Review of arsenic metallurgy: Treatment of arsenical ...

01-12-2017· Smelters can only treat copper concentrates in which the arsenic level is < 0.5 wt% and a penalty of $3 USD/kg arsenic is charged for an arsenic concentration over 0.2 wt%. In addition, arsenic is capable of forming compounds along the grain boundaries after copper solidification which negatively affect the mechanical and electrical properties of the resulting copper ( Safarzadeh et al., 2014b ).
