Use of Ochre from an Abandoned Metal Mine in the South East of Ireland for Phosphorus Sequestration from Dairy Dirty Water.

The article discusses the potential for ochre to sequester phosphorus in an environmentally sustainable fashion. Ochre deriving from coal mine drainage sites in the United Kingdom displays a high phosphorus retention capacity without highly mobilizing metals, indicating that it can potentially adsorb phosphorus from agricultural wastewaters and be used as a fertilizer. A study focused upon untreated acid mine drainage from an abandoned copper-sulfur mine in a catchment of southeast Ireland. Ochre was mixed with phosphorus-amended water in batch experiments and a maximum adsorption capacity was calculated from the Langmuir equation.
