A washing plant and a head grinding machine are essential components in gold mining operations, each serving distinct purposes in the extraction and processing of gold ore. Here’s a breakdown of their roles:
1. Washing Plant (Gold Trommel or Scrubber)
– Purpose: Used to wash and separate gold-bearing gravel, clay, and sand.
– Components:
– Trommel Screen: Rotating cylindrical sieve that separates materials by size.
– Scrubber: Aggressively cleans sticky clay or dirt from rocks.
– Sluice Box/Gold Concentrator: Captures fine gold particles using gravity separation.
– Water Supply System: Ensures efficient washing and material flow.
– Used in: Alluvial/placer mining, where gold is found in loose sediment.
2. Head Grinding Machine (Ore Grinding Mill)
– Purpose: Crushes and grinds hard rock ore into fine particles to liberate gold for further processing.
– Types:
– Ball Mill: Uses steel balls to grind ore into powder.
– Rod Mill: Uses steel rods for grinding coarse ore.
– Hammer Mill/Stamp Mill: Older methods for crushing gold-bearing rock.
– Used in: Hard rock mining (lode deposits), where gold is embedded in quartz or other minerals.

Key Differences:
| Feature | Washing Plant | Head Grinding Machine |
|——————|————–|———————–|
| Function | Washing & separating loose material | Crushing & grinding hard rock |
| Used in | Placer mining | Hard rock mining |
| Output | Concentrated gravel/sand | Fine powdered ore |
| Next Step | Panning/sluicing | Cyanidation/leaching |
Integration in Gold Mining:
– If working with alluvial deposits, a washing plant (trommel) is primary.
– For vein/lode mining, a grinding mill processes crushed ore before leaching or smelting.
