1. Estudo da influência de tensoativos em sistemas microemulsionados na extração de gálio e alumínio
Gallium is an important material used in the electronic industry whose demand in the world market is increasing in view of its potential applications. A selective technique is required to allow for the production of the metal, separated from aluminium. Due to the fact that microemulsions constitute an attractive alternative to metal extraction procedures, mi

2. Influence of Organic Solvents on Chalcopyrite Oxidation Ability of Thiobacillus ferrooxidans
It has been shown that organic solvents used primarily for the extraction of metals from aqueous leach liquors decrease both the surface tension of the aqueous phase and the chalcopyrite oxidation ability of Thiobacillus ferrooxidans. For the reagents and modifiers investigated, the order of inhibition was found to be LIX 70 < LIX 73 < LIX 71 < LIX 64N < LIX
