Carbothermal recovery of zinc from brass ash: Mineral ...

Brass ash of composition (wt-%) 59·67Zn-9·22Cu-1·45Pb-2·61SiO 2-0·36Cl was treated by carbothermal reduction in a temperature controlled tube furnace. The aim of the work was to collect zinc in the form of metal and/or zinc oxide in the gaseous phase. Treatment temperature (950-1200°C) and time (15-180 min) were varied.
