Enhancement of bauxite residue as a low-cost absorbent for phosphorus in aqueous solution, using seawater and gypsum treatments.
Cusack, Patricia B.; Healy, Mark G.; Ryan, Paraic C.; Burke, Ian T.; O'Donoghue, Lisa M.T.; Ujaczki, Éva; Courtney, Ronan (Elsevier, 2018-01-20)Bauxite residue (red mud), the by-product produced in the alumina industry, is being produced at an estimated global rate of approximately 150Mt per annum. Due to its highly alkaline nature, many refineries use neutralisation ... -
An evaluation of the general composition and critical raw material content of bauxite residue in a storage area over a twelve-year period
Cusack, Patricia B.; Courtney, Ronan; Healy, Mark G.; O’ Donoghue, Lisa M.T.; Ujaczki, Éva (Elsevier, 2018-10-09)Bauxite residue, the by-product produced in the alumina industry, is being produced at an estimated global rate of approximately 150 million tonnes per annum. Currently, the reuse of bauxite residue is low (∼2%), due to ... -
An investigation into the growth of lolium perenne L. and soil properties following soil amendment with phosphorus-saturated bauxite residue
Cusack, Patricia B.; Healy, Mark G.; Callery, Oisín; Di Carlo, Elisa; Ujaczki, Éva; Courtney, Ronan (Springer, 2022-04-07)Industrial by-products, such as bauxite residue, may be used to treat phosphorus (P)-enriched water and wastewater. Once fully saturated, they may be reused as P fertilisers. This study aimed to investigate the effectiveness ... -
The use of rapid, small-scale column tests to determine the efficiency of bauxite residue as a low-cost adsorbent in the removal of dissolved reactive phosphorus from agricultural waters
Cusack, Patricia B.; Callery, Oisín; Courtney, Ronan; Ujaczki, Éva; O’Donoghue, Lisa M.T.; Healy, Mark G. (Elsevier, 2019-04-19)Bauxite residue, the by-product produced in the alumina industry, is a potential low-cost adsorbent in the removal of phosphorus (P) from aqueous solution, due to its high composition of residual iron oxides such as hematite. ...
