Njira yogwiritsira ntchito njira yothandizira kusinthitsa yokonza zotsogola-zinc sulfide zimaphatikizapo kutulutsa kofunikira, kulowerera kosiyanasiyana komanso kutulutsa maluwa ofanana.
Zilibe kanthu kuti ndi njira iti yomwe ingagwiritsidwe ntchito, mukumana ndi mavuto olekanitsidwa ndi kutsogolera kwa zinc-sulufule. Chinsinsi cholekanitsa ndi njira yovomerezeka komanso yotsika.
Popeza kuyambitsidwa kwa Galena kuli bwino kuposa ku Snahalerite, njira zonse zopondereza zinc ndikuwongolera zomwe zimagwiritsidwa ntchito nthawi zambiri. Njira zothetsera mankhwala oletsa zinc ikani njira ya cyanide ndi njira yopanda tsankho. Munjira ya cyanide, zinc sulfate nthawi zambiri imagwiritsidwa ntchito limodzi ndi cyanide kuti apititse patsogolo. Mwachitsanzo, chomera china chosinthana chimagwiritsa ntchito sodium cyanside ndi zinc sulfate kuphatikiza ku cumade kwa 20 ~ 30g / t, ndi zina, ndi zina. Kuchita kwatsimikizira kuti sikungochepetsa mlingo, komanso kumawonjezera chitsogozo.
Pofuna kupewa kuwonongeka kwa cyanide ku chilengedwe, ufulu wa cyanjade kapena njira yocheperako pakadali pano akulimbikitsidwa kunyumba ndi kunja. Njira zomasulira zakale zotsatila zimagwiritsidwa ntchito poyerekeza ndi zogawanika za zinc:
1. Chiwonetsero choyandama chimalepheretsa zinc
(1) Zicfate + sodium carbonate (kapena sodium sulfide kapena laimu);
Mfundo zina za Sulfar-zincfard zimatengera njira yokondweretsa. ZNO4 + Na2co3 (1.4: 1) adagwiritsidwa ntchito kupondereza Snsahalerite pomwe kutsogolera. Poyerekeza ndi njira ya cyanide, yotsogolera kalasi yokhazikika kuchokera ku 39.12% mpaka 41.80%, ndi kuchuluka kwa kalasi ya zinc yotsika kuchokera pa 43.60%, mpaka Kubwezeretsa Kukula Kuchokera 88.54% mpaka 90.03%.
(2) zimbani sulfate + sulfite;
(3) zikic sulpate + thiosulfate;
(4) sodium hydroxide (pH = 9,5, osonkhanitsidwa ndi ufa wakuda);
(5) Gwiritsani ntchito zinc sulfate yokha kuti ilepheretse zinc;
(6) Gwiritsani ntchito mafuta a so2 kuti aletse zinc.
2. Zizindikiro za zinc zimatsogolera
(1) laimu;
(2) Galasi yamadzi;
(3) Magalasi amadzi + sodium sulfide.
Njira zitatu zapamwambazi zomwe zili pamwambazi zimagwiritsidwa ntchito pomwe Galena ali ndi maxidids kwambiri komanso kuyamwa kwake kumakhala osauka.
Kwa chitsogozo choyandama, mankhwala akuda ndi Xanthate nthawi zambiri amagwiritsidwa ntchito ngati otola, kapena ethyl sulfide okha ndi kusankha kwabwino kumagwiritsidwa ntchito ngati otola. Zomera zina zakunja zimasakaniza sulmozucnic acid (a-22) ndi Xanthate.
Popeza laimu ali ndi vuto la Galena, pomwe pali Phriste yaying'ono mu ore, ndizothandiza kwambiri kugwiritsa ntchito sodium carbonate ngati chotsogolera chowombera. Pamene pyrite zokhala ndi waiwisi wokwera ndi wokwera, ndibwino kugwiritsa ntchito laimu ngati adwisi ya PH. Chifukwa laimu imatha kulepheretsa PRYNIT yomwe ikugwirizana, ndiwabwino kuwongolera.
Kuukitsa Kupsinjika Kugwiritsa Ntchito Copper Sulfate. Pofuna kupewa zamkuwa ndi xanthate kupanga mwachindunji kwa mkuwa xantha osakanikirana ndikuchepetsa mphamvu ya wothandizirayo, pomwe wamkuwa nthawi zambiri amawonjezedwa koyamba, kenako xanthate imawonjezeredwa mphindi 3 mpaka 5.
Pakakhala magawo awiri omwe ndi osavuta kuyandama ndi omwe akuvuta kuyandama ku Slubelerite, kuti asunge mankhwala olekanitsa ndikuwongolera, zomwe zimagwiritsidwa ntchito makamaka kutsogolera ndi zinki.
3.Method ya zinc ndi sulufule
.
1. Njira ya laimu
Izi ndi njira yogwiritsira ntchito Sulfar. Njira iyi imatha kugwiritsidwa ntchito kukonza raw ore ndikulekanitsa zinc-sulfur wophatikizidwa. Mukamagwiritsa ntchito njirayi, gwiritsani ntchito laimu kuti asinthe PH, nthawi zambiri kuposa 11, kuti zitsambukidwe ziwopedwe. Njirayi ndi yosavuta, ndipo mankhwala omwe amagwiritsidwa ntchito ndi laimu, omwe ndi otsika mtengo komanso osavuta kupeza. Komabe, kugwiritsa ntchito kwa laimu kungayambitse zida zachangu, makamaka ma pichelines, ndipo sulfur amangokhala osavuta kusefa, zomwe zimapangitsa chinyontho chachikulu cha chidwi cha chidwi.
Njira ya 2.hea
Kwa ma pyrites ena okhala ndi zochitika zapamwamba kwambiri, kuponderezana ndi njira ya laimu nthawi zambiri sikungathandize. Mukatenthetsa, madigiri a okopa a Scalite ndi agogo ndi osiyana. Pambuyo pa zinchur atatenthedwa amatenthedwa, odzozedwa ndi olimbikitsidwa, kuyatsidwa kwa pytete amachepetsa, pomwe zoyambira sterelitsate zidakali.
Kafukufuku akuwonetsa kuti zinc ndi sulufule zitha kulekanitsidwa ndi kuwotcha kwa nthunzi kuti kupatukidwe kwa zinc-sulufur wophatikizidwa. Kutentha kosiyanasiyana ndi 42 ~ 43 ° C, ndi kulekanitsidwa bwino popanda kutentha kapena kuwonjezera mankhwala aliwonse omwe amatha kupatula zinc ndi sulufule. Mndandanda wazomwe wapeza ndi 6.2% kuposa zinc servied yopangidwa ndi njira ya laimu, ndipo chiwombacho ndi 4.8%.
3. Laimu kuphatikiza cyanja yaying'ono
Pomwe mandimu okha sangathe kupondereza sulfide sulfide, onjezani pang'ono cyanjade (mwachitsanzo: Nacn5G / T pokonza chomera) kuti mugwiritse ntchito chomera cha zinc-sulufule.
(2) Masamba oyandama a Sulfar
Sulfur Dioxide + Njira yotenthetsera iyi yayikidwa mu Brunwick minerer prophul ku Canada. A Zinc amangokhala ndi chomera chomwe chomera chimakhala ndi pirte yambiri. Pofuna kusintha mtunduwo, malo otsekemera amathandizidwa ndi mpweya wa sulfuude ndipo umatentha ndi nthunzi kuti iponyere zinc ndikuyandama sulfur.
Njira yodziwitsira Sulfur dioxide yochokera pansi pa thanki yoyamba ndikuwongolera pH = 4.5 mpaka 4.8. Tumizani njerewere mu akasinja achiwiri ndi achitatu osangalatsa ndikutenthetsa 77 mpaka 82 ° C. Pamene pryte, pH ndi 5.0 ~ 5.3, ndipo xanthate imagwiritsidwa ntchito ngati otola. Maulosi a Flotation ndi akhali omaliza. Kuphatikiza pa Gorite, zogulitsa ziwanda zimakhalanso ndi zinc. Pambuyo posankhidwa, imagwiritsidwa ntchito ngati sing'anga ore ndikubwerera kumbali ya sing'anga kutsogolo kwa njirayi kuti mubwerere. Kuwongolera molondola kwa PH ndi kutentha ndiye chinsinsi cha njirayi. Pambuyo pa chithandizo, chinthu chazachitsulo cha zinc chowonjezereka kuchokera pa 50% mpaka 51% zinc mpaka 57% mpaka 58%.
