Leaching of iron from copper tailings by sulfuric acid

Copper tailing is the residual ore left after copper extraction during a floatation process, which is more difficult to recycle as compared to the copper slag. Its main components are fayalite (Fe 2 SiO 4) and magnetic iron oxide (Fe 3 O 4), accounting for more than 55% of the copper tailings. 1 In 2022, it is estimated that million tons of copper tailings were produced worldwide. 2
