Concentration of Tantalum .from the Bernie Lake Pegmatite Deposit, Manitoba

Interest has recently been revived in the recovery of tantalum from the Bernie Lake pegmatite deposit. A gravity concentration process was developed to give satisfactory recovery and concentrate grade. The application of high-intensity magnetic separation was also studied. A pilot-plant investigation that confirmed the laboratory testing and provided a commercial-grade concentrate is described.
