12.11.2022The iron ore surface is hydroxylated upon contact with moisture and adsorbs H + or OH - from aqueous solutions, resulting in a surface with different electrical properties [ 44 ]. In acidic solutions, the surface hydroxylation of iron ore adsorbs H + from aqueous solutions to form Fe-OH 2+, making the surface positively charged.

Unconformity of Sediments : In many situations sedimentation is an interrupted process. Major breaks exist in sedimentation and are called unconformities. An unconformity can form when one set of beds rests upon the eroded or on the upturned edges of another different set of rocks either due to change in environmental condition or a break.
