Swelling of clay minerals during the leaching process
2020-5-1 Many researchers have been engaged in long-term research on the reason of the landslides in the ore areas. Mohan K et al. found that due to the inappropriate injection of leaching agent in the ore bodies, the clay minerals swelled after adsorption of water and its adhesion force dropped, leading to the landslide [].Luo et al. found that the ion-exchange process during leaching changes the ...

Solving Clay Problems in Mining Using Combined NIR
It is possible to calibrate the NIR for many different minerals (typically soft minerals). The use of a FT-NIR tool enables the mine to monitor selected minerals and apply the data for process improvement. However, XRD analysis is still required for the NIR data calibration, an essential process for mines.
