Ngemuva kokusetshenziswa kwe-activator yokucubungula amaminerali: Enqubweni ye-flotation, umphumela wokwandisa ukuhamba kwamaminerali kubizwa ngokuthi ukwenza kusebenze.I-ejenti esetshenziselwa ukushintsha ukwakheka kwendawo yamaminerali futhi ikhuthaze ukusebenzisana phakathi komqoqi nendawo yamaminerali ibizwa ngokuthi i-activator.
Ukwenza kusebenze kungahlukaniswa ngokulandelayo: 1. Ukwenza kusebenze okuzenzakalelayo;2. Preactivation;3. Uvuko;4. I-Vulcanization.
1. Ukwenza kusebenze okuzenzakalelayo
Lapho kucutshungulwa i-polymetallic ores engeyona i-ferrous, indawo yamaminerali izosabela ngokuzenzakalelayo namanye ama-ion kasawoti ancibilikayo phakathi nenqubo yokugaya.Isibonelo, lapho amaminerali e-sphalerite ne-copper sulfide ehlala ndawonye, inani elincane lamaminerali e-copper sulfide liyohlale lifakwa i-oxidized libe yi-copper sulfate ngemva kokumbiwa kwensimbi.Ama-Cu2+ ion aku-slurry asabela nge-sphalerite surface ukuze ayisebenzise, okwenza kube nzima ukuhlukanisa ithusi ne-zinc.Kuyadingeka ukwengeza ama-ejenti okulungisa afana ne-lime noma i-sodium carbonate ukuze kunciphe, kanye “nama-ion angenakugwenywa” angabangela ukusebenza.
Okwesibili, preactivation
Ukuze ukhethe i-mineral, engeza i-activator ukuze uyivule.Lapho i-pyrite i-oxidized kakhulu, i-sulfuric acid yengezwa ukuze ichithe ifilimu ye-oxide ebusweni be-pyrite ngaphambi kokuntanta, iveze indawo entsha, ezuzisa ukuntanta.
ezintathu.lulama
Ibhekisela kumaminerali aye avinjelwa ngaphambili, njenge-sphalerite evinjelwe i-cyanide, futhi ingavuswa ngokungeza i-copper sulfate.
Okune.ivulcanization
Kubhekiselwa ekuphatheni kuqala insimbi ye-oxide yensimbi nge-sodium sulfide ukuze kwakhiwe ungqimba lwefilimu ye-sulphur mineral mineral ebusweni be-oxide ore, bese i-flotation nge-xanthate.
Ama-reagents okucubungula amaminerali asetshenziswa njengama-activators yilawa:
I-sulfuric acid, i-sulfurous acid, i-sodium sulfide, i-copper sulfate, i-oxalic acid, i-lime, i-sulphur dioxide, i-nitrate ehola, i-sodium carbonate, i-sodium hydroxide, usawoti oholayo, usawoti we-barium, njll.
