The iron oxide copper–gold (IOCG) clan was firstly promulgated by Hitzman et al. (1992) and included several Proterozoic ore deposits (e.g., Olympic Dam) formed in an extensional setting. Subsequently, some newly discovered or re-classified deposits (e.g., in the Archean Carajas and Proterozoic Kangdian IOCG provinces) have been included and …

It works by exploiting differences in the surface properties of minerals. The process begins with the crushing and grinding of the ore to liberate copper minerals from the gangue. The ground ore is then mixed with water and flotation reagents, such as collectors, frothers, and modifiers, in a conditioning tank.

The next steps in the process exploit magnetic silica based nano-particles (SiO2) functionalized by different organic ligands for selective separation of individual REE. The nanoadsorbents are then easily separated from solution by magnet. Back extraction (stripping) of the wanted REE from the adsorbent is made by controlled decrease in pH.

This was achieved consistently until the first decade of the current century, but exploration since then has been wealth destructive. This outcome is a major issue for the mining industry unless reversed. We believe the technologies presently used to discover ore deposits will be as useful in making future discoveries as they were previously.
