  • Can flotation be used in environmental applications?
  • It is concluded that this process will be soon incorporated as a technology in the minerals industry to treat these wastewaters and, when possible, to recycle process water and materials. In this paper, the use of flotation in environmental applications is fully discussed.
  • How floatation technology can be used in mining and industrial wastewater treatment?
  • Flotation technology can be incorporated in mining and industrial wastewater-treatment schemes in the following ways: as a unit process (ancillary or main process) to remove contaminants which are not separated by other means. Depending on performance (water quality), process water can be adequately treated and recycled;
  • Can flotation be used for heavy metal ions recovery?
  • Nowadays, wider applications have been found and compared to flotation for water and wastewater treatment. Stress in the present review paper was mainly applied to heavy metal ions recovery by flotation and the respective mechanism followed, being either ion, precipitate, or sorptive flotation.
