- Tantalite Ore Processing
Through this process, tantalite gets more concentrated while moving down through the several steps of the milling procedure, and the tantalite recovery yield is reported at around 70% (GSE 2010). At the end of ore-processing facilities, the tantalite concentrate is transferred to stainless-steel trays and dried in a cabinet warmed with a …

Tantalum minerals contain 12 to 84 percent tantalum pentoxide; however, tantalum ores are low grade and contain only 0.01 to 1 percent tantalum pentoxide, which is equivalent to 0.1 to 10 kilograms per metric ton. As a result, to produce concentrates of tantalum, tantalite ore must be separated from other minerals in the ore.
