How to Choose the Right Alluvial Mining Methods for Your Gold Plant?

/in /by

Alluvial gold mining is one of the most efficient methods for extracting gold from riverbeds, floodplains, and shallow deposits. To maximize recovery, a well-designed alluvial gold processing plant must be equipped with the right set of machines.

A typical configuration includes:

  • Trommel screen  Drum screen
  • Gold concentrator
  • Sluice box
  • Belt conveyor
  • Trough feeder
  • Jaw crusher
  • Hammer crusher
  • Shaking table
  • Gold smelting furnace

Step-by-Step Alluvial Gold Mining Process

1. Feeding and Screening

The process begins with the alluvial raw ore fed into a trommel screen.

  • The trommel washes away clay and separates gravel or stone.
  • Oversized material (+6mm) is sent to the jaw crusher for crushing.
  • Smaller slurry (<6mm) flows to slurry pumps for further processing.

Mobile trommel screens are often preferred for flexibility, while stationary designs are suitable for permanent operations.

2. Crushing and Grinding

  • Jaw crusher: Handles stones up to 210mm, reducing them to 40–60mm.
  • Hammer crusher: Further reduces size to <10mm.
  • Wet pan mill: Grinds particles to <1mm, releasing gold locked inside the stone.

This staged crushing and grinding ensures efficient liberation of gold-bearing material.

3. Concentration and Separation

  • Slurry pumps transport <6mm material to the gold concentrator, where initial gold recovery takes place.
  • Concentrates from the concentrator are refined on shaking tables, which separate fine gold particles based on density.
  • Each concentrator is paired with a sluice box (for tailings) and two shaking tables to maximize recovery.

4. Gold Smelting

All concentrates recovered from the shaking tables are collected and processed in a gold smelting furnace, producing pure gold bars ready for market.

Equipment Performance and Capacity

  • Crushing capacity: approx. 5 tons per hour
  • Grinding and gold separation capacity: approx. 3 tons per hour
  • Mobile trommel screens with wheels add flexibility for operations across multiple mining sites.
