Hier ein Auszug ueber die geschaetzte Ausbeute:
Interessant die Aussage,das ein Teil der Metalle an der Oberflaeche(kostenguenstiger&einfacher) gefoerdert werden kann.Der Gehalt liegt bei ca.2,8%,ist also nicht berauschend viel,etwas ueber das durchschnitts minimum!
Project is underpinned by a world-class rare earths-phosphate-uranium
deposit with current total resources of 30.3 million tonnes. The mineralisation is hosted over
an area of about 150 hectares and is exposed, in part, at surface. The resource contains
850,000 tonnes of rare earths (REO), 3.9 million tonnes of phosphate(P2O5) and 13.3
million pounds of uranium (U3O8)) and remains open ended along parts of strike and at
depth.
Following successful rare earth carbonate production, Arafura has now moved to the next
planned phase of the development program with a focus on production of a suite of Rare
Earth Oxides and the completion of the Bankable Feasibility Study. During 2011, samples
of Rare Earth Oxides for market assessment by potential customers will become available.
Annual production of 20,000 tons of REO is expected to commence in late 2013.
