Umqondo we-flotation wegolide ore

Umqondo we-flotation wegolide ore

Igolide livame ukukhiqizwa endaweni yamahhala e-Ores. Amaminerali ajwayelekile kakhulu yigolide lemvelo negolide-igolide ama-ores. Bonke banokufukula okuhle, ngakho-ke flotation kungenye yezindlela ezibalulekile zokucubungula ama-ores wegolide. Igolide livame ukuhlanganiswa namaminerali amaningi we-sulfide. Ngokwe-Sybbiotic, ikakhulukazi ngokuvamile i-sybiotic nge-pyrite, ngakho-ke ukugcwala kwegolide kanye nokufakelwa kwensimbi sulfide ama-ores anjenge-pyrite ethwala igolide kuhlobene kakhulu nokuzijwayeza. Imikhuba ye-flotation yabaxhanganisi abaningi esizokwethula ngezansi ikakhulukazi yi-Oneres yegolide eningi kakhulu ne-sulfide minerals.

Ngokuya ngohlobo nenani lama-sulfides, izinketho zokwelashwa ezilandelayo zingakhethwa.
Lapho i-sulfide ku-ore ikakhulukazi, futhi azikho ezinye izinsimbi ezisindayo zensimbi, futhi igolide ikakhulukazi izinhlayiya eziphakathi nezinezinhle kanye no-sybiotic ngensimbi sulfide. Ama-ores anjalo athathwa ukukhiqiza ukugxila kwegolide se-sulfide, futhi ukugxila kwe-flotation bese kufakwa kusetshenzwe ukufuya komkhathi, ngaleyo ndlela kugweme ukwelashwa kwe-cranidation kwalo lonke i-ore. Ukugxila kwe-flotation kungathunyelwa nesitshalo se-pyrometallurgy ukucubungula. Lapho igolide lisesimweni sezinhlayiya ze-submacroscopic kanye ne-pyrite, umphumela wokuqondisa okuqondile we-Cyanide we-grant akakuhle, futhi kufanele awohloswe ukuze ahlukanise izinhlayiya zegolide abese.

Lapho ama-sulfides e-Ore aqukethe inani elincane le-chalcopyrite, i-sphalerite, kanye ne-galena ngaphezu kwe-iron sulfide, igolide yi-Sybbiotic nge-pywite yomabili nalezi zinsimbi ezisindayo zensimbi. Uhlelo Lokwelashwa Okujwayelekile: Ngokwenqubo evamile kanye nohlelo lwamakhemikhali lwensimbi engeyona eyokuhlanza insimbi, bamba bese ukhetha ukugxila okuhambisanayo. Ukugxila kuthunyelwa kuSmelter ukuze kucutshungulwe. Igolide lingena kwethusi noma lihole (imvamisa ukugxila kwethusi) ligxila futhi liyatholakala ngesikhathi senqubo yokunqwabanisa. Ingxenye lapho igolide nensimbi sulbiotic kungashintshwa khona ukuze kutholwe i-iron sulfide gxila, okungase kutholakale ngokunyathela nokugcotshwa komkhathi.

Uma kunama-sulfide alimaza umkhathi e-ore, njenge-arsenic, antimony, kanye nama-sulfide we-sulfide, i-sulfide gxila etholwe ukugcwala kufanele ithoswe ukushiswa yi-arsenic, sulfide nezinye izinsimbi ezigxila kalula ku-Conformal Metal Onides , gqoka i-slag futhi futhi usebenzise ipeni ukuze ususe ama-okoxide wensimbi aguquguqukayo.

Lapho ingxenye yegolide e-Ore ikhona eFree State, ingxenye yegolide ingu-Sybiotic nge-sulfide, futhi ingxenye yezinhlayiya zegolide iboshwe kumaminerali amagena. Ama-ores anjalo kufanele atholakale ngokuhlukaniswa kwamandla adonsela phansi ukuze alulame mahhala igolide, futhi athole kabusha i-symbide nge-sulfide ngokusebenzisa ukugcwala ngegolide, kuya ngokuqukethwe kwegolide okuqukethwe kwe-flotation, kuyadingeka ukubheka ukuthi usebenzise i-cheming leachings. Ukugxila kwe-flotation kungaba yinhlabathi kahle bese kukhaletha ngqo, noma izinsalela zokushiswa zingaba yinhle ngemuva kokushiswa ngemuva kokushiswa bese zikhokhiswa.
