Abstract Among all iron oxides, hematite (α-Fe 2 O 3 ), goethite (α-FeOOH), and ferrihydrite (FeOOH⋅ n H O) are the most common mineral species. While immobilization of Mo 6+ by surface adsorption on ferric oxides has been studied extensively, mechanisms incorporation in their structure have researched little. The objective this study was to investigate relation between content its structural h...

The paper focuses on the mechanical treatment of natural goethite,quartz and clay minerals, aiming at improving their dispersion behavior in presence different dispersants. subject research activation is change state material under action forces, whereby newly created defined as “activated”. presents tests analysis possibility applying mechanoactivation mineral surface by grinding multistage pl...

The International Ocean Discovery Program (IODP) Expedition 349 recovered Miocene oceanic red beds overlying the basaltic basement in South China Sea. occurrence of provides an opportunity to understand deep-sea redox conditions when Sea was open western Pacific during Miocene. Here, we investigated iron oxide mineral contents along with major element compositions at Site U1433 reveal oxidation...
