METALLURGICAL SERVICES

Greek: ‘metallon’ (metal) and ‘ourgia ‘ (working)

Metallurgy is the science of extracting metals from ores, and their production and purification

We offer a variety of bench-scale and mini-pilot scale metallurgical services, which includes sample preparation, comminution, physical separation (gravity, magnetic and DMS), flotation and hydrometallurgical testwork.
