Emva kokusetyenziswa kwe-activator ye-mineral processing activator

Emva kokusetyenziswa kwe-activator ye-mineral processing activator: Kwinkqubo ye-flotation, umphumo wokwandisa ukujikeleza kweeminerali kuthiwa kusebenze.I-agent esetyenziselwa ukutshintsha ukubunjwa kwendawo yamaminerali kunye nokukhuthaza ukusebenzisana phakathi komqokeleli kunye ne-mineral surface ibizwa ngokuba yi-activator.
Ukuvuselela kunokwahlulwa ngokwezi: 1. Ukuvula okuzenzekelayo;2. Preactivation;3. Uvuko;4. Ukwenziwa kweVulcanization.
1. Ukuvula okuzenzekelayo
Xa kusetyenzwa i-polymetallic ores engeyiyo i-ferrous, i-mineral surface iya kusabela ngokuzenzekelayo kunye nezinye ii-ion zetyuwa ezinyibilikayo ngexesha lokugaya.Ngokomzekelo, xa i-sphalerite kunye ne-copper sulfide minerals zihlala, inani elincinci le-copper sulfide minerals liya kuhlala lixutywe kwi-copper sulfate emva kokuba i-ore ichithwa.I-Cu2 + ion kwi-slurry isabela nge-sphalerite surface ukuze isebenze, okwenza kube nzima ukwahlula ubhedu kunye ne-zinc.Kuyimfuneko ukongeza ezinye ii-agent zokulungisa ezifana ne-lime okanye i-sodium carbonate ukuze i-precipitate, kunye nezinye "i-ion ezingenakuphepheka" ezinokubangela ukuba kusebenze.
Okwesibini, preactivation
Ukukhetha iminerali, yongeza i-activator ukuyivula.Xa i-pyrite i-oxidized kakhulu, i-asidi ye-sulfuric yongezwa ukunyibilikisa ifilimu ye-oxide ebusweni be-pyrite ngaphambi kokuba i-flotation, iveze indawo entsha, enenzuzo kwi-flotation.
ezintathu.ukuchacha
Ibhekisela kwiiminerali eziye zavinjelwa ngaphambili, ezifana ne-sphalerite evinjelwe yi-cyanide, kwaye inokuvuswa ngokufaka i-sulfate yethusi.
Isine.uvulcanization
Ibhekisela ekuphatheni kuqala isinyithi se-oxide ore kunye ne-sodium sulfide ukwenza umaleko wefilimu yeeminerali zesalfure kumphezulu we-oxide ore, kwaye emva koko i-flotation kunye ne-xanthate.
Ii-reagents zokulungisa izimbiwa ezisetyenziswa njengezivuseleli zezi:
I-asidi ye-sulfuric, i-sulfurous acid, i-sodium sulfide, i-sulfate yobhedu, i-oxalic acid, i-lime, i-sulphur dioxide, i-nitrate ye-lead, i-sodium carbonate, i-sodium hydroxide, ityuwa ye-lead, ityuwa ye-barium, njl.
