LCD screens are part of our daily life for entertainment, communications and networking. One of the key materials within an LCD screen is indium-Tin-Oxide (ITO). Although the ITO layer in LCDs is nano-meter thick, the volume of such screens produced is very large and thus accessing the required amounts of indium is important. Therefore recovering indium from discarded LCD screens is a potential opportunity to sustain future indium requirements. Efforts are being made by researchers to recover indium from LCD screens using conventional hydrometallurgical techniques where acids are used to leach indium. Very few studies reported non-conventional hydrometallurgical techniques such as use of sonication. In this study a comparison of conventional and non-conventional techniques is studied. Also the influence of the glass morphology on indium leaching was studied: as-leached LCD glass and ground LCD glass powder. It is found that, upon filtering, the ground LCD powder can concentrate indium in fine particle fraction and leave bulk of the glass ready for recycling. The sonication method was found to accelerate the indium leaching thus allowing for low volume acid usage. These studies also provided valuable results regarding the possibilities to vary acid concentration.
