Extraction of gallium from equipment bauxite hydrometallurgy
Gallium in the world production of 90% from the alumina production process of recovery.
Both type monohydrate and sanshui type bauxite, which is important organic component 3 oxidation 2 aluminium material, accompanied by scare metal gallium exist, however, extraction of gallium from equipment bauxite hydrometallurgy process effectively extracting gallium.
when a hydrometallurgical process bauxite, seed decomposition mother liquor circulation after many times, concentrate of 80%
85% of the gallium concentration in mother liquor.
Extraction of gallium from the mother liquor method is more, using centrifugal extraction machine extraction occupies the main position.
In the use of centrifugal extraction machine extraction, mainly include direct extraction, carbonate extraction method and extraction soluble anode alloy.
The extraction of gallium from equipment bauxite hydrometallurgy extraction process directly as shown in the figure below:
