Resumen
[ES] Las escorias mineras producen la contaminación por metales pesados de los suelos, y de sulfuros, que, por oxidación, dan lugar a una acidificación de los suelos y provoca la aparición del drenaje ácido de las minas.
En muchas ocasiones este drenaje puede llegar a contaminar incluso aguas destinadas a consumo humano. Acidithiobacillus ferrooxidans posee la capacidad de oxidar compuestos ferrosos a compuestos férricos puede ser utilizada para la obtención de minerales férricos, que son los más útiles en la industria siderúrgica y de esta forma se eliminaría un volumen considerable de escorias mineras, que se traduciría en un efecto positivo para el medio ambiente.
El objetivo fundamental de este proyecto es la biotransformación por acción bacteriana de residuos mineros sin valor y con un alto peligro de contaminación medioambiental, en compuestos útiles en la industria siderúrgica, y, por tanto, eliminación del medio ambiente de compuestos con alta capacidad contaminante.
[EN] Mining slag produces pollution by heavy metals from soils, and sulphides, which, through oxidation, lead to acidification of soils and causes the appearance of acid drainage from mines. In many cases this drainage can even contaminate water intended for human consumption. Acidithiobacillus ferrooxidans has the ability to oxidize ferrous compounds to ferric compounds can be used to obtain ferric minerals, which are most useful in the iron and steel industry and thus eliminate a considerable volume of mining slag, which would result in a positive effect on the environment. The fundamental objective of this project is the biotransformation by bacterial action of mining waste with no value and with a high risk of environmental contamination, into useful compounds in the steel industry, and, therefore, the elimination from the environment of compounds with a high contaminating capacity.
