The flotation tailing sample utilized in this study was provided by Eagle Mine, USA. The material was prepared to 80 % passing 75 µm by grinding a representative portion in a laboratory-size ball mill at about 80 revolution per min (rpm) for 10 min. The ground sample was consequently used for the leaching experiments and characterization studies.
Non-ferrous metal ores are primarily beneficiated by flotation process, which generates a multitude of mineral processing wastewater (MPW) [1]. The main pollutants in beneficiation wastewater are often residual organic flotation reagents and soluble metal ions (e.g., Cu, Pb, Zn, and Fe) [2], [3].

Yu et al. 15 proposed a separation process of coal flotation tailing, namely reverse flotation–grinding–re-separation, to obtain the clean coal product with a yield of 25% and an ash content of 13.96%. It is worth noting that the above re-separation processes of coal flotation tailing all include a grinding stage.
A large amount of tailing from the flotation processing of pyrite ore are accumulated and landfilled, resulting in serious environmental pollution and a waste of valuable elements such as Al, Ti, Si, etc. Aiming to extract alumina from coal-derived pyrite flotation tailing, the process has been proposed based on activation roasting-alkali leaching for desilication, followed by alumina ...
Even when the recovery of the gold and silver values from such ores by flotation is low, it may still be advantageous to float off the minerals which interfere with cyanidation, roasting and cyaniding, or possibly smelting, the concentrate for the extraction of its precious metal content; this is followed by cyanidation of the flotation tailing ...
Flotation tailing is a problematic mining waste, because contains sulphides that exposed to oxidising conditions generate acidic drainage and the subsequent metal mobilisation. In this study, a flotation tailing produced within an integral process for the treatment of polymetallic sulphide ores is cleaned and valorised seeking a better use of ...
