Antimony compounds, primarily antimony xide and pentoxide, are often used as flame retardants for the printed circuit boards. Anode slime is a by-product of the copper electrolytic recovery process from the waste printed circuit boards (WPCB) [1, 2].Sb is traditionally leached from the anode slime to form an antimonial solution in …

Abstract. Antimony is becoming an increasingly critical element as the supply-demand gap is expected to exceed 10% over the period 2015–2020. Antimony production is primarily concentrated in China (90%) and as the industrial demand for this metal surges, attention has to turn towards the recovery of antimony from (industrial) waste residues and end …
