Descrizione
Il termine “coltan”, fino a poco tempo fa sconosciuto ai più, sta diventando tristemente noto a tutto il mondo. Deriva dalla contrazione di columbite e tantalite, due minerali della classe degli ossidi dai quali si ricavano il tantalio e il niobio, ideali come semiconduttori. Il coltan permette di ridurre le dimensioni e prolunga la vita delle batterie di telefonini, smartphone, telecamere, GPS, televisori al plasma, componenti per computer, fotocamere; è impiegato nell’industria aerospaziale e degli armamenti, specialmente missilistici, nelle centrali nucleari, per i motori dei jet, per gli airbag, le cellule fotovoltaiche, le fibre ottiche, i videogiochi, i visori notturni, i cerca-persone… L’80% delle riserve mondiali di Coltan si trova in Congo, e le grandi
multinazionali fanno di tutto per accaparrarsi il monopolio della sua produzione. Per farlo, forniscono armi ai signori della guerra, che sfruttano a loro volta i propri concittadini
imponendo loro di lavorare nelle miniere per 20 centesimi al giorno. Il tutto alimentando una guerra che ha causato oltre 4 milioni di morti, convertendosi nel conflitto più sanguinoso dopo la Seconda guerra mondiale. Alberto Vázquez-Figueroa ricostruisce le vicende e i misfatti compiuti dalle multinazionali in un romanzo avvincente che alterna finzione e storia,
intrecciando fatti e personaggi reali in una narrazione del tutto simile a un thriller. Pur essendo tristemente realtà.
