Not All That Glitters is Gold: Are You Maximizing Your Fine Gold Recovery?
In mineral processing, profit is captured in the margins. For operations focused on gold, tungsten, tin, and other heavy minerals, the final concentration stage is where value is won or lost. Traditional methods often lead to significant losses of fine gold particles, leaving tangible revenue trapped in your tails. Inefficient separation means you're not just losing product; you're eroding your return on investment.
Introducing the Aurora GT-200 Gold Shaker Table—a precision-engineered solution designed to achieve unparalleled recovery rates of fine gold and heavy minerals, transforming your final processing stage from a cost center into a profit-maximizing asset.
What is the Aurora GT-200 and How Does It Work?
The Aurora GT-200 is a mechanized concentration table that separates materials based on particle density through a combination of precisely calibrated shaking motion and strategic water flow. It is the culmination of decades of engineering refinement for modern, high-demand processing plants.
The Precision Separation Workflow:
- Feed Preparation: A regulated slurry of classified feed material (typically -1mm) is introduced at the head of the table.
- Stratification and Separation: As the table deck oscillates rapidly back and forth (the "shake"), denser particles settle to the bottom of the particle bed. Simultaneously, a thin film of water flows across the deck's riffled surface (the "flow"), fluidizing the material.
- Differential Transport: This is where the magic happens. The reciprocal motion transports denser particles (e.g., gold) perpendicularly across the water flow towards the concentrate end. Lighter gangue materials are carried by the water stream and discharged as tails.
- Precise Product Collection: The process results in three distinct product streams:
- Concentrates: A high-grade band of heavy valuable minerals collected at the end of the table.
- Middlings: A medium-grade product that can be recirculated for further processing.
- Tails: The waste material, now stripped of its valuable content.
Engineered for Performance: Core Features That Deliver ROI
Why settle for adequate when you can have optimal? The GT-200 is built with features that directly impact your bottom line.
- Micro-Adjustable Deck Action: A patented asymmetrical motion mechanism allows operators to fine-tune the shake profile—from a sharp, aggressive stroke for coarse gold to a gentle, long stroke for ultra-fine recovery. This ensures optimal performance for varying feed conditions.
- Lineage® Composite Riffle System: Our deck is surfaced with an ultra-wear-resistant, fiber-reinforced composite material. Unlike rubber or PVC, Lineage® provides superior durability against abrasion and an ideal friction coefficient for particle bedding, significantly outlasting competitors and reducing lifecycle costs.
- Variable-Frequency Drive (VFD) Control: Total command is at your fingertips. The integrated VFD allows operators to digitally adjust stroke rate and intensity in real-time without stopping production, enabling rapid response to changes in feed grade or particle size.
- Modular, Low-Maintenance Design: Built with serviceability in mind. The direct-drive mechanism eliminates complex gearboxes and reduces moving parts by 40% compared to legacy models. This translates to higher uptime and dramatically lower maintenance requirements.

Case Study Snapshot:
A mid-tier gold operation in West Africa was struggling with >15% fine gold loss in their tailings from their existing shaking tables. After installing a bank of three Aurora GT-200 units as scavengers, they reported a measurable increase in overall recovery of 6%, paying back their capital investment in less than five months of operation..jpg)

Frequently Asked Questions (FAQ)
What particle size range is the GT-200 most effective for?
The GT-200 excels in recovering particles between 100 microns and 2 millimeters. Its adjustable stroke makes it particularly effective for sub-150 micron "ultra-fine" gold that often escapes traditional sluices and jigs.
How complex is the installation and operational setup?
The unit ships as a pre-assembled module requiring only connection to power, water, and feed/discharge lines. Our comprehensive documentation and optional startup support ensure your team can be operational swiftly.
What are your lead times?
Standard lead times are currently 8-10 weeks from receipt of order. Expedited manufacturing may be available.
Do you offer wear parts and technical support?
A global network of distributors ensures ready access to genuine wear parts like deck surfaces and drive components. Remote technical support is available to assist with optimization troubleshooting
