Leading the way in offshore mineral exploration
IMAS has developed extensive know-how and expertise
in offshore mineral exploration. It offers customers a
range of services focused on the management of efficient
and effective exploration programmes.
Its exploration services include:
• identification and assessment of mineral resource
potential
• coordination of site surveys, mapping and sampling
programmes
• advice on regulatory and environmental reporting
Mineral processing services
Key to efficient wet mining systems is the optimal
combination of the excavation tool and the mineral
processing plant. Matching these so-called ‘games
of capacity’ is a crucial design feature of our mineral
processing advisory services:
• analysis of wet separation techniques
• process flow diagram development
• mass balance calculations
• capacity optimisation between extraction tool and
plant
• design envelope of processing plant
