A method of recovering metal and/or oxide thereof from a slurry is described.
The
method involves magnetically separating at least a portion of any magnetic impurities
from the slurry and then leaching or dissolving at least a portion of any remaining
magnetic impurities in a slurry. At least one chelating agent can then be added
to the slurry and the solids can be recovered from the slurry by various separation
techniques. The methods of the present invention are particularly useful in the
recovery of tantalum and/or oxide thereof especially tantalum and/or oxide thereof
having a very fine size.
