The interaction of anode and electrolyte chemistry in copper electrorefining is complex. This is especially true with regard to the behavior of Group 15 elements (As, Sb, and Bi). To better understand this system, laboratory electrorefining experiments were conducted using commercial anodes with As/(Sb+Bi) molar ratios of 0.54 and 3.8 and an electrolyte collected from a commercial refinery. The effect of adding thiourea during plating was also examined. Twenty-one hour copper deposits were produced to simulate starter sheet production. The mechanical properties of the electrodeposited copper were measured using an industrially relevant empirical bend test and a one-point bend test developed by UFMG. To understand the differences in mechanical properties, the microstructure of deposits was examined using microscopy, x-ray diffraction, and electron backscatter diffraction.
