Alluvial Gold Ore Gravity Separation Solutions

Alluvial Gold Ore Gravity Separation Solution

I. Program Overview

Alluvial gold ore is an important gold resource, which is mainly recovered by physical methods such as screening and gravity separation. This alluvial gold ore beneficiation solution adopts highly efficient and energy-saving gravity beneficiation process, and provides production line solutions with large processing capacity for alluvial gold mines of different sizes, which ensures a high recovery rate while minimizing the operating cost and ensuring the maximization of the return on investment.

Gravity Separation Process for Alluvial Gold Ore

1. Pre-treatment stage

   • Feeding: use vibrating feeder or belt conveyor to evenly transport the ore

   • Screening and debris removal:

     • Tumbler screen to remove large waste rock and miscellaneous materials

     • Processing capacity: 10-300t/h

   • Ore washing and desliming:

     • Rotary scrubber removes clay and impurities and improves ore looseness

2. Gravity roughing (core stage)

   • Jigger:

     • Processes coarse-grained gold (>0.5mm)

     • Stroke 8-12mm, 200-300 strokes/minute

     • Large processing capacity, suitable for continuous production of medium and large alluvial gold mines

   • Centrifugal concentrator:

     • Processing fine-grained gold (0.02-1mm)

     • Outstanding effect on the recovery of fine-grained gold

   • Spiral chute:

     • Powerless design, very low energy consumption

     • Suitable for small and medium sized plants with low maintenance costs

   • Drum chute:

     • Simple process, low investment cost

     • Flexible adjustment of stroke and frequency

3. Selection and purification

   • Shaking table:

     • Further purification of jigger concentrate

     • Processing capacity: 0.5-2t/h

4. Tailings treatment

   • Thickener to increase the concentration of tailings (60%-70%)

   • Tailings water content <15% after filter press dewatering

Third, the core equipment configuration

Fourth, alluvial gold ore gravity separation program advantages

• ✅ High recovery rate: jigging + centrifugal combined process, covering 0.02-30mm gold particles

• ✅ Low energy consumption: equipment matching optimization, low energy consumption

• ✅ Economic investment: simple process flow, reasonable investment in equipment

• ✅ Environmental protection and energy saving: no chemical additives, water recycling

• ✅ Strong adaptability: process parameters can be flexibly adjusted according to the characteristics of the ore.

V. Typical Configuration

1. High-efficiency recovery type

   • Flow: trommel → jigger → shaking table

   • Characteristics: high concentrate grade, suitable for ore bodies with coarse gold grains.

2. Large processing capacity type

   • Flow: trommel → jigger → centrifuge

   • Characteristics: Processing capacity above 100t/h, taking recovery rate and cost into consideration.

3. Simple and economic type

   • Flow: trommel screen → drum chute → shaking table

   • Characteristics: small investment and quick results, suitable for small-scale processing plant
