Abstract

The project proposed to design, build and operate a pilot factory for the extraction of gallium using Bayer liquor. The technology was developed for the extraction of high purity gallium - a strategic metal in the computer and telecommunications industry of high commercial value - using Bayer liquor, one of the main waste products from the processing of aluminum from bauxite. During the project ionic resins were also developed for the retrieval of gallium from the Bayer liquor and a substance to separate the metal from the resin. (AU)
