Tailings refer to the solid and fluid materials left over after the extraction of valuable minerals from mineral ores. The process of extracting minerals from ores starts with ore crushing and grinding to liberate the valuable minerals followed by physical separation processes and extractive metallurgy [220], [219], [189], [188] .

The most effective extraction of copper (84 to >90%) was achieved by bioleaching the tailings at 45 °C, using a defined microbial consortium, where elemental sulfur was added to the tailings and the pH of leach liquors allowed to fall to ∼pH 1, at which point anaerobic conditions were imposed.
