Biosorption of simulated aqueous solution containing acidic dyes by Azolla filliculoides [PDF]

open access: yes, 2014
Biosorption of acidic dyes using the live fern Azolla filliculoides was studied in a discontinuous system. Dye parameters, dye initial concentration and contact time were studied in temperature range of 25-30 ºC and pH=7. It was shown that increasing the

Biolixiviación en columnas de sulfuros polimetálicos del yacimiento de Aznalcóllar (Faja Pirítica Ibérica). [PDF]

open access: yes, 1991
Una alternativa al tratamiento clásico de los sulfuros polimetálicos a través del circuito flotación diferencial - fundición es el desarrollo de procesos hidrometalúrgicos eficientes que permitan la extracción selectiva de cobre, plomo y zinc.

Biohydrometallurgy in the recovery of metal values.

open access: yesIndustrial Data, 2001
In current times, and with regard to extractive metallurgy, the use of new technologies for the recovery os values that can be present in minerals or in their concentrates and which can be hardly extracted by means of conventional technologies are shown special interest. One of these new technologies is bacterial leaching.

Iron oxidation and mineral oxidation by moderately thermophilic bacteria [PDF]

open access: yes
The microbial oxidation of minerals is a commercially important process. Until comparatively recently only one organism capable of mineral oxidation has been extensively studied - Thiobacillus ferrooxidans. Several new, potentially commercially important
