Zelts sākotnējā stāvoklī ir atrodams kvarca iežos pavedienu, plankumu un foliju veidā, bieži sajaukts ar sudraba minerāliem.

Vai arī to var atrast upju gultnēs, sajaucoties ar smiltīm, graudu un tīrradņu veidā.

Zelta ieguve

Zelta ekstrakciju var praktizēt ar trīs dažādiem procesiem: izlīdzināšanu , saplūšanu un cianidēšanu . Tomēr ne vienmēr ir nepieciešams izmantot visus trīs procesus.

Gludināšana notiek, izmantojot garus traukus, kas ļauj atdalīt zeltu, ļaujot lēnai ūdens straumei plūst. Faktiski atkritumi, kas ir vieglāki par zeltu, tiek vilkti kopā ar ūdeni, savukārt mazie zelta gabaliņi nogrimst konteinera apakšā.

Apvienojot , izejvielas tiek samaltas pulverī, kas pēc tam tiek apvienots ar dzīvsudrabu. Pēc tam dārgmetālu atgūst, destilējot amalgamu.

Cianidēšana ir vissvarīgākais ekstrakcijas process. Zelta rūdas apstrādā ar kālija cianīda šķīdumu, gaisa klātbūtnē zelts kūst un pārvēršas par auro-kālija cianīdu. Zelta atdalīšana no šī šķīduma notiek ar cinku un elektrolītiski.

Zelta īpašības

Zelts sākotnējā stāvoklī ir sarkanīgi dzeltenā krāsā, spīdīgs, nemainīgs un kaļams (viskaļākais no metāliem). Šī pēdējā iemesla dēļ un, lai to varētu apstrādāt, tas ir leģēts ar citiem metāliem. Neviena parasta skābe to neietekmē, izņemot ūdens regiju, hlora ūdeni un sārmainus cianīdus. Tā kušanas temperatūra ir 1063° un viršanas temperatūra 2600°.

Lielākie zelta ražotāji ir Dienvidāfrika, Ķīna, ASV un Austrālija.
