Process mineralogy involves the analysis of relationships between ore and gangue (accessory) minerals in order to optimize the recovery of target elements. Data from scanning electron microscopes with automated mineralogy and x-ray diffraction is used to model comminution and concentration processes. The modal mineral abundance and textural information at the particle level can impact the

2019/11/29Adsorption is considered to be one of the most effective technologies widely used in global environmental protection areas. The objective of this study was to generate a low cost agglomerated alumina adsorbent (A-1) for the effective removal of arsenic (V) from water and its comparison with a commercial agglomerated alumina (A-2).
