Abstract:
Rhenium is a rare precious metal on the earth. It is often found in molybdenite, porphyry and other minerals. It plays a very important role in the fields of aerospace and petrochemical industry. At present, one of the most important methods to recover rhenium resources is to extract rhenium from molybdenum concentrates. In this paper, the process of rhenium extraction from molybdenum concentrate is summarized, which including the whole wet process and the combined process of calcination and wet leaching. Meanwhile, the separation and extraction method of rhenium in solution containing rhenium is introduced and summarized. Finally the development direction of the comprehensive recovery and utilization of rhenium resources is prospected.
