“…As shown in Figure 6, the presence of goethite is confirmed by the predominant peaks observed at 25, 39, 41, 43, 47, 63, and 74 theta degrees. A number of authors has reported similar results (Yang et al, 2017, Taleb et al, 2016, Ristić et al, 2013. Furthermore, the XRD pattern revealed that the synthesized product contained iron oxide nanoparticles both in crystalline and in amorphous state.…”

Pollution of water resources by acid mine drainage (AMD) has been an issue of primary concern in recent decades, since it negatively affects the environment and its suitability to foster life. As such, efforts to recover, valorise and beneficiate minerals acquired from AMD treatment process have been ongoing, albeit with minimal success. With that in mind, this study unpacks novel ways of beneficiating AMD via the synthesis of valuable minerals with myriads of industrial applications. To this end, real AMD was used to synthesize goethite, hematite, magnetite, and gypsum (product minerals). Drinking water was also reclaimed as part of the treatment process, hence rendering this system a zero-liquid-discharge (ZLD) process. For the synthesis of goethite, hematite, and magnetite, Fe(III) and Fe(II) were recovered via sequential precipitation in batch reactors. Lime was added to treated water to synthesize high-grade gypsum. Furthermore, reverse osmosis (RO) was employed to reclaim drinking water as per South African drinking water standards (SANS 241) specifications. Product minerals were ascertained using advanced analytical techniques. Concisely, this study proved that AMD can be beneficiated into valuable minerals, which could be utilized in a number of industrial applications. The profits from selling the product minerals can potentially aid in offsetting the running costs of the treatment process, hence making this

“…El tratamiento hidro-térmico a 298°C de la goetita obtenida por suspensión de hidróxido férrico amorfo gracias a la mezcla de nitrato férrico nano hidratado [Fe(NO 3 ) 3 .9H 2 O] con hidróxido sódico (NaOH) es otra vía para sintetizar cristales de goetita, aunque no resultaron nanopartículas totalmente puras ya que se evidenció presencia de nitrato de sodio formado en la reacción [24]. Se puede también obtener este nanomaterial impregnado en varios soportes como óxidos de grafeno [25], celulosa [26], copolímero de metacrilato de glicidilo [27], poliacrilamida [28], todos estos compositos fueron estudiados para la remoción de metales pesados en aguas de diferente procedencia.…”

Environmental pollution by heavy metals has been extensively researched using different materials and techniques but, this problem has not been fully resolved. High adsorption capacity of iron oxides such as hematite, magnetite, goethite and, ferrihydrite to remove arsenic are described in this review. There are many international investigations about the minerals of iron oxides and they describe the composition, properties, synthesis methods and involved variables. Active carbon, silicones and polymers had been used to obtain composites with iron oxides and they have gave better results to remove different anions and cations. The aim in this paper is to introduce studies already carried out and encourage research in this topic to take advantage of the particular characteristics of iron oxides and use them in the environmental remediation. In addition, it is important to introduce the natural iron oxides availability that have a lot of field to study. The literature search on the subject was carried out in Science Direct and high impact articles related to natural or synthetic oxides were used. Keywords: Arsenic, hematite, magnetite, goethite, iron composites. Resumen La contaminación ambiental por metales se ha estudiado mucho con diferentes materiales y técnicas, pero aún no se ha logrado resolver por completo este problema. La alta capacidad de adsorción de los óxidos de hierro como la hematita, magnetita, goetita, ferrihidrita, para la remoción de arsénico en agua son descritos en este trabajo de revisión. Existen muchas investigaciones internacionales de los óxidos de hierro en las que se expone la composición de estos minerales, las propiedades, métodos de síntesis y las variables que intervienen. El carbón activo, las siliconas y los polímeros son materiales que se han usado para formar compositos con estos óxidos que han contribuido a obtener mejores resultados en la remoción de diferentes aniones y cationes. Con este trabajo se pretende difundir estudios ya realizados e incentivar la investigación en este campo para aprovechar las características particulares de los óxidos de hierro y usarlos como remediadores ambientales. Ademas, es importante dar a conocer la existencia de óxidos de hierro naturales que dejan mucho campo por estudiar.
