Expansion of the Moma Titanium Minerals Mine in Mozambique.

Kenmare Resources appointed Aveng Engineering to detail design, construct and commission the expansion of the Moma Titanium Minerals Mine on the north east coast of Mozambique. The Moma Mine contains deposits of heavy minerals which include the titanium minerals ilmenite and rutile, as well as the zirconium silicate mineral, zircon. Aveng Engineering on their turn appointed Greene Consulting Engineers for the civil- and structural engineering design and construction monitoring services on the expansion project.

WHAT GREENE DID

• We designed the super structure of a floating process plant, 7 storeys high with a plan area as large as a rugby field. The total mass of the empty plant is in the order of 5500 tonnes and the maximum design mass of the plant was taken as 10 500 tonnes.
• The plant was built on 15 steel pontoons connected by 8 m deep steel trusses (strong-backs) which ensure that the operating plant can float in a large man made pond.
• The steel structures of the super structure we designed consist of a spiral building, crane building, a supporting structure for the vibrating screen, the mooring towers and pipe bridges.
