If you are a mining engineer, plant manager, or procurement specialist involved in gravity separation—particularly for gold, tin, tungsten, or other heavy minerals—you already know that every component in your processing circuit impacts the bottom line. One often overlooked but critical component is the shaking table carpet (also known as a gold mat, deck covering, or sluice box carpet).
This consumable wears down over time. Its performance directly determines how effectively your shaking table captures fine, high-value particles. Choosing the right one is not just about replacing what you have—it’s an opportunity to improve recovery rates, reduce gold loss, and extend equipment life.
In this guide, we’ll cover what a shaking table carpet is, what to look for when buying one, common applications, and why Annilte’s premium carpets are trusted by miners across Africa and beyond.
What is a Shaking Table Carpet?
A shaking table carpet—also referred to as a miner’s moss, gold mat, or sluice box carpet—is a specialized synthetic mat placed on the deck of a shaking table or within sluice boxes . Its purpose is simple but crucial: create a textured surface that traps heavy mineral particles (like gold) while allowing lighter waste material to wash away during the gravity separation process.
The design and material of the carpet are critical. The surface material is typically PE (polyethylene) , known for its wear resistance and durability. The backing is often made of PA (polyamide/nylon) to provide stability, strength, and resistance to stretching . Standard specifications commonly include:
- Thickness: 24mm, 26mm, or 27mm .
- Roll Size: 1m x 15m or 1m x 16m .
- Colors: Green (best for alluvial gold recovery) and Yellow (optimized for rock gold) .
Why the Right Shaking Table Carpet Matters
1. Capturing Fine Gold and Heavy Minerals
In gravity separation, the goal is to maximize the recovery of valuable particles. The right carpet creates low-pressure zones and turbulence that trap fine gold particles (flour gold) and small nuggets that other methods might miss . If your carpet is worn, improperly sized, or has the wrong texture for your feed material, you are essentially allowing valuable minerals to flow into your tailings.
2. Durability in Harsh Mining Conditions
Mining environments are harsh. Your equipment must withstand continuous operation, abrasive materials, and variable water conditions. High-quality shaking table carpets are engineered with materials like PE and PA to provide exceptional wear resistance and longevity . This reduces the frequency of replacement, lowering your cost per ton processed.
3. Suitability for Different Ore Types
There is no “one-size-fits-all” carpet.
- Alluvial Deposits: Green carpets are typically recommended for alluvial gold recovery, effectively capturing particles ranging from 1mm to 6mm .
- Rock Gold: Yellow carpets are the preferred choice for recovering fine gold particles from crushed rock gold ore .
This specificity means you can tailor your consumables to match your specific ore characteristics and processing goals.
Common Applications in Mineral Processing
- Tailings Recovery: One of the most effective uses for a shaking table carpet is recovering gold from the tailings of centrifugal concentrators. Installing a high-quality carpet on a shaking table downstream of a concentrator can significantly reduce overall gold losses .
- Alluvial Gold Processing: In alluvial operations, carpets are typically installed on sluice boxes following the trommel screen. They efficiently capture gold from the initial wash and screening stage .
- Rock Gold Fine Recovery: For hard rock operations, a shaking table equipped with a suitable carpet provides a reliable final cleaning stage for gravity concentrates.
What to Look for in a Shaking Table Carpet Supplier
When sourcing your shaking table carpets, consider these factors beyond just the price per roll:
- Material Quality and Construction: Ensure the carpet is manufactured from high-grade PE and PA materials. The backing should be securely bonded to prevent delamination .
- Customization Options: Every plant has different needs. Can the supplier offer different thicknesses, sizes, or colors? A supplier with strong R&D capabilities can adapt products to your specific equipment .
- Consistent Supply Chain: In mining, downtime is expensive. Your supplier should have sufficient production capacity and raw material inventory to ensure on-time delivery, even for emergency orders.
- Relevant Certifications: Look for suppliers who hold ISO and other relevant quality certifications .
