove oversized material and clays to ensure optimal downstream processing.
2. Gravity Concentration: Dense media separation or centrifugal concentrators isolate highspecificgravity gold particles from gangue material.
3. Separation & Collection: Specialized sluices, jigs, or shaking tables provide final concentration into a clean heavy mineral fraction.
4. Security & Handling: Integrated locking mechanisms and streamlined collection points secure the valuable concentrate.

Application scope includes primary ore processing, scavenging from milled product, and tailings reprocessing. Key limitations involve feed particle size compatibility; optimal recovery is achieved within specified size ranges, and extremely fine (<10 micron) liberated gold may require supplementary chemical processes.

Alluvial Placer Operation in West Africa

Challenge: A largescale placer mine experienced significant gold losses in fine (80 mesh) fractions using traditional sluices, alongside high maintenance downtime due to abrasive sand wear on equipment.
Solution: Implementation of a multistage circuit featuring lowwater consumption scrubbers followed by a series of highG centrifugal concentrators as the core gold mining equipment.
Results: Plant recovery efficiency increased from an estimated 88% to 95%. Liner replacement intervals extended from every 6 weeks to every 4 months. Total water consumption was reduced by over half.

Hard Rock Tailings Reprocessing Project
