Comparing Pretreatment by Iron of Electro-Flocculation and Chemical Flocculation
Desalination, 2007Abstract A comparison was made between two technologies: electro flocculation (EF) and chemical flocculation (CF), which may be used as pretreatment in wastewater treatment. Natural water reservoir or wastewater intended for reuse, that contains high concentrations of iron particulates, often requires particle destabilization and removal.

A large number of iron ore tailings (IOTs) are produced in steel industry, posing threat to the environment during its storage and disposal. To effectively reutilize Fe in IOTs, we propose a comprehensive utilization scheme: (1) most Fe in IOTs is extracted by concentrated hydrochloric acid to form FeCl3 flocculants; (2) after separation from the FeCl3

Selective flocculation of ultrafine iron ore 2. Mechanism of selective flocculation
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1995The mechanisms involved in the selective flocculation of hematite from kaolinite, using starch as the flocculant, have been investigated. Adsorption isotherms of starch on hematite and kaolinite were measured by a thermogravimetric method, supported by infrared analysis of the adsorbed species and zeta-potential changes on adsorption of starch.

Improving Flocculation and Dewatering Performance of Iron Tailings Thickeners
Journal of Water Process Engineering, 2019Abstract Most of the mineral processing and hydrometallurgical plants consume large volumes of water. A portion of this water is recycled to the process while the remainder is lost. This necessitates optimization of dewatering systems particularly in arid and semi-arid mining regions.
