2.Application Gold Ore Processing Equipment

• Hard-Rock Processing Plants: Acts as the core equipment in gravity circuits for roughing, scavenging, or cleaning ground ore to maximize total recovery.

• Pre-concentration: Removes bulk gangue before downstream processes like flotation or cyanidation, reducing the volume to be treated and improving overall economic efficiency.

• Fine Gold Capture: Exceptionally efficient at recovering fine gold particles in the 0.02–0.5 mm range, outperforming many traditional methods.

• Small to Medium Mines: Ideal due to its relatively simple structure and low capital/operating costs.

• Tailings Re-treatment: Used to recover residual fine gold from historical tailings ponds.

3.Working Principle  Gold Ore Processing Equipment

• Feeding and Wetting: The ore pulp (typically 15–30% solids) resulting from crushing and grinding is distributed uniformly onto the inclined deck.

• Stratification and Transport: The deck is driven by a mechanism (such as a crank-and-link or electromagnetic drive) that produces a differential reciprocating motion. Simultaneously, a thin film of transverse wash water flows across the deck.

• Density Separation: Under the combined forces of mechanical motion and water flow, particles stratify by density. The densest gold particles settle to the bottom-most layer against the deck and migrate diagonally toward the concentrate end.

• Product Discharge:

  • Concentrate: High-grade gold is discharged from the concentrate port at the end of the deck.

  • Middlings & Tailings: Lower-density materials are discharged from the middle and end sections.

  • Optimization: Separation can be fine-tuned by adjusting the longitudinal slope, transverse tilt, water flow, and vibration frequency/amplitude.

4. Advantages  Gold Ore Processing Equipment

• High Recovery Rate: For well-liberated hard-rock gold, recovery rates can reach 85%–95%, with superior performance in capturing fine and ultra-fine gold.

• Low-Cost Operation: Compared to chemical-heavy processes, it consumes very little energy (typically 1–5 kW motors) and zero reagents, drastically lowering OPEX.

• Environmentally Friendly: Uses only water and physical force. It eliminates the need for toxic chemicals like cyanide or mercury, minimizing environmental risk.

• Intuitive & Durable: The separation process is visible on the deck, allowing operators to monitor performance in real-time. Maintenance requirements are minimal compared to complex flotation cells.

• High Enrichment Ratio: Capable of concentrating gold from a few grams per ton in the feed to thousands of grams per ton in the concentrate.
