Here is a very interesting piece of information that I found in the 1993-1994 Mining Engineering Handbook.

"AUSTRALIAN TITANIUM. Mineral Deposits Ltd. dredges for titanium sands in Australia, operating its 500 tph (450-t/a) cutter suction dredges 12 mo/tr, 7 days/wk, 24 hr/day in free-flowing beach sand dunes 100 to 150 ft (30 to 46 m3) in height. Running time is said to be 94%. Recovery is 92%, determined by tailings sand sampling, and recovery of ore reserves determined by drilling is 98%. A 0.5% heavy mineral feed grade is pumped from the suction cutter to a floating recovery plant where rutile, zircon, and ilmenite are recovered on MDL spirals and Reichert cones. As of July 1990, operating cost for the dredge and recovery plant was Australian $0.25/m3 or approximately US $0.32/m3 (US$0.24/yd3) without amortization, depletion, depreciation, interest, or overhead. The cost of the mining unit was $12 million in 1985...."

Very interesting indeed. The heavies are only running 0.5% and are being mined at a cost of $0.25 Australian/tonne. What is important to note is that it is not the percentage that the heavies run but the make-up of the heavies. This operation is no doubt high in zircon and rutile. This is a similar operation to what NRL is planning except this material is not run through a furnace to produce a pig iron and a slag.
