:: Moma Minerals Sands on Schedule
The US$220M Moma mineral-sands project in Mozambique is on schedule, with the first sub contracts having been awarded by the Bateman / Multiplex joint venture.
One of these provides for the turnkey supply of power to the site through a new 170km overhead power line from Nampula, and the electrical reticulation for the process plant, permanent accommodation camp and other site infrastructure. In addition, the installation of the aggregate crushing and screening facilities is underway with earthworks having started, while the civils contract is being finalised and work is expected to get underway soon.
The 27-month lump-sum turnkey contract for the provision of a mineral-sands processing plant and associated infrastructure at Moma is Kenmare Resources' second Mozambique project and the second-largest project to date, after the Mozal aluminium project, in this country. It commenced in August 2004.
The process being installed at Moma comprises dredging, concentrating and separating the mineral sands. The wet- and dry-processing plants, which have been acquired by Kenmare from BHP-Billiton's Beenup project in Western Australia, have been disassembled and await shipment to Mozambique.
The deposit will be mined using two 2500t/h floating dredges in a pond. The ilmenite-, rutile- and zircon-rich heavy concentrate will be separated from the lighter sand in the floating wet-minerals concentrator plant situated in the pond and constructed on top of floating pontoons.
The wet concentrate will be pumped to a dry-minerals separation plant approximately 2km from the wet-minerals concentrator plant. Four ilmenite products will then be produced with different titanium dioxide contents. Two will be separated from the concentrate without further beneficiation, while the remaining two will require roasting to reduce the chromite content of the ilmenite and increase the titanium-dioxide content.
The dry, saleable products will be fed by front-end loaders onto a 2,5 km-long overland conveyor for transporting to a specially constructed, 500 m-long export jetty. From this jetty, a 4000t capacity, self-unloading barge will transport the saleable product to offshore, seagoing bulk vessels.
