For example, the Potrerillos Copper Mine disposed of mine tailings near its processing plant when it began operations (1920–1938). However, the copper tailings were subsequently disposed of in coastal areas using a technique called offshore tailings disposal (disposal of riverine and marine tailings).

The dewatering of tailings is one of the serious challenges that the mining and mineral processing industries have encountered internationally. Solid–liquid separation methods are applied to wastewater, which generally consists of fine particles and water; fine particles are settled in thickeners by the flocculation method and the cleaned water is …
