ore gallium converting

An amine-phenol gallium compound is toxic to malarial parasites, including those resistant to chloroquine. Sources: The main commercial source of gallium is bauxite ore. Gallium production is a by-product of aluminum processing. Smaller quantities of gallium are extracted from sphalerite, other zinc sulfide ores, and some types of coal.

The results show that adding a small amount of indium (16.8 at%) to gallium leads to a significant indium enrichment of >83 at% on the topmost layer of the alloy. This enrichment dictates the CO 2 conversion pathway, leading to 98% faradaic efficiency toward formate at −1.90 V vs reversible hydrogen electrode (RHE). This study produces ...

Ultra-pure gallium has a brilliant silvery appearance, and the solid metal exhibits conchoidal fracture similar to glass. Most gallium is produced as a byproduct of treating bauxite (aluminum ore), and the remainder is produced from zinc-processing residues. So its production is dependent on the production of those principal metals.

An electrical current is run through the mixture, causing the carbon from the carbon anode to attach to the oxygen component in the alumina, yielding aluminum and carbon dioxide: 2 Al2O3 + 3 C > 4 Al + 3 CO2. This process takes place at temperatures between 940-980º C and yields an aluminum of high purity.
