To je pravda, modern\u00e1 elektronika je doslova \u201emestskou ba\u0148ou\u201c. Hoci sa v jednom smartf\u00f3ne nach\u00e1dza len zlomok gramu zlata, pri mili\u00f3noch vyraden\u00fdch zariaden\u00ed ide o obrovsk\u00e9 bohatstvo.<\/p>\n\n\n\n

Zlato sa v elektronike nepou\u017e\u00edva preto, aby bolo drah\u00e9, ale kv\u00f4li jeho unik\u00e1tnym fyzik\u00e1lnym vlastnostiam<\/strong>: je to vynikaj\u00faci vodi\u010d a na rozdiel od medi alebo striebra neoxiduje (nehrdzavie)<\/strong>. To zabezpe\u010duje dokonal\u00e9 spojenie aj po rokoch pou\u017e\u00edvania.<\/p>\n\n\n\n

Tu je preh\u013ead toho, kde sa ho nach\u00e1dza najviac a pre\u010do by ste star\u00fa elektroniku nemali len tak vyhodi\u0165.<\/p>\n\n\n\n

Ko\u013eko zlata sa d\u00e1 re\u00e1lne vy\u0165a\u017ei\u0165?<\/h3>\n\n\n\n

Pre lep\u0161iu predstavu o tom, ak\u00e1 bohat\u00e1 je t\u00e1to “odpadov\u00e1 ba\u0148a”:<\/p>\n\n\n\n

    Pre\u010do to nesk\u00fa\u0161a\u0165 doma? (Varovanie)<\/h3>\n\n\n\n

    Hoci vide\u00e1 na internete, kde \u013eudia \u201evaria\u201c elektroniku v kyseline, vyzeraj\u00fa jednoducho, je tu nieko\u013eko obrovsk\u00fdch riz\u00edk:<\/p>\n\n\n\n

    1. Smrtiace v\u00fdpary:<\/strong> Proces si vy\u017eaduje siln\u00e9 kyseliny (ako kyselina dusi\u010dn\u00e1 alebo l\u00fa\u010davka kr\u00e1\u013eovsk\u00e1).
