Abstract

Copper anode slime is a byproduct of electrolytic copper refineries which usually contains many valuable elements such as Au, Ag, PGMs (platinum-group metals), Cu, Se, Pb, As, and Sb. Anode slime is generally considered as the main source of the world’ s Selenium and one of the important sources for the extraction of precious metals. Several methods have been used for processing and recovery of Selenium from anode slime. One of the prevalent common industrial methods is Sulfation roasting. In this research, the Sulfation roasting method was optimized to recover Selenium from Copper anode slime whichthat is able to minimize the environmental pollutions and energy consumption. A D-optimal design based on response surface methodology was used for modeling of the roasting stage. The effect of two parameters was investigated on the roasting process; of liquid to solid ratio (L/S), and temperature on the roasting process was investigated. The Selenium recovery was optimized and at the optimum condition of the L/S ratio of (1. 9 mL/g) and temperature of (247. 3 ° C), the Selenium recovery was found to be 99. 99%. The head sample of the Copper anode slime was characterized by x-ray diffraction (XRD), x-ray fluorescence (XRF), and inductively coupled plasma atomic emission spectroscopy (ICP-AES). The Selenium purity was determined to be 97. 08 % by ICP.
