Flotation Theory of Gold Ore

Flotation Theory of Gold Ore

Golide nthawi zambiri amapangidwa mwaulere mu ore.Michere yodziwika kwambiri ndi golide wachilengedwe ndi miyala ya siliva-golide.Onse ali ndi kuyandama kwabwino, kotero kuyandama ndi imodzi mwa njira zofunika zopangira golide.Golide nthawi zambiri amaphatikizidwa ndi mchere wambiri wa sulfide.Symbiotic, makamaka nthawi zambiri symbiotic ndi pyrite, kotero kuyandama kwa golidi ndi kuyandama kwazitsulo zazitsulo za sulfide monga golide wokhala ndi pyrite ndizogwirizana kwambiri.Mayendedwe oyandama a ma concentrator angapo omwe tifotokoze pansipa ndi golide wambiri momwe golide ndi sulfide minerals zimakhalira pamodzi.

Malingana ndi mtundu ndi kuchuluka kwa sulfide, njira zotsatirazi zothandizira zikhoza kusankhidwa.
① Pamene sulfide mu ore makamaka pyrite, ndipo palibe heavy metal sulfide, ndipo golide makamaka sing'anga ndi zabwino particles ndi symbiotic ndi iron sulfide.Miyendo yotereyi imayandama kuti ipange golide wa sulfide, ndipo zoyandama zomwe zimasunthidwa zimakokedwa ndi mpweya wotuluka, potero kupewa kuchiritsa kwa cyanidation kwa miyala yonseyo.Ma flotation concentrate amathanso kutumizidwa ku chomera cha pyrometallurgy kuti akakonze.Golidi akakhala ngati tinthu tating'onoting'ono tating'onoting'ono ndi pyrite, cyanide leaching effect ya concentrate si yabwino, ndipo iyenera kuwotchedwa kuti isiyanitse tinthu tating'ono ta golide kenaka kenakake ndi mlengalenga.

② Pamene ma sulfide mu ore ali ndi chalcopyrite, sphalerite, ndi galena pang'ono kuwonjezera pa iron sulfide, golide ndi symbiotic ndi pyrite ndi heavy metal sulfide.General mankhwala dongosolo: Malinga ndi ndondomeko ochiritsira ndi dongosolo mankhwala a ore sanali ferrous zitsulo sulfide, kulanda ndi kusankha lolingana maganizo.Choyikiracho chimatumizidwa ku smelter kuti chiwunikire.Golide amalowa mkuwa kapena lead (kawirikawiri mkuwa wochulukirachulukira) amaunjikira kwambiri ndipo amachotsedwanso akamasungunuka.Mbali yomwe golidi ndi iron sulfide zimayenderana zimatha kuyandamitsidwa kuti mupeze iron sulfide concentrate, yomwe imatha kubwezeredwa powotcha ndi kuwotcha mpweya.

③ Pakakhala ma sulfide owopsa m'mlengalenga mu ore, monga arsenic, antimony, ndi sulfide wa sulfide, sulfide concentrate yomwe imapezeka ndi kuyandama iyenera kuwotchedwa kuti iwotche arsenic, sulfide ndi zitsulo zina mu concentrate kuti zikhale zosavuta Kwa ma oxide achitsulo osakhazikika. , perani slag kachiwiri ndikugwiritsa ntchito cholembera kuti muchotse zitsulo zosasunthika.

④ Pamene gawo la golide mu ore limakhala laulere, gawo lina la golide limakhala logwirizana ndi sulfide, ndipo gawo lina la golide limayikidwa mu mchere wa gangue.Ores amenewa ayenera anachira ndi mphamvu yokoka kulekana kuti achire ufulu golide, ndi kuti achire symbiosis ndi sulfide kudzera flotation Pakuti golide, malinga ndi golide zili tailings flotation, m'pofunika kuganizira ngati ntchito mankhwala leaching.Choyalacho chikhoza kuphwanyidwa bwino kenako n’kubowoleredwa mwachindunji, kapena chotsaliracho chikhoza kuphwanyidwa bwino chikatenthedwa kenako n’kubowoledwa.
