Hovor\u00edme o\u00a0medi striebre a\u00a0zlate. Preto by star\u00fd telef\u00f3n, alebo ak\u00e1ko\u013evek in\u00e1 elektronika, nikdy nemala skon\u010di\u0165 v\u00a0oby\u010dajnom odpade.\u00a0Na \u010do sl\u00fa\u017eia drah\u00e9 kovy v\u00a0elektronike\u00a0Spom\u00ednan\u00e9 kovy, teda me\u010f, striebro a\u00a0zlato, patria k\u00a0t\u00fdm najlep\u0161\u00edm vodi\u010dom elektrick\u00e9ho pr\u00fadu. Na prvom mieste sa nach\u00e1dza me\u010f, za \u0148ou striebro a\u00a0bronzov\u00fa medailu m\u00e1 v\u00a0tomto pr\u00edpade zlato. V\u00a0elektronike s\u00edce n\u00e1jdeme najviac striebra, no ani mno\u017estvo zlata nie je zanedbate\u013en\u00e9.\u00a0Trochu matematiky \u00a0Pod\u013ea ofici\u00e1lnych dohadov a\u00a0\u0161tatist\u00edk, sa v\u00a0jednom mobilnom telef\u00f3ne nach\u00e1dza nie\u010do okolo dvadsa\u0165 a\u017e dvadsa\u0165p\u00e4\u0165 miligramov zlata.V\u00a0prepo\u010dte to vych\u00e1dza, \u017ee tona mobilov obsahuje pribli\u017ene sto\u0161tyridsa\u0165 gramov tohto kovu. Tak a\u00a0teraz sa pozrime na to, kedy sa za\u010d\u00edna zlato \u0165a\u017ei\u0165 v\u00a0pr\u00edrode. Samotnej \u0165a\u017ebe predch\u00e1dza geologick\u00fd prieskum. Ak ten potvrd\u00ed, \u017ee sa v\u00a0tone horniny, vyskytuje minim\u00e1lne p\u00e4\u0165 gramov zlata, za\u010d\u00edna sa \u0165a\u017ei\u0165. Ak si to teda prepo\u010d\u00edtate, tak v\u00e1m jednozna\u010dne vyjde, \u017ee \u0165a\u017eba zlata priamo z\u00a0mobilov, je nie len jednoduch\u0161ia, \u0161etrnej\u0161ia k\u00a0\u017eivotn\u00e9mu prostrediu, no i\u00a0nieko\u013ekon\u00e1sobne ekonomickej\u0161ia. Z\u00a0tohto d\u00f4vodu sa vo svete roz\u0161\u00edril takzvan\u00fd Urban mining, v\u00a0preklade mestsk\u00e1 \u0165a\u017eba.

Samozrejme, \u017ee to nerobia z\u00a0ich l\u00e1sky k\u00a0pr\u00edrode. Hlavn\u00fdm cie\u013eom je zisk, av\u0161ak aj napriek tomu, pr\u00edrodn\u00e9 zdroje dostan\u00fa trochu odpo\u010dinku.\u00a0Predpoklad\u00e1 sa, \u017ee iba v\u00a0\u010deskej republike, sa v\u00a0star\u00fdch telef\u00f3noch, ktor\u00e9 maj\u00fa \u013eudia st\u00e1le doma, nach\u00e1dza viac ako dvesto kilogramov r\u00fddzeho zlata. Na Slovensku je to ve\u013emi podobn\u00e9. Predstavte si, \u017ee by v\u0161etko toto zlato op\u00e4\u0165 poputovalo na v\u00fdroby elektroniky.
