Udindo wa lead nitrate mu mgodi wa golidi leaching

Dothi lonse la cyanide leaching ndi njira yakale komanso yodalirika yochotsera golide, yomwe imagwiritsidwa ntchito kwambiri popanga masiku ano.M'zaka zaposachedwa, kuti achulukitse kupanga golide, kuzindikira kupanga golide pamalopo, ndikuwonjezera luso lamakampani opanga mabizinesi, migodi yosiyanasiyana ya golide yakulitsa kuchuluka kwa ntchito yawo yotulutsa matope a cyanide.

Tinthu tating'ono ta golide mu ores osiyanasiyana nthawi zambiri ndi golide wapakatikati komanso wonyezimira, ndipo momwe golide amawonekera makamaka ndi golide wamkati ndi golide.Boma lophatikizidwali limathandizira kuti matope a cyanide abwere, komabe pali tinthu tating'ono tating'ono tomwe tikuti tinthu tating'onoting'ono tomwe timakutidwa ndi golidi m'matanthwe osiyanasiyana, zomwe zimapangitsa kuti golide achuluke.Zotsatira za kafukufuku wamchere zikuwonetsa kuti mtundu uliwonse wa ore ndi golide wovuta kutsika, ndipo cyanide yambiri imadyedwa panthawi ya cyanide leaching, zomwe zimakhudza kuchuluka kwa golide.
Njira yodziwika bwino ya matope a cyanide simangodya cyanide yambiri, komanso imakhala ndi chiwopsezo chochepa cha golide wapakatikati ndi wa sulfide wokhala ndi zonyansa zambiri monga mkuwa, arsenic, ndi sulfure.Kuonjezera nitrate yotsogolera kuti isagwiritsidwe ntchito musanayambe kutulutsa kungachepetse kutayika kwa cyanide ndikuwonjezera kuchuluka kwa leaching.
Kuonjezera nitrate nitrate pamaso pa leaching kungachepetse zomwe zili muzitsulo zosungunuka mu slurry, motero kuchepetsa kumwa kwa sodium cyanide.M'migodi ya golidi, tengani ore-mtundu wa high-flavor pyrrhotite-mtundu wa gold-2-copper ore monga chitsanzo.Zomwe zili mu pyrrhotite zimafika 23130%.Mu mawonekedwe a mamolekyu a pyrrhotite, pali atomu ya sulfure yofooka yomwe imapangidwa mosavuta kuti ipange sulfide yosungunuka, yomwe imadya cyanide yambiri panthawi ya cyanide leaching ndikutalikitsa nthawi yokonzekera.Ndipo Kuwonjezera nitrate nitrate kungachepetse kukhalapo kwa ayoni sulfide mu slurry ndi kukhazikika sungunuka sulfide, potero kuchepetsa kumwa sodium cyanide ndi kuwongolera leaching mlingo.
