Abstract: Copper flotation waste which is the product pyrometalurgical production of copper from copper ores contains materials such as iron, alumina, calcium oxide, silica, etc. Copper flotation waste generally contains a significant amount of Cu together with trace elements of other toxic metals such as Zn, Co and Pb. A variety of techniques can be used for decontaminating and remediating copper slag. Environmental remediation technologies include in situ or ex situ techniques for decontaminating the polluted fields, such as soil-washing, physical separation, phytoremediation and leaching. The aim of the present study is to investigate the removal of the copper from copper flotation waste leachant using sepiolite. 2³ full factorial design was employed to study the effect of three factors which are contact time, adsorbent dosage and pH at two levels.
