Ukuqokelela iarhente yiarhente yeFlotation etshintsha i-hydrophobizetion yomphezulu weminerali kwaye yenza ukuba amasuda eminemu edadayo ajikeleze iibhubhu. Olona candelo lukhulu ukukhetha iingulus. Inezinto ezimbini ezisisiseko: (1) Inokuthathwa ngokukhethekileyo kumhlaba wesimbiwa; . IXanthate yenye yabaqokeleli ababalulekileyo!
Iipropathi zeXanthate:
I-XANATHATE yi-XANHATE, igama lakhe lesayensi le-hydrocarbyl dimiliocarbonate. Ithathwa njengemveliso yekharbonate apho i-ion enye itshintshwe yiQela le-Hydrocarbyl kwaye ii-atom ezimbini zeoksijini zithathelwa indawo yi-atom yesalfure. Ngokwesiqhelo ifomula i-r-ocssme, efana neSodium Ethyl XANHATE. R kwifomula ngokubanzi ihlala i-aliiphatic hydrocarbon iqela le-cnh2n + 1, iQela le-Hyperbon, iQela, kwaye lihlala lihleli i-NA (+), + ), kwaye iimveliso zemizi-mveliso zihlala zikhona (+). Iipropathi zeKaxtanthate kunye ne-sodium XANATE zilingana, kodwa i-kaxanate zizinzile kune-sodium Xelastate, nangona i-katanate ayisiyonto iphantsi kwe-xonthate yesodium. Zonke ziyanyibilika ngokulula emanzini, utywala kunye ne-acetone.
Ngokwesiqhelo, i-methyl XANANHATE kunye ne-Gantate ibizwa ngokuba yiBantanthate ephantsi iBantanthate, kwaye abo bane-byyl kwaye ngaphezulu babizwa ngokuba yi-Xanthate yeBanga eliphezulu. IXanthate yi-crystalline okanye umgubo. Ukungcola kuhlala kuhlala kutyheli-luhlaza okanye i-orenji-i-orenji ye-gelatinous ene-1.3 ~ 1.7 g / cm3. Ine-odor ye-pungent kwaye inetyhefu (iphakathi). I-chain ye-chain ye-chanhate inyibilikisi ngokulula emanzini, inyibilike kwi-acetone notywala, kwaye inyibilike kancinci kwi-ether kunye ne-petroleum ether. Ke ngoko, indlela ye-acetone-i-ether indlela exubeneyo inokusetyenziswa ukuphinda iphinde icoceke kwaye icoce iXanthate.
Ukusetyenziswa kunye nokugcinwa kweXanthate
Ubuchule bokuqokelela kunye nokukhetha iXanthate yeeMinerals ezahlukeneyo zihambelana ngokusondeleyo nemveliso ye-solkathi yokuhambelana ne-XATHATE. Izimbiwa zentsimbi eziqhelekileyo zihlala zahlulwe zangamacandelo amathathu ngokusekwe kwimveliso ye-sthyl chanthate: (1) I-CHCALYIL ESTYLS: Izinyithi eziwela kolu luhlu zibandakanya i-AU, AG, HU, CU, CD, i-CD, i-AU, i-AU, i-AG, cu, njl njl) kunye nentsimbi Iiminerali ze-Sulfide zezinto ezinjalo. . Izinyithi eziwela kweli nqanaba ziquka zn, fe, mn, njl njl. Ukuba i-xenthate isetyenziswa njengomqokeleli, kulula ukufezekisa ukwahlulwa kwe-chalfide ye-chalcofale ezizinto ze-chalcofake kwaye zentsimbi yentsimbi ye-sholfide ezizinto ezihamba ngesaphilayo. Nangona iimveliso zokuzithoba ze-Ethyl XANTHATER yeCobalt kunye ne-nickel zingaphantsi kwe-10 ^ -1 kwaye ziyimizobo ye-culfilic, zihlala zithambeka nge-Iron I-Iron I-Sulfide neMinerals zentsimbi. . Izinyithi zeli nqanaba zibandakanya i-CA, MG, Ba, njl njl. Ukuqokelela isiphumo kolu hlobo lweemineral zensimbi. Ke ngoko, iXntanthate ayisetyenziswa njengomqokeleli xa ihlela i-alkali i-alkali kunye ne-alkaline yomhlaba izimbiwa, iiminerali ze-oxide kunye neeminerals ze-silticate. Ngokubanzi, imveliso ye-solbiobaility ye-inyibilikhi yentsimbi incinci kunemveliso ye-solbabisity ye-sthyl chaxl chantate. Ngokwemigaqo yekhemikhali, akunakwenzeka ukuba i-XANANATE ANAIN X (-) ukusabela kumphezulu wezimbiwa zensimbi kwaye zibuyise (2-). Kuphela xa umphezulu wemineral yentsimbi yentsimbi ye-sulfide i-oxid i-oxid i-oxid i-oxid, i-S (2-) kumphezulu wezimbiwa zentsimbi itshintshwa ngu-OH (-), i-S2O3 (2-) ;, 2-), kwaye emva kweplasma, isinyithi xa imveliso ye-solshate incinci kunemveliso ye-oxide ihambelana ne-golhate, kunokwenzeka ukuba i-xenthate anhate ansoide X (-) Ukutshintsha i-anaon ehambelana ne-oxide yentsimbi kumphezulu wezimbiwa zentsimbi. I-XANANHATE idla ngokusetyenziswa njengomqokeleli weentsimbi zendalo (ezinje nge-AU, i-AG, Cu, njl. Njl. Ukwenzela ukuthintela i-hydrolysis, i-Doracupetion kunye ne-Oxidation egqithisileyo yeXantate, iXntanthate kufuneka igcinwe kwizikhongozeli zomoya. Kulumkele ukunxibelelana nomoya omthusayo kunye namanzi, unikele ingqalelo kumanzi romof kunye nokufuma, kwaye akufuneki ukuba ifakwe ilanga okanye igcinwe ixesha elide. Ifanele igcinwe kwindawo epholileyo, eyomileyo nenendawo enomoya. Isisombululo seXanthate esilungiselelwe iXanthate Akufanelanga ukuba ishiywe ixesha elide, kwaye amanzi ashushu akufuneki asetyenziselwe ukulungiselela isisombululo se-XANANATE. Isisombululo se-XANATHATO esisebenza rhoqo kwi-Shift, kwaye ukulungiswa kwe-XANHATE CORRORDER yemveliso ihlala i-5%.
