50 TPH Gold Grinding Plant with Wet Pan Mill in Sudan

Ore Feeding & Crushing:

• Raw ore is fed by a vibrating feeder.
• A small jaw crusher crushes the ore to below 20mm to provide suitable feed size for the Wet Pan Mill.

Concentration & Upgrading:

• The slurry discharged from the Wet Pan Mill already contains a primary concentrate.
• This slurry is then passed over a Gold Carpet / Sluice Box to trap the fine gold particles and further upgrade the concentrate.
• The tailings from the sluice box are discharged to the tailings pond.

Water Circulation & Power:

• A simple settling pond system allows for water recycling, minimizing consumption.
• The plant is typically powered by a diesel generator, making it ideal for remote sites with no grid power.

Wet Grinding & Amalgamation (Optional):

• The crushed ore is mixed with water and continuously fed into the Wet Pan Mill.
• The Wet Pan Mill performs multiple functions: it grinds the ore to a fine slurry (typically to 1-2mm), simultaneously mixing and homogenizing the pulp.
• Core Function: The heavy iron rollers grind and squeeze the ore, liberating gold particles. Due to its high density, the gold settles at the bottom and gets concentrated.
• (Optional) For direct smelting, a small amount of mercury can be added inside the pan to amalgamate free gold during the grinding process (Note: This practice is being phased out due to environmental concerns and is not recommended).

Concentrate Handling & Smelting:

• The concentrate collected from the bottom of the Wet Pan Mill and from the gold carpet is carefully panned or cleaned using a small Shaking Table to remove residual impurities.
• The final high-grade concentrate is dried and smelted in a Portable Smelting Furnace to produce gold doré bars.
