4. Gallium Extraction
1. Gallium in Bayer mother liquor
In the process of producing alumina by Bayer process, about 70% of
the metal gallium in bauxite is leached with alumina, and about 30%
remains in red mud. With the circulation of the Bayer mother liquor,
the concentration of metal gallium in the Bayer mother liquor can be
accumulated to 100-300 ppm.
2. The method of chelating resin has become the main way to extract
metal gallium from Bayer mother liquor. The existing chelating
resins in the market still have many problems, such as a low
adsorption, poor strength, and harsh use conditions, which bring
certain difficulties to the industrialization process.
3.Metal gallium resource technology
The recovery of metal gallium is a waste recycling technology, with
better economic value, and has become a stable source of increased
profits for many aluminum industries.

7. Applications • World demand for gallium is expected to remain high as
demand for Ga-based products continues to increase
• Gallium is used in the microelectronic components of a
wide variety of products. The components include GaAs
(gallium arsenide), GaN (gallium nitride), and CIGS
(copper-indium-gallium selenide) direct band-gap
semiconductors
• Thermal convection in liquid gallium is used to study
aspects of planetary and astrophysical
magnetohydrodynamics, and because of its silvery color
and ability to form metal alloys, gallium is used to make
brilliant mirrors
• The LED industry is also expected to increase demand for
GaAs and GaN-based technologies that are used in the
backlighting of computer notebook screens and
flatscreen computer monitors and televisions, and in
general lighting application

9. Gallium oxide is needed for sputtering targets that consist of
indium, gallium, and zinc oxides. The IGZO or GIZO sputtering
targets are used in next generation displays, where high currents
and pixel densities make it necessary to use ever higher
performing materials.
