Tomographic Imaging of Bauxite Grains Leached Using Hydrochloric Acid

X-ray computer tomography (XRT) is a three-dimensional, nondestructive, and thus reproducible examination method that allows for the investigation of internal external structures objects. Due to its characteristics, XRT technique has increasingly established itself as an alternative also applied in field mineral processing. Within this work, used investigate influence hydrochloric acid leaching iron-rich bauxites on grain composition. Acid promising beneficiation refractories. Many studies have already with can reduce Fe2O3 content bauxites. However, apart from process composition bauxites, aspects such exact constitution or porosity behavior rarely been considered so far. To address these open questions, analysis was examine characterize various By comparing identical grains before after leaching, it observed gibbsite penetration deeper, volume decreases significantly. In diasporic boehmitic clear edges be seen which iron reduced.
