Abstract
Tin-bearing tailings of the Solnechny Mining and Processing Plant (MPP) in the Khabarovsk Territory are studied with a view to producing tin and copper concentrates. The features of the material constitution of tailings and their influence on the process flow diagram development are described. Processability of the Solnechny MPP tailings is tested, and PFD is developed using the modern methods of disintegration, including cavitation and ultrasound. The semi-commercial-scale implementation of the proposed PFD has allowed production of copper concentrate at copper content of 18.28% and recovery of 60.48%, tin concentrate at tin content of 11.35% and recovery of 50.88%, and rejects with the tin and copper contents of 0.139 and 0.154%, respectively. The recovery of tin and copper has made 46.66 and 38.45%.
