Gold Gravity Separation Production Line

Gold Gravity Separation Production Line is a complete beneficiation plant designed for alluvial gold, placer gold and low-grade rock gold ore. It adopts physical gravity separation principle without chemical reagents, featuring environmental protection, low operating cost and high gold recovery rate. The whole line integrates trommel screening, centrifugal concentration, sluice box recovery, hammer crushing and 6S shaking table refining. Raw ore is classified into three size fractions (0-3mm, 3-10mm, >10mm) and processed by matched equipment to maximize gold recovery at each particle size stage, finally producing high-grade gold concentrate.

Step 1 — Primary Classification by Rotary Trommel Screen
Raw ore is fed into rotary trommel screen and divided into three fractions: 0-3mm fine fraction, 3-10mm medium fraction and >10mm coarse fraction.

Step 2 — Fine Fraction (0-3mm): Centrifugal Concentrator → 6S Shaking Table No.1
Fine slurry enters centrifugal gold concentrator for high-efficiency pre-concentration, then 6S shaking table further separates gold concentrate from tailings.

Step 3 — Medium Fraction (3-10mm): Fixed Gold Sluice Box → 6S Shaking Table No.2
Medium particles pass through fixed gold sluice box for coarse gold capture, then shaking table performs final concentration.

Step 4 — Coarse Fraction (>10mm): Hammer Crusher → Centrifugal Concentrator → 6S Shaking Table No.3
Oversize ore is crushed by hammer crusher to below 5mm, then enters centrifugal concentrator and shaking table for gold recovery.

Step 5 — Final Output
All three parallel circuits output high-grade gold concentrate; tailings are discharged uniformly for further treatment or stockpiling.

1. Three-stage Size Classification, Full Particle Size Coverage
Trommel screen divides raw ore into 0-3mm, 3-10mm and >10mm fractions, each matched with optimal recovery equipment, no gold loss at any size range.

2. Pure Physical Gravity Separation, Eco-friendly
No mercury, cyanide or chemical reagents required. Low environmental impact, easy to get mining permit, suitable for small & medium scale gold mines.

3. High Gold Recovery Rate
Centrifugal concentrator + sluice box + shaking table combined process achieves comprehensive recovery, especially effective for fine-grained and free-milling gold.

4. Low Investment & Operating Cost
Simple process flow, low power consumption, few wearing parts, easy operation and maintenance, fast return on investment.

5. Modular & Flexible Layout
Equipment can be arranged on fixed steel frame or mobile trailer, easy to transport and relocate between mining sites.

6. Customizable Capacity
Available from 5 t/h small scale to 200 t/h large scale, configured according to ore property, gold grade and site conditions.
