Abstract The proven global tin reserves were reported to be approximately 4.7 million tons (Mts) in 2016, and among these resources, only approximately 2.2 Mts can be recovered economically. The original tin deposits will be exhausted in several years, therefore, tin-bearing secondary resources, such as tin alloy, tin anode slime, e-wastes, …

Abstract This research aimed at recovering metals retained in the tailings from the flotation of copper (Cu) and cobalt (Co) ores conducted at the New Concentrator in Kipushi (NCK). Metals retention in the tailings (0.73% Cu and 0.37% Co) increased due to the removal of the gravity separation section from the processing circuit together with …

In this research, super-gravity separation achieved by high temperature centrifugation was used to recover copper and zinc from waste PCBs. At an optimized temperature of 1300 °C and a gravity coefficient of 1000, the total recovery values of Cu, Zn, Pb, and Sn were 93.23%, 80.86%, 94.54%, and 97.67%, respectively, in the whole separation process.
