Small-scale gold mining is a significant economic activity in Ghana, providing livelihoods for thousands of people. The sector often uses rudimentary methods but has increasingly adopted mechanized equipment to improve efficiency. Below are some common types of small-scale gold mining machinery used in Ghana:
1. Manual & Semi-Mechanized Equipment
– Pans & Sluice Boxes – Traditional tools for washing and separating gold from sediment.
– Shovels, Picks & Hammers – Basic hand tools for digging and breaking rocks.
– Manual Rock Crushers (Mortar & Pestle) – Used to crush ore into finer particles.
2. Mechanized Mining Equipment
– Gold Detectors & Metal Detectors – Used to locate gold deposits (e.g., Fisher Gold Bug, Garrett AT Gold).
– Water Pumps (Diesel or Electric) – For alluvial mining to wash gravels (e.g., Honda pumps).
– Trommels & Rotary Scrubbers – For washing and screening gold-bearing gravel.
– Jigs & Shaking Tables – Gravity separation equipment to concentrate gold particles.
– Ball Mills & Hammer Mills – For grinding and crushing hard rock ores.

3. Heavy Machinery (Used by Larger Small-Scale Miners)
– Excavators & Bulldozers – For digging and moving large volumes of earth.
– Dredges (Floating or Land-Based) – Used in riverbeds for alluvial gold extraction.
– Crushers (Jaw Crushers, Impact Crushers) – For processing hard rock ores.
4. Mercury-Free Processing Equipment
– Gold Concentrators (e.g., Blue Bowl, Knelson Concentrator) – Alternative to mercury for fine gold recovery.
– Borax Method Equipment – Used as a safer alternative to mercury in gold smelting.
Challenges in Small-Scale Mining in Ghana
– Illegal mining (“galamsey”) causing environmental damage.
– Use of mercury leading to health hazards.
– Lack of access to financing for better machinery.
Where to Buy Machinery in Ghana
– Local suppliers in Accra, Kumasi, and Tarkwa.
– Chinese imports (popular due to affordability).
– International brands like Caterpillar, Komatsu, and Jiangxi Gandong Mining Equipment.
