Inzuzo yegolide

Inzuzo yegolide

Izinsizakusebenza zegolide ezisebenzayo zingahlukaniswa ngezinhlobo ezintathu eziphambili:
Uhlobo lokuqala yi-arsenic ephezulu, ikhabhoni kanye nohlobo lwegolide ore. Kulolu hlobo, okuqukethwe kwe-arsenic kungaphezu kwama-3%, okuqukethwe kwekhabhoni kungu-1-2%, futhi okuqukethwe se-sulfur kungu-5-6%. Usebenzisa inqubo evamile ye-Cyanide Gold Extraction Process, isilinganiso se-leashing segolide yi-20-50%, futhi inani elikhulu le-NA2CN liyachithwa. Lapho ucetshiswa ubuchwepheshe be-flotation, yize kungatholwa i-High Gold ExpterRCRCRCRCRCROCRCRCRCRCRCRCRCRCRCRCRCRCRCRCRCRCRCROCRCRCRCRCRCRCRCRCRCROCRCRCRCRCRCRCRCRCRCRCRCRCRCRCROCRCRCRCRCRCRCRCRCRCRCRCRCRCRCRCRCROCRCRCRCRCRCRCRCRCRCRCRCRCRCRCRCTRCROCRCTRCROCRCROCTRACTRE, iqukethe amazinga aphezulu ezinto eziyingozi njenge-arsenic, ikhabhoni kanye kanye ne-antimony. Kuzoba nomthelela esigabeni esilandelayo senqubo yeGolide Extraction.

Uhlobo lwesibili luqukethe i-ores equkethe igolide lapho igolide ligoqwe khona ngamaminerali ama-gangue kanye nokungcola okulimazayo ngezinhlayiya ezinhle namafomu ama-microscopic. Kulolu hlobo, okuqukethwe kwensimbi sulfide kuncane, cishe ngo-1-2%, futhi kufakwe kumaminerali ama-gangue. Izinhlayiya ezinhle zegolide kumakristalu zi-akhawunti nge-20-30%. Ukukhishwa okujwayelekile kwe-Cyanide noma izindlela zokucebisa ze-flotation kusetshenziselwa ukukhipha igolide, kepha izinga lokutakula legolide liphansi kakhulu.

Uhlobo lwesithathu yi-Ore yegolide ngobudlelwano obusondelene phakathi kwegolide, i-arsenic kanye nesibabule. Isimo saso ukuthi i-arsenic kanye nesibabule yi-carrierrerals eyinhloko yegolide, kanti okuqukethwe kwe-arsenic kuphakathi. Inkomba ye-leashing yegolide yalolu hlobo lwe-ore usebenzisa inqubo eyodwa ye-cyanide yegolide yegolide iphansi. Uma igolide licebiswe yi-flotation, ingatholakala izinga eliphakeme lokutakula, kepha kunzima ukuthengisa ngoba liqukethe i-arsenic ngokweqile.

ubuchwepheshe bezimayini

Ukukhetha amakhemikhali

1. I-Gold Mineralization kanye nokwehlukana

Izindlela zokuhlomula zamakhemikhali zezimayini zegolide zifaka phakathi indlela efudumele yamanzi nendlela ye-cyanide. Indlela exubile indala futhi ilungele igolide elilodwa elihlanganisiwe. Kodwa-ke, kungcoliswa yingcosana futhi kuthathelwe indawo kancane kancane ngokuhlakanipha. Kunezindlela ezimbili ze-cyanidation, i-cranidation evusa ama-cranidation kanye nokuphamba kwe-cranidation.

2. Imishini yokukhetha amakhemikhali neyegolide

Indlela yamakhemikhali isetshenziselwa ukukhetha i-Ore yeGold Ore, ikakhulukazi indlela yomoya. Imishini esetshenzisiwe ifaka phakathi i-Zinc Powder Exchange Serven, i-Leashing Stiring Tank, njll. Idivayisi yokubuyiselwa kwe-zinc powder yithuluzi elithatha indawo ngodaka lwegolide oluvela ku-zinc powder.

Ithangi lokuvuselela ama-leaching liyithuluzi lokuvusa ama-slurry. Lapho usayizi wezinhlayiyana we-ore ungaphansi kwamamitha angama-200 kanye nokuhlushwa kwesixazululo kungaphansi kwama-45%, kwamiswa ukumiswa kungakhulisa ukugcwala kwegolide elichithiwe ethangini le-adsorption futhi kusheshise isikhathi sokufundisa.
