Jul 28, 2009· The recoveries of tin, tungsten, niobium and tantalum from lode ore deposits are usually very poor and rarely greater than 70%. Recovery at small scale workings of alluvial ore by hand and sluicing methods may not be as high, but for bigger dredging operations as much as 90% of the recoverable tin may be recovered.
Tantalum ore has characteristically grades of about 0.03% Ta 2 O 5, generally as a co-product of cassiterite and other minerals. Note that because of facile overgrinding, metallurgical recovery of columbite by crushing and milling hard-rock ore is often as low as 50%. Tantalum is silvery grey, heavy and very hard but malleable and ductile.
