Gold processing equipment for a mining plant varies depending on the scale of operations, the type of ore (alluvial or hard rock), and the desired recovery efficiency. Below is a breakdown of essential equipment used in gold processing plants:
1. Crushing & Grinding Equipment
– Primary Crusher (Jaw Crusher, Gyratory Crusher) – Breaks large ore into smaller pieces.
– Secondary Crusher (Cone Crusher, Impact Crusher) – Further reduces ore size.
– Ball Mill / SAG Mill – Grinds crushed ore into fine powder for better gold liberation.
2. Gravity Separation Equipment
– Shaking Tables – Separates gold from lighter materials using gravity.
– Spiral Concentrators / Sluice Boxes – Recovers free gold from alluvial deposits.
– Centrifugal Concentrators (Knelson, Falcon) – Enhances fine gold recovery from crushed ore.
3. Flotation Equipment (for sulfide ores)
– Flotation Cells / Columns – Separates gold-bearing sulfides from waste rock using chemicals and air bubbles.
4. Leaching & Adsorption (for refractory ores)
– CIL/CIP Tanks (Carbon-in-Leach/Carbon-in-Pulp) – Dissolves gold using cyanide and recovers it with activated carbon.
– Heap Leaching Pads – Used for low-grade ores where cyanide solution percolates through stacked ore to extract gold.
5. Smelting & Refining Equipment
– Electrowinning Cells – Extracts gold from solution via electrolysis.
– Induction Furnace / Crucible Furnace – Melts gold concentrate into doré bars.

ng System (Aqua Regia, Miller Process) – Purifies gold to 99.9%+ purity.
6. Supporting Equipment
– Screens & Trommels – Classifies ore by size before processing.
– Thickeners & Filters – Dewaters slurry for efficient tailings management.
– Pumps & Conveyors – Moves material between processing stages.
7. Environmental & Safety Equipment
– Cyanide Detoxification System (SO₂/Air, H₂O₂) – Treats tailings to neutralize cyanide before disposal
