Mining & Processing Operations

The above is a schematic of the Kenmare Moma mining and processing operation.

The Moma Mine will mine 22 million tonnes of titanium bearing sand per annum using two dredges as the primary mining devices floating on an artificial pond. Mined material will be pumped as a sand and water slurry to a floating concentrator plant. In this plant a heavy mineral concentrate will be separated from the sand using spiral separators. Sand tailings will be ejected at the rear of the concentrator and thus build up the rear of the pond.

Since the pond will be mined at the front and infilled at the rear, it will move slowly through the ore body on a designed minepath.

The heavy mineral concentrate will be pumped to a separator plant located near the deposit. In this plant the concentrate will be separated into distinct final products. One of these products will be roasted to improve it's characteristics. The final products will be stored in a shed with a storage capacity of 145,000 tonnes. Products will be exported by transportation along a conveyor from the storage shed to the coast along a jetty and loaded into a transhipment vessel.

This barge will be owned by the Mine and will transport product to bulk carriers moored at the offshore mooring point. The transhipment will then unload into the bulk carrier using its materials handling system. The average loading rate is expected to be 1,200 tonnes per hour.

The mine is expected to produce per annum, 800,000 tonnes of ilmenite and 21,000 tonnes of rutile, both titanium minerals, and 56,000 tonnes of zircon. The Mine is initially based on a 20 years operation at this level of production.

Wet Concentrator Plant

Dry Separation Plant

Moma will be a large volume and low cost operation. The key factors contributing to its low cost position are listed below:

• little or no vegetation
• sparsely to unpopulated high dunes
• no overburden
• fresh water for the dredge mining and processing
• moderate clay levels (3-12%)
• high (52-60%) TiO2 content in the ilmenite
• high value rutile and zircon co-products
• project will be served by low cost hydro electric power
• coastal position on favourable shipping route
• favourable taxation treatment by the Mozambican authorities
